On the Right Tracks….

HANIX

Japanese manufacturer Hanix offers a wide range of machines from micro to around 8 tonnes. The intro model in the range is the H08B micro, packing a Kubota 10hp engine and twin gear pump into a diminutive frame. Just 700mm wide in narrowest mode, the machine’s tracks can move out to 900mm for stability. Into the 1.5 tonne sector are the H15B-2 and H15B Plus-2 models. A 17hp Mitsubishi motor powers both machines, which both feature a triple gear pump hydraulic system and option of standard or long arm. The Plus version designates hydraulic track adjustment, moving from 1,000mm out to 1,300mm.

Into the plus 2 tonne sector, Hanix offer the H22B (2.2 tonnes), H26C (2.9 tonnes) and H36C (3.5 tonnes) models. Power comes from 17 to 27hp Mitsubishi engines and hydraulic system combines twin piston and single gear pumps. Fixed undercarriages are standard on these models, and widths run from 1,380 to 1,580mm. Again, long and short booms are offered and cab is standard too. In the same size bracket as the H36C is a zero swing model, the H36CR. This 3.7 tonne machine features the same 27hp as engine as its standard guise cousin and identical hydraulic setup. The engine position means a minimal counterweight and a long, fixed undercarriage is said to aid in stability.

For those requiring machines of 4.5 tonnes and upwards, Hanix have five models including its newly introduced 5.5 tonne H55DR zero swing machine, launched officially at the Executive Hire Show in February. This machine is a new generation ‘D’ series model and features a 44hp Kubota engine, single 130 l/minute piston pump (with 80 l/minute PTO flow) and optional long arm spec. It also has auto engine idle and shutdown plus a five-sided cab design to allow door opening to within machine width. Standard swing machines cover 4.5 to 8 tonnes, and feature Mitsubishi engines throughout, in either 42 or 55hp guise. Standard three pump hydraulics are common through the lineup and the range leading H75C can be specified in standard or City Boom spec. The latter features a three-piece boom for working in more confined areas and within lower heights.

NEUSON

Neuson, the Austrian manufacturer, has a comprehensive range of models on offer a wide range of different weights and specs. The baby of the range is the 803 model, a sub 1 tonne machine only 700mm wide but fitted with an 18hp Yanmar engine, which is unusually large for a machine of this size. Neuson say the reason for this is to allow the engine to run at reduced revs, so making it quieter and more fuel-efficient. Extendable tracks to 860mm make the machine more stable when working conditions allow.

Slightly larger in the range are the 1404, 1503, 1903 and 2203 models covering the 1.4, 1.6, 1.9 and 2 tonne sector and all feature a common 24hp Yanmar powerplant. Standard is 990mm minimum width with optional extendable track up to 1,300mm on the smaller two models – standard on the larger models. The 2203 features a neat idea too – the Neuson Kippmatic system – which allows the body to tilt up to 15 degrees in any direction, meaning the boom is straight when the machine is not, such as when digging at an angle against a wall or on a kerb.

Moving up to the next size bracket, Neuson offer 5 models from 2.5 to 3.6 tonnes of which two feature zero tail swing. The standard swing models feature 37hp three cylinder or 48hp four cylinder Yanmar engines and standard fixed undercarriage. The 3703 model is equipped with the Kippmatic tilting system. Powering the two zero swing models (28Z3 and 38Z3) are 24 or 37hp Yanmar engines. Track widths of 1,570 or 1,740mm with 300mm wide shoes are standard and the larger model comes with Auto2 Speed transmission, which activates dual travel speed automatically when tracking.

The 5 to 8 tonne sector is covered by four models that cover both zero tail and what Neuson call “small turn” variants. Zero tail models are 5 and 7.3 tonnes weight, and feature 48 and 70hp engines respectively. 400 and 450mm wide tracks offer good stability and both machines are standard with Neuson’s safety cab with optional air conditioning and air seat with Auto2 Speed transmission also part of the package. The “small turn” models, designated 6003 and 8003, are 5.5 and 7.6 tonnes respectively. Running on 400 or 450mm tracks, both models feature a cab as standard and Auto2 Speed transmission too. Overhang is minimal but if this is acceptable for their situation then the user gains more cab space, more engine power and a longer boom to outweigh the zero swing advantage.

VOLVO

Volvo offers a wide range in the sub 8 tonne market. Their offering kicks off with the 1.5 tonne, 15hp EC15B, which has three variants – XR, XT and XTV, all with either canopy or cab option. The difference between the XR and XT is the latter has twin speed tracking but both have a fixed track system at 980mm. The XTV has variable track adjustment out from 980 to 1,330mm with twin speed tracking too. The XR and XT models have a closed centre load sensing hydraulic system whereas the XTV utilises a triple gear pump.

The slightly heavier EC20B model (1.8 tonnes) comes in XT and XTV versions, with a 15hp engine and cab as an option. Track system extends from 1,000mm up to 1,350mm on the XTV and twin speed tracking is standard on both variants. XT has fixed track width.

Moving above 2 tonnes, the EC25 and EC30 models weigh in at 2.7 and 3 tonnes respectively. Powered by 23 and 24hp Mitsubishi engines, both machines have a closed centre load sensing hydraulics system and fixed track system. Wide opening rear panels allow good access to the engine for checks and service.

