“Some New Despite a difficult market situation in many countries around the world manufacturers have not slowed the pace of new developments. Some new mini excavators and compact loaders are featured on the following pages. Bobcat’s new excavators and compact loader Bobcat has added the new E60 and E80 excavators and T110 compact tracked loader to its extensive range of equipment. The line of Bobcat excavators has been extended with the launch of the E60, which weighs 6t in standard configuration with a ROPS cab and standard dipper stick. The digging force over the bucket is 39.9kN, and the digging force over the dipper stick is 26kN. The maximum digging depth is 3.725m, the maximum dump height 3.94m and the maximum reach at ground level is 6m. The larger 8.4t E80 crawler excavator, which is available with steel or rubber tracks, has a maximum digging depth of 4.15m, dump height of 4.72m and maximum reach is 6.965m. A long dipper stick is available as an option. The low noise and emission levels of the E80 make it suitable for operation in noise sensitive areas. The new 2.3t Bobcat T110 compact tracked loader is only 1.2m wide and less than 2.3m long without attachment. Equipped as standard with rubber tracks it should appeal to a wide variety of users in numerous applications. New 3t class excavators Bobcat has launched a completely new generation of 3t class mini-excavators, the 3.2t E32 conventional tail swing and the 3.5t E35 zero tail swing models. The E32 and E35 mini-excavators combine productivity with the ability to carry out 16 PDi • Is s u e 3 - 2009 • Au g - Se p t jobs with precision and fingertip control. The load sense piston pump and the closed centre valve enable fine metering of hydraulic flow for smooth, precise control of machine functions, while reducing hydraulic noise. The boom and dipper arm cylinders are cushioned to provide a smooth, end-of stroke operation. A thumb-operated boom offset control, located on the left joystick, enables improved control of the boom swing function while providing more floor space for the operator. A new feature is the auto-shift travel motor that allows automatic transition from the low to highspeed range or vice versa. Alternatively the autoshift can be disengaged and the operator can use the switch located on the blade control lever to select the travel speed desired. The undercarriages have sealed, maintenance free track rollers, a top roller and wide sprockets offering high resilience and a long service life. The open design and sloped surfaces of the X-frame undercarriage help prevent the build up of mud and debris. Bobcat launches new Tiltrotator Bobcat has launched a new range of Tiltrotator attachments for its line of excavators. The first of the new Tiltrotators is the TR05 model for use on the 5t Bobcat 435 excavator. According to Bobcat, Tiltrotators are an important development in the market for excavators, which are increasingly being seen as tool carriers capable of much more than simply digging holes. Using the Tiltrotator with the appropriate attachments can provide flexible and cost effective solutions for a wide range of applications not normally undertaken with excavators. To complement the TR05 Tiltrotator, Bobcat is launching a new line of attachments specifically for use with the Tiltrotator. They include two grading buckets, two standard digging buckets, trenching buckets, an asphalt cutter, a ripper attachment and a hydraulic stone grab. As well as tilting attachments up to 40° to the left or the right, the TR05 Tiltrotator can rotate an attachment through 360° in both clockwise and counter clockwise directions. All Tiltrotator functions can be operated simultaneously and proportionately using the joysticks in the excavator cab. The mounting system for the attachment on the Tiltrotator is the standard S40 hydraulic quick coupler. The operator is able to change between non-hydraulic attachments on the Tiltrotator by pressing two switches simultaneously in the cab, without having to leave the seat. New Cat TH514 telehandler The new Cat TH514 telehandler has a load capacity of 5t, lift height of 13.7m and forward reach of 9.2m. Load-sensing, flow-sharing hydraulics allow for all three boom functions to be operated simultaneously and proportionally. The 74.5 kW (101 hp) Cat C4.4 DITAAC mechanical control, turbo charged engine is standard and certified to Stage IIIA (Tier3) emission regulations. As standard, a limited slip differential fitted in the front axle allows the machines to work effectively in tough conditions. A range of Cat work tools extends the versatility of the machines. A high visibility manual IT coupler comes as standard, with the option of a hydraulic quick coupler to allow work tool changes without leaving the cab. The new cab is spacious and the single lever joystick with roller switches is easy to use. An in-cab LCD displays a wide range of information, and the keypad can be used to select various operating modes, including three different steering modes. A Longitudinal Stability Indicator for the machine’s forward stability provides a constant check on load safety with a cutout for the extend and lift down functions. Service access points are conveniently located under the engine cover, and routine daily maintenance is now reduced to checking fluid levels and a walk-around inspection. Hitachi unveils ZX14-3 Hitachi Construction Machinery (Europe) NV has introduced the new ZX14-3 to its Zaxis-3 range of excavators and fills a gap in the 1-2t class mini excavator sector. The ZX14-3 is compact and light and can be transported by trailer. It has a three-cylinder 10.7 kW engine with a larger exhaust to comply with the European Stage III A emission regulations. Performance is enhanced by innovative hydraulics, similar to those found in Hitachi Zaxis medium excavators. The
Minis” new model’s control levers are responsive and allow continuous operation with less fatigue. Noise and vibration are kept to a minimum due to an improved tread pattern on the rubber tracks. tracked New steel loaders Bobcat has launched new steel tracked versions of the T250, T300 and T320, compact tracked loader range as an alternative to the conventional rubber tracked configurations. The steel-tracked versions are claimed to be unique due to their ability to work with over 40 different attachments in a wide variety of applications. They offer alternatives to dedicated crawler dozers, which can only be used for bulldozing applications. All three machines have better turning ability than larger tracked machines. The steel tracks, which are 340 mm wide, offer up to three times the track life of rubber tracks in heavy-duty applications. Compared to the rubber tracked versions, the steel tracked T250, T300 and T320 models have an increase in operating weight of approximately 280kg and provide a 37-45% increase in pushing force across all three models. In addition to excellent traction, the steel tracked