The 3.5 tonne EC35C model features load sensing hydraulics system powered by a Volvo 4 cylinder engine that develops 36hp. Twin speed tracking and 300mm wide rubber tracks are standard, with options that include long reach dipper and air conditioning. The control system features an ISO/SAE switchover valve and right hand electro proportional activation of the boom swing and attachments. At 5.5 tonnes, the Volvo EC55B Pro features a 52hp Volvo four cylinder engine, variable displacement “total power control” hydraulics and boom offset of 130 degrees. Maximum dig depths are 3,820mm with standard arm, or 4,180mm with long arm option.

For those requiring a short swing type machine, Volvo has five models on offer. The 2.8 tonne ECR28 and 3.2 tonne ECR38 models have Volvo three cylinder engines developing 19.3 and 27.6hp respectively. A common load sensing hydraulics system is in place too, as is an easy to see operator panel. When lifted up, the left hand console locks out all arm and foot controls for safety. The 4.8 tonne ECR48C has a 36hp Volvo D2 engine, 100 l/minute load sensing pump and 132 degree boom slew angle. A 1,400mm dipper is standard, with optional 1,800mm long reach available.

For larger requirements, Volvo produces the 5.5 tonne ECR58 and 8.5 tonne ECR88 models. Engines are 51 and 57hp four cylinder Volvo units and both machines have closed centre load sensing hydraulics – the 5.5 tonne machine putting out 130 l/minute and the 8.5 tonner offering 174 litres. Also standard is an automatic return to idle function for fuel saving plus fingertip proportional controls of boom swing and auxiliary functions.

TAKEUCHI

Japanese manufacturer Takeuchi offer an extensive range of machines from micro to 8 tonne, with the white and red range gaining quite a following for reliability and ease of use with landscapers. Standard and zero swing models feature across the lineup.

Starting off the range is the customary micro machine, designated the TB108, which tips the scales at just 835kg and the tape measure reads just 680mm at the narrowest track setting. The machine is powered by a 9hp Yanmar engine and features extending track width to 900mm, standard two-way hydraulics to arm and folding ROPS frame.

Moving to the common 1.5 tonne sector, Takeuchi manufacture two models – the TB014 and TB016. The former weighs a shade over 1.4 tonnes with a canopy setup, features a 12hp Yanmar engine and 980mm operating width. The TB016 is slightly heavier at 1.5 tonnes in canopy guise but features similar features. Track width adjustment is standard, allowing the operator to move the width down to 980mm for access or up to 1,300mm for more stability when working.

The TB125, 135 and 145 are built within the 2.8 to 4.8 tonne sector, and feature a standard tiltable cab with suspension seat and seat belt. Variable flow hydraulics on the auxiliary circuits is standard as is an engine decelerator button to aid the operator in reducing fuel usage. All machines are said to allow straight travel with boom and swing functions, so grading can occur with a bucket in use on the move. Yanmar engines from 22.5 to 37.5hp power these models. Topping the scales at 7.3 tonnes is Takeuchi’s TB175 with a 58hp engine and auxiliary oil flow of 69 l/minute. Featuring a wide-angle boom swing and auto shutdown, the TB175 can dig to a 4,590mm depth.

In near zero swing, Takeuchi now offer four models in their range. The TB23R short tail swing machine comes in at 2.4 tonnes with a canopy, and features both left and right offset dig capability. An 18.5hp Yanmar engine is housed under a tilting TOPS/FOPS cab. FR (meaning Front and Rear) designated near zero swing models come in the form of the TB138FR (3.8 tonnes), TB153FR (5.5 tonnes) and TB180FR (8.3 tonnes). FR offset models all feature a cab over track width of just mere centimetres say Takeuchi, meaning operators can work up close to walls and fences. A foot pedal operates the boom swing function so, say Takeuchi, there is no need to reposition the machine as often. A one-touch decelerator function is fitted to the right hand joystick on all models, and power comes from 28, 39 and 61hp Yanmar engines.

Hyundai provide several models into the UK mini/midi market, including two zero swing machines. The 1.5 tonne 15-7 model starts off the Hyundai range and comes with a 17hp Mitsubishi engine, triple gear pump with a 45 l/minute output, and choice of cab or canopy. Steel tracks can also be specified as can a longer arm, which can also slew 80 degrees to the left and 50 to the right. The 15-7 is just 1,000mm wide. The 16-7 and 22-7 versions feature the same engine as the 15-7, plus similar boom slew characteristics. The 16-7 runs on the same triple gear pump system while the 22-7 utilises a twin piston/single gear setup. Weighing in at 1.6 and 2.2 tonnes (in basic canopy variant), the smaller 16-7 features extendable track width from 1,000 to 1,300mm with the 22-7 having a fixed 1,380mm configuration.

The 2.8 tonne 28-7 has a 24hp engine, twin piston/single gear hydraulics, cab as standard with canopy option and 1,470mm fixed width. Long arm is optional too. The 3.5 tonne sector is catered for by three Hyundai models – R35-7, R35-7Z and R36N-7. The R35-7 is a 3.3 tonne machine with a 27hp Mitsubishi engine and fixed 1,580mm width track undercarriage. As per the 28-7, canopy is an optional choice. The zero swing R35-7Z and R36N-7 are powered by 27hp Yanmar and Mitsubishi engines respectively and offer 3.5 tonne performance up close to walls and obstacles. The R36N-7 has the triple pump system as found on the smaller models, whereas the R35-7Z is equipped with a twin variable displacement system with gear unit for the pilot circuit. This machine was launched at BAUMA 2007 event.

Hyundai offer one 5.5 tonne machine – the 5.7 tonne 55-7, which features a 53hp Yanmar engine, which Hyundai claim is the largest available in this class of excavator. An offset boom swing angle of 130 degrees is standard as is a twin variable displacement pump hydraulic system. Topping the Hyundai midi range are the 7.5 tonne R75-7 and 7.8 tonne R80-7 models. The R75-7 has a 55.5hp Mitsubishi engine and twin piston/single gear hydraulics. Running on standard or steel tracks, the R75-7 is only available with a cab.

NEW HOLLAND

New Holland Kobelco’s range of mini and midi excavators encompasses some thirteen models from 1 to 8 tonnes. The micro offering in the range is the E9SR model, which features an 8hp Yanmar power unit, operating weight of just over 1 tonne and minimum width of 750mm. Extendable tracks mean that overall width can be extended out to 980mm when conditions and space allow. Slightly larger sees 1.6 and 1.8 tonne models in E16 and E18 designation. The E16 model offers fixed track width of 990, extenable to 1,300mm on the E18. Twin gear pumps provide the oil power via a 3 cylinder 15hp Yanmar engine, and New Holland’s Total Flow system is said to deliver simultaneous control of all movements. Cab is optional on these models.

A zero swing version of the E18, the E18SR, features a 2,120mm working distance with the boom and dipper pulled in, so fairly compact for working in tighter areas. Variable undercarriage also features too. With the Smart Hydraulic System, which has three pumps, the third dedicated to working the blade and swing when required but directed to the digging hydraulics on demand. New Holland claim this machine has many larger machine features in a compact package.

A common 23hp Yanmar engine provides power to the 2.2 tonne E20.2SR, 2.5 tonne E22.2SR and 2.7 tonne E27.2SR models, which feature the same Smart Hydraulic System as the E18SR model. A larger cab than the original SR series is fitted to these models and wide opening panels offer good access all round to the engine, hydraulics and service points. Undercarriage is fixed width but the drive system features automatic downshift as standard build. Within the 3.2 and 3.8 tonne sector are the E30.2 and E35.2SR zero swing models that feature 30hp engines. Again, the hydraulics are the same as the smaller models and both can be specified with cab or canopy. Larger 4 and 5 tonne models (E40.2 and E50.2SR) feature the same specification as the 3.2 and 3.8 tonne machines, but have a 43hp engine.

In the plus 7 tonnes sector, machines move to what New Holland call their ‘midi’ range and both zero swing 7 and 8 tonne models feature rubber or steel tracks, and powered by the same Isuzu 55hp engine. The E70SR is optional with a side boom, so access to tighter digging areas is easier. Both machines feature New Holland’s Smart Hydraulic System combined with an easy to select working modes switch. This allows the operator to choose his work mode – Heavy duty, standard or precision, and the hydraulics respond accordingly to that requirement.

HITACHI
Hitachi offer a comprehensive range of models up to an 8 tonne capacity. They encompass both standard and zero swing variants. For those requiring a micro machine, the 810kg EX8-2B may fit the bill. Featuring a Kubota 8.5hp engine, the machine can dig to 1,525mm and has a variable undercarriage which can narrow down to 720mm on 180mm wide tracks. Twin gear pumps provide the hydraulic flow.

For mini machines, Hitachi starts off their range with the ZX16 and ZX18 models. Both feature an Isuzu 11.8hp engine and twin variable/single gear pump hydraulics system (offering a total of 42.6 l/minute). The main difference in the two models is the ZX18 features an extendable undercarriage, allowing width changes from 1,000 up to 1,300. The ZX16 is fixed at 1,000mm. Cab or canopy can be specified on both machines. For 2.5 and 3 tonne users, Hitachi offer the ZAXIS25 and ZAXIS30 machines. With 18.4 and 27.1hp engines respectively, both have the Hitachi Optimum Hydraulic System (OHS) triple pump setup, with 67.1 and 102.4 l/minute flow respectively. Tracks are fixed at 1,400 or 1,550mm width and both machines are standard with hydraulic breaker piping on boom.

In the 4-5 tonne bracket, the ZAXIS40 and 50 models have the same 36hp Kubota engine and OHS hydraulics, with 117.6 l/minute flow. Standard on 400mm rubber shoes, both machines can be specified with 400 or 550mm steel grousers for pure offroad use. Both also have a boom slew angle of 90 degrees left and 50 degrees right, and are almost identical apart from their operating weights otherwise.

Users who need a 6 to 8 tonne machine have a choice of two Hitachi models. The 6.4 to 7.57 tonne ZAXIS70 features a 52hp Isuzu engine and is married up to triple variable displacement pump system to provide over 170 l/minute of oil flow. A blade can be specified depending on user needs, as indeed can a longer undercarriage (machines are indicated by LC designation). A standard arm of 1,620 or 2,120mm is available, plus the option of an offset 1,620mm variant. The slightly heaver ZAXIS80SB and SBLC models come in at between 7.36 and 8.21 tonnes, and feature 52hp engine power, as per the ZAXIS70 version. Again, LC variant means longer undercarriage (by some 150mm) and these SB machines feature a slewing boom for closer working to obstacles.

The zero swing range starts with the ZAXIS10U-2 micro, weighing in at 1.1 tonnes with a 12.8hp Yanmar engine. Just 910mm wide at its narrowest, the 10U-2 has a short rear end for close up working, and can extend its tracks to 1,000mm when possible and retract down to 760mm. A collapsible TOPS makes for easier access into height restrictive sites too. Twin gear pumps provide 21.2 l/minute of flow to the main circuit.

Next up is the ZX17U-2, which weighs in at 1.9 tonnes and features a 14.8hp Yanmar engine. An open centre hydraulic system with twin variable displacement and single gear pumps provides a 50.9 l/minute oil flow. Undercarriage extends from 970mm to 1,280mm. Zero axis swing allows close up working and there is option of standard or long boom. The ZX22U-2, at 2.21 tonnes, features a 19.6hp Yanmar engine and 73 l/minute oil flow from triple pump system. Available in cab or canopy version, the ZX22U-2 is just 1,450mm wide (fixed undercarriage) and standard on 250mm wide rubber tracks, with optional grouser or rubber pad types.

Hitachi’s 2.9 tonne zero swing machine, the ZX27U-2, features a 26.4hp Yanmar engine with the machine available with cab or canopy option and either standard or long arm. Triple pump hydraulics provide the oil flow and a fixed undercarriage width of 1,550mm is standard. Slightly heavier (at 3.26 to 3.41 tonnes depending on cab or canopy spec) is the ZX30U-2, featuring a 29.9hp engine and around 106 l/minute oil flow. A choice of arms is available, either in 1,170 or 1,520mm and boom slew can be up to 134 degrees in total with a canopy machine.

At 3.5 tonnes, the ZX35U-2 features a 30hp engine, twin travel speed and 106 l/minute oil flow. Cab is optional as is a longer arm (1,715mm instead of standard 1,315mm). This also includes another 230kg counterweight. The 4 to 5 tonne offering from Hitachi includes the ZX40U-2 and ZX50U-2, with weights from 4.6 to 5.02 tonnes. A Yanmar 40hp engine powers both models, which are available with canopy or cab option plus option of 1,680mm long arm if required, replacing the standard 1,380mm unit. A single 125 l/minute variable displacement pump provides oil flow to both models, and an 80 degree left/60 degree right boom slew angle is common to both canopy and cab versions.

Topping the sub 8 tonne zero/short swing range is the ZX85US ultra short swing model. This has an Isuzu 54hp engine, triple pump system (two piston, one gear), auto acceleration and idle features, varying working functions and monitor panel for the machines diagnostics. Arm length can be 1,620 or 2,120mm and the ZX85US can be equipped with a blade if required. Offsetting of digging to the side of the cab allows for very minimal swing radius.

CASE CE
The Case mini/midi range (developed in conjunction with Japanese manufacturer Sumitomo) covers 11 models up to the 8 tonne mark. The two smallest models, the CX16B and CX18B, are 1.6 and 1.7 tonne machines both featuring Yanmar 15hp engines, the larger machine offering variable track width from 990 to 1,300mm. Zero tail swing makes it to the 2.2, 2.5 and 2.7 tonne CX20B, CX22B and CX27B models. Machine widths of 1,400mm (CX20B and CX22B) or 1,500mm (CX27B) are standard with fixed tracks, and Yanmar engines again provide the power. Cab and canopy options depend on model.

Moving up above 3 tonnes, Case market the CX31B and CX36B; both zero swing machines. Featuring a 30hp Yanmar engine in both models, these are available with canopy or cab, weighing in at 3.2 and 3.8 tonnes respectively (in canopy form). Adding to this line-up are the CX40B and CX50B, the last of Case’s “Mini” range. Both zero swing machines, these models feature a similar specification to the smaller Case models and have the same engine and cab/canopy options.

In 7 and 8 tonne guise are the CX75SR and CX80. The 7.5 tonne CX75SR has a 52hp Isuzu engine, twin variable displacement piston pumps (plus single gear pump for dozer) and short radius features, hence the SR designation. This specification includes shorter upper structure at rear, the foot of the boom is closer to the upper structure and cab within the swing radius, thus allowing the machine to rotate within a 3,600m diameter. The machine can be specified with a mono or offset boom. The larger CX80 (at 8.3 tonnes) features the same 52hp engine as the CX75SR and same hydraulics specification too. A standard type boom is the only available, but dipper options are either 1,700 or 2,100mm. Steel tracks are standard with rubber pads available for sensitive areas.

KUBOTA

Perhaps the instigators of the mini excavator during the late 1970s, Kubota continue to develop a variety of machines in the sub 8 tonne sector. Their current range covers 17 models in two sectors – the U and KX variants. U models are zero swing types, and start at the 1 tonne U10-3. This compact micro model is powered by Kubota’s own 10hp engine, has variable track width from 750 to 990mm to enable doorway access (zero swing when the tracks are extended out) and will dig to 1,800mm depth. Twin gear pumps provide oil flow to the servo controls, and all pipes are enclosed within the boom to reduce damage. The non zero swing K008-3 narrows down to 700mm and extends out to 860mm when allowable. Featuring the same 10hp engine, the K008-3 weighs just 850kg.

Next in the popular 1.5 tonne sector are the U15-3 and KX36-3. Both machines feature minimum width of 990mm, with the U15-3’s variable track adjusting out to 1,240mm. Boom cylinder on both machines is above the boom to reduce the chance of damage and hoses are routed through the arm for maximum protection. Twin variable gear pumps provide oil flow. The 1.6/1.7 tonne KX41-3S and KX41-3V models both feature a 16hp engine and same hydraulic system; the V version having a variable track width feature that allows a minimum width of 990mm and a maximum of 1,300mm when extended out. These machines are available with the Kubota Intelligent Control System, which includes warning indicators for a variety of functions, service mode and engine hours, rpm, etc. Two-speed travel control is activated by a button the dozer lever, falling to hand where you are most likely to use this function and tidying the floor area say Kubota.

In the same 2.2 tonne-2.5 tonne class, Kubota offer the U20-3α and U25-3α plus the KX61-3 model. The U series machines feature Kubota’s Anti-Theft system as standard that is designed to prevent unlawful use through via a programmed key system. A digital display panel is provided to show diagnostic and operational information. The U20-3α model is equipped with variable track from 1,300 to 1,500mm. The KX61-3 model weighs in at 2.5 tonnes and is powered by a 25hp Kubota engine. A fixed overall width of 1,400mm is standard with no extension facility and the control centre features the digital display system also. Three more zero swing models fall into the 3.5 to 5 tonne sector. The U35-3α2 is a 3.5 tonne, 27.5hp machine featuring adjustable oil flow to the auxiliary circuit via a thumb operated proportional push switch, anti-theft system and auto idling. This activates if levers are inactive for four seconds or more, sending the engine to idle. When the levers are moved, the revs are put back to their preset level, set by a dial on the operator console. A hydraulic breaker switch is also fitted to the right hand control lever for ease of use. The slightly larger U45-3α and U50-3α are equipped with similar features to the 3.5 tonne machine but with a 40hp engine.

In the same class, the non-zero swing offering includes the KX91-3α2 and KX101-3α2 (at 3.2 and 3.5 tonnes), KX121-3α2 (3.9 tonnes) and KX161-3α2 at 5 tonnes. All machines offer similar specifications to their zero swing cousins including features such as the anti-theft system, digital display and auto idle. Kubota engines ranging from 26.6hp (K91) up to 40hp (KX161) power this sector.

Topping the Kubota range is the KX080-3 8 tonner which features auto idle, a “tight” tail swing, anti theft system and electric re-fueling pump with auto cut off. A 65hp Kubota engine provides the power.

CATERPILLAR

US giant Caterpillar has a large range of mini machines from 1.6 to 8 tonnes in weight. Their lineup starts with the 301.6C and 301.8C models. These cover 1.6 and 1.7 tonnes (with canopy) and are both powered by a 19hp Mitsubishi engine. Triple pumps (one gear, two piston) power the hydraulic system, and the larger model features a hydraulically adjustable undercarriage from 980 to 1,340mm. A large rear door offers access to the engine for daily checks.

In the plus 2.5 tonne sector, Caterpillar offer the 302.5C, 303C CR and 303.5C CR which weigh in at 2.7, 3.2 and 3.5 tonnes respectively (with canopies). Powering these models are 25, 31 and 40hp Mitsubishi engines, turbocharged on the largest machine. The CR designation on the larger models means compact radius, so offering reduced swing characteristics say Caterpillar. The 304C CR and 305C CR models fit into the 4.5 to 5.1 tonne sector, and feature compact radius configuration, Mitsubishi engines from 37 to 50hp and differing hydraulic systems – The fairly new 304C CR has a single variable displacement piston pump with the 305C CR using the same single piston pump but to a higher flow level. A cab can be specified on both models.

Topping the mini/midi range from Caterpillar are the 307C and 308C CR models. The 307C model weighs in at either 7.2 or 8.4 tonnes, depending on the specification as the machine can either be ordered with a standard fixed arm or optional swing boom. Powered by a MMC (Mitsubishi) 55hp engine, the 307C has steel tracks as standard, with rubber shoes optional should they be required for more delicate areas. The optional swing boom is designed for closer working to walls and obstructions and can offset to 60 degrees left and 69 degrees right. The 308C CR features a 55hp engine and operating weight of 8,040kg. The machine is a compact radius version of the 307C and has been designed to operate within a 3,000mm wide envelope. Depending on chosen track width, operating overhang can be down to as little as 55mm. Two stick lengths are available for the 308C CR allowing varying digging depths and capacities to be achieved.

KOMATSU

Komatsu’s range covers from an 880kg machine up to a 7.5 tonne model. The PC09-1 and PC09H-1 Micro machines start off the range. Both feature variable undercarriage, with minimum width from 700mm for access through standard doors. The PC09H-1 has a built in hammer tool in place of the standard dipper of the PC09-1 and this adds some 100kg to the standard machine weight. TOPS canopy is available as an extra and lift up rear seat/engine cover aids maintenance. An 8.5hp Komatsu engine powers both models.

Next up is the PC14R-2, which is available in four different specifications: with cab or canopy, and with or without variable undercarriage. Therefore, operating weights range from 1.46 to 1.75 tonnes, so this may be a consideration on purchase. Featuring a tilting floor and wide opening panels, access to the 14.5hp Komatsu engine and hydraulics are simple, and this applies to all mini models from the PC14R-2 upwards. Variable track machines can narrow down to 980mm and increase up to 1,300mm for stability when required, so ideal when access is a problem plus ideal for transport. A single gear pump provides the flow to the CLSS (closed-centre load sensing system) for smooth and precise control say Komatsu.

The minimal turn PC18MR-2 is next in the range, and is only available with variable undercarriage but with cab or canopy. Variable undercarriage is from a minimum of 980mm up to 1,300mm, as per the PC14R-2 machine. A 15hp engine drives a single piston pump and the CLSS hydraulics. Topping 2 tonnes is the PC20MR-2, again a minimal turn machine but with fixed undercarriage and either cab or canopy. Short tail compactness is the PC20MR-2’s main feature, plus an optional long arm aids in digging capability and PPC proportional controls aid operator ergonomics level. A fixed width of less than 1,500mm allows good access potential for landscapers and builders alike. Next up in the range is the PC27MR-2, topping just a shade over 3 tonnes in its standard guise. Similar in all but capacity to the PC20MR-2, this model is generally only sold in the UK with a cab, although Komatsu say a canopy type can be ordered if so required.

The PC30MR-2, PC35MR-2 and PC50MR-2 models weigh in at 3.4, 3.8 and 5.1 tonnes respectively and feature CLLS hydraulics with a variety of pump configurations. All models can be fitted with extra counterweights which removes the zero swing capability to minimal swing but adds stability.

Topping the sub 8 tonne range is the PC75R-2 Utility model. A 68hp Komatsu engine and CLSS hydraulics with “power” and “economy” modes are standard as are PPC proportional controls. The machine is available with either a mono or two-piece boom depending on requirements. With all utility models from Komatsu, steel tracks are an option although the company says 95% are delivered on rubber boots.

BOBCAT

Bobcat offer a wide range of machines up to 8 tonne, including a micro machine and a 3.5 tonner with extending dipper. The range starts with the micro 316 model, just 700mm wide at narrowest track setting (extendable up to 900mm) and weighing in at 820kg. Kubota provide a 10hp engine to power the twin gear pump hydraulics system, and a roll over frame is standard.

Moving up slightly, the 319 and 320 models cover the 1.3 to 1.7 tonne sector. Available in cab or canopy guise, the machines are similar bar the 319 having a slightly smaller Kubota engine, two pump system (as opposed to three on the 320) and extendable tracks which can move from 980 to 1,363mm when stability is vital. The 320 features a twin travel speed facility and the 319 has its boom cylinder above to protect from damage. Fitting in just above these models are the 321 and 323 models, which feature a 13hp engine, triple pump hydraulics and extendable tracks (from 980 to 1,360mm). The 321 has a shorter dipper arm than the 323 and is a tad lighter at 1,605kg (with cab) or 1,476kg with canopy.

Weighing 2.8 and 2.9 tonnes respectively, the Bobcat 325 and 328 excavators are almost identical machines apart from the 328 having a longer dipper that enables a maximum dig depth of 2,859mm. A 27hp Kubota engine powers both machines and twin piston pumps with extra gear unit provide oil flow to the control system. Into the plus 3 tonne sector and Bobcat offer the 3.3 tonne 329/331 and 3.5 tonne 331E models. The 329 has a 27hp engine, 1,540mm fixed track undercarriage and 3,100mm dig depth. The 331 and 331E both feature a 40hp engine, twin piston pumps and optional cab with heater. The 331E also boasts an extendable dipper arm, giving an extra reach when a conventional machine is not enough but size and weight is an issue. These plus the entire range of larger Bobcats feature load sensing hydraulics too.

The 334 and recently introduced 335 model weigh in at 3.4 and 4.2 tonnes respectively. Both feature a 40hp engine, the 334 fitted with a dual piston pump setup and the 335 with a single variable displacement unit offering 108 l/minute to the main system and 75 l/minute to attachments. A longer dipper arm is available on the 335 too. Five tonne users can choose from the 337 or 341 machines. Both have a 50hp Kubota engine and a single pump pushing out 177.5 l/minute. Cab or canopy can be specified.

Into zero swing territory and Bobcat offer five models in 2.6, 2.9, 3.5, 5 and 7.5 tonne variants. The company claim 320 degrees of zero swing due to the fact that the rear as well as the front corners of their machines is within the machine track width. The 2.6 tonne 425 and 2.9 tonne 428 both utilise a 27.5hp Kubota engine. The 425 has a 2,541mm digging depth and a width of 1,540mm. The 428 features the same width as the 425 but will dig to 2,844mm. A transverse engine mounting is said to ensure easy access, via a swing up rear hatch. The 3.5 tonne 430 is available in standard or what Bobcat call “FastTrack” versions, which means tracking can be up to 8kph in high range. The 430 is powered by a 42.5hp engine and this drives a twin piston plus one gear pump hydraulic system. Optional long arm gives an extra 300mm digging depth over the standard type.

The 435, at 5 tonnes, has a slightly larger engine (49hp) and features a load sensing piston pump and external gear type too. FastTrack model can track up to 8.7kph around sites. Long arm option is available, offering over 300mm extra digging depth. Topping the sub 8 tonne range from Bobcat is the zero swing 442 model. A claimed zero swing radius of 240 degrees allows close up working to buildings and circular boom option allows for even tighter turning radius and increased dig depth. Operators have an information panel to their right hand side inside the standard cab.

TEREX

Terex offer a selection of mini and midi machines to the UK market. They range from 1.5 to a shade under 8 tonnes. The mini range kicks off with the 1.5 tonne TC15 which features an 18hp Mitsubishi engine, dual fixed displacement pump and Knickmatik lateral boom adjustment system, which offers 60 degrees boom swing to the left and right. Almost identical is the TC16 model, which features a cab as standard as opposed to a canopy and weighs in at a shade over 1.7 tonnes. The TC16 also has adjustable track width, variable from 990 to 1,340mm. Again similar in spec as its smaller brothers but weighing in at 1.95 tonnes is the TC20 model. This offers the same engine and extendable track system as well as standard cab.

Recently launched is the 2.5 tonne TC25 model. This comes with a 1,400mm dipper (for UK only), 24hp Mitsubishi engine and 67 l/minute load sensing pump. With a dig depth of 3,060mm, the TC25 features a manual quick hitch (as with all Terex excavators) and the company’s Knickmatik boom system, allowing 710mm offset right and 510mm offset left to combine with the machine’s zero swing capabilities. A full width dozer blade is also standard.

Moving to above 2.5 tonnes, Terex offer the 2.85 tonne TC29 model which features a 26hp Mitsubishi engine and load sensing variable displacement pump, plus cab. For 3.5 tonne users, the TC35 is the Terex model that fits the bill. Featuring a 32.5hp engine, the TC35 also boasts a similar load sensing hydraulic system and cab to the TC29. This model’s dozer blade is available in standard and extra long versions too.

The TC37 features the same 32.5hp engine as the TC35 model but is a near zero swing variant, offering working access to tighter areas. Two dippers are available in 1,600 or 1,800mm lengths. The TC48 is a 4.8 tonne machine featuring a 47hp engine, tandem controlled twin piston pump for working control and travel, a gear pump for swinging and dozer work and another gear pump for pilot pressure. This model features standard or extra long dozer blade option too, plus either a 1,650 or 1,850mm dipper.

Over 5 tonnes, Terex offer the TC50, TC60 and TC75 models that cover the 5 to 7.5 tonne sector. Engines from 40 to 73hp are fitted, the TC75 featuring a Deutz unit rather than Mitsubishi. The TC50 and TC75 use an axial piston variable displacement pump system (TC50 has load sensing system) whilst the TC60 has the tandem controlled twin system from the TC48. The TC75 can be specified with a circular boom for greater versatility.

JCB

JCB’s position as a UK manufacturer of excavators is a fairly lonely one, but the company offers a large choice to those who require their machines compact which can compete with the likes of many a Far East manufacturer.

In micro circles, JCB offer a total of three models, all of which feature extending track undercarriage. The Micro 8008 is built around a 12.7hp engine and twin gear pumps developing 24.4 l/minute. Minimum width of 700mm allows for extension out to 865mm. The Micro model, which can be specified with either an 800 or 950mm long dipper arm, has a minimum width of 700mm but extends out to 1,000mm for stability. It’s slightly larger cousin, the Micro Plus, has the same feature but from 970 to 1,350mm and runs on slightly wider tracks. This model has either a 950 or 1,138mm dipper arm option. Both Micro and Micro Plus models have an 18.4hp engine and twin gear pumps. The Micro weighs in at around 1.1 tonnes whilst the Micro Plus tops the scales at 1.28 tonnes. TOPS frame is standard on all Micro machines.

The 1.5 tonne sector is catered for by 8014 model, which features a 17.7hp engine, 980mm width fixed undercarriage and triple gear pumps. Cab is optional to replace the standard ROPS and TOPS canopy. Slightly larger are the 8016 and 8018 models, which weigh in 1.6 and 1.66 tonnes respectively. Both machines have a 19hp engine but the 8018 features extendable track undercarriage from 980 to 1,340mm with the 8016 having a fixed system at 972mm width. Standard hydraulics are a triple gear type with optional variable displacement system featuring one variable and one gear pump should it be required.

Newly introduced in January is the 8020 model, weighing at 2 tonnes. The 8020 has been designed the requirements of those who require an excavator to be towed behind twin cab pickups, but find that larger machines make this illegal due to weight restrictions. The 2 tonne weight allows this say JCB, depending on towing vehicle and trailer. The 8020 features reduced tailswing, a 2,400mm dig depth and 19kN bucket tearout force.

When 2.5 and 3 tonne machines are specified, JCB offer the 8025ZTS and 8030ZTS models, which are as one would expect by their name, near Zero Swing machines. Both have 27hp engines and twin variable/single gear hydraulic system and a canopy is standard, with cab an option. The 8030ZTS has a 1,300mm dipper compared to the 8025’s 1,100mm too. A neat feature of the ZTS machines is that there is only one right hand extra foot pedal (apart from travel pedals) to operate boom offset or hydraulic auxiliary service. A switch on the control joystick switches between the two. The 3.5 tonne sector is serviced by the 3.65 tonne/30.4hp 8035ZTS model. A ROPS/TOPS canopy is standard as is a 1,525mm dipper arm for a maximum dig depth of 3,512mm. Again, twin variable and single gear pump provide the oil flow.

At 4.3 and 4.75 tonnes are the 8040ZTS and 8045ZTS versions, both equipped with a 45hp engine. A load sensing variable displacement pump system is installed on both machines and these deliver 169 l/minute to the digging and travel functions. Both feature a floor mounted offset pedal to alleviate removing hands from the controls. Weighing in at 5.28 and 5.3 tonnes respectively, the new 8055ZTS and 8055RTS are based on the 8045 model. With zero (ZTS) and reduced (RTS) tail swing, both machines build on the company’s history of machines in the 5 to 6 tonne sector which began with the 8052 in 1999. Both machines feature an Isuzu 3 cylinder engine, and offer 5.5 kph tracking speed and 3,760mm maximum dig depth.

At 5.2 and 6 tonnnes, models 8052 (due to be replaced by the 8055 model later in 2008) and 8060 are what JCB define as minimal tailswing, so overhang from the counterweight is cut to the minimum that it can be, but not completely removed. Powered by 48 and 60hp engines respectively, the 8052 and 8060 models feature a variable displacement load sensing Rexroth pump. The 8060 has two dipper length options of 1,500 or 1,900mm.

Topping the compact range is the 8080ZTS machine. Packing a 58hp engine and single variable displacement pump, the 8080ZTS has a cab that JCB claim is a full size type offering high comfort which is unlike many zero swing machines. The machine also has the company’s AMS (Advanced Management System) which provides an in cab monitor showing information such as fuel level, engine water and oil temperature plus diagnostics and service interval indicator. This feature also offers three digging modes.

DOOSAN

Doosan offer a good selection of machines in the sub 8 tonne sector. They kick off with the Solar 015 Plus machine, which at 1.57 tonnes is the bread and butter machine of any range. A Mitsubishi 17hp engine powers the 015 via twin variable rate piston pumps. A 1,690mm boom and 1,100mm arm are standard, with a 75/50 degree left/right slew angle and dig depth down to 2,385mm. For those needing a little more weight, the 1.74 tonne (with cab) Solar 018VT offers variable track width from 980 to 1,300mm making the machine ideal for narrow access areas. A maximum dig depth of 2,325mm is via the same boom setup as the Solar 015. It also has an identical engine and hydraulics package to this machine.

Jumping up to sub 3 tonnes, the Solar 030 Plus features an Isuzu 24.5hp engine, 66 l/minute twin pump hydraulics and maximum digging depth of 2,799mm. Available with a cab or canopy, the 030 is standard with 300mm rubber tracks and an 80/50 left/right boom slew angle. Over 3 tonnes, Doosan’s Solar 035 offers the same engine as the 030 model but with an extra 8 l/minute oil flow. Again, cab or canopy can be specified and digging depth is up to a healthy 3,383mm with a 2,500mm boom and 1,500mm arm.

Topping 5 tonnes are the Solar 55v Plus and Solar 75v models. The former, at 5.5 tonnes, has a 52hp Yanmar engine with its larger cousin featuring a similar power with a different Yanmar unit. The 55v has 110 l/minute on tap and can dig to 3,796mm with its 3,000mm boom and 1,600mm arm. The 8 tonne 75v on the other hand uses a single variable displacement pump rated at 135 l/minute and will dig to 4,420mm depth. Optional arm length of 2,200mm can replace the standard 1,800mm version.

In zero swing circles, Doosan can offer two models, the DX27z and DX35z. The 2.7 tonne DX27z features 21hp engine, tandem axial piston pumps delivering over 50 l/minute and a 2,000mm boom with 1,000mm arm to give a maximum dig depth of 2,490mm. An optional arm of 1,300mm gives an extra 200mm dig depth. The slightly heaver 3.7 tonne DX35z has a 27.7hp engine, triple pump system with 102 l/minute on tap and a maximum dig depth of 3,023mm. An optional arm length of 1,330mm can be specified to replace the standard 1,200mm unit.

HYUNDAI
Hyundai provide several models into the UK mini/midi market, including two zero swing machines. The 1.5 tonne 15-7 model starts off the Hyundai range and comes with a 17hp Mitsubishi engine, triple gear pump with a 45 l/minute output, and choice of cab or canopy. Steel tracks can also be specified as can a longer arm, which can also slew 80 degrees to the left and 50 to the right. The 15-7 is just 1,000mm wide. The 16-7 and 22-7 versions feature the same engine as the 15-7, plus similar boom slew characteristics. The 16-7 runs on the same triple gear pump system while the 22-7 utilises a twin piston/single gear setup. Weighing in at 1.6 and 2.2 tonnes (in basic canopy variant), the smaller 16-7 features extendable track width from 1,000 to 1,300mm with the 22-7 having a fixed 1,380mm configuration.

The 2.8 tonne 28-7 has a 24hp engine, twin piston/single gear hydraulics, cab as standard with canopy option and 1,470mm fixed width. Long arm is optional too. The 3.5 tonne sector is catered for by three Hyundai models – R35-7, R35-7Z and R36N-7. The R35-7 is a 3.3 tonne machine with a 27hp Mitsubishi engine and fixed 1,580mm width track undercarriage. As per the 28-7, canopy is an optional choice. The zero swing R35-7Z and R36N-7 are powered by 27hp Yanmar and Mitsubishi engines respectively and offer 3.5 tonne performance up close to walls and obstacles. The R36N-7 has the triple pump system as found on the smaller models, whereas the R35-7Z is equipped with a twin variable displacement system with gear unit for the pilot circuit. This machine was launched at BAUMA 2007 event.

Hyundai offer one 5.5 tonne machine – the 5.7 tonne 55-7, which features a 53hp Yanmar engine, which Hyundai claim is the largest available in this class of excavator. An offset boom swing angle of 130 degrees is standard as is a twin variable displacement pump hydraulic system. Topping the Hyundai midi range are the 7.5 tonne R75-7 and 7.8 tonne R80-7 models. The R75-7 has a 55.5hp Mitsubishi engine and twin piston/single gear hydraulics. Running on standard or steel tracks, the R75-7 is only available with a cab.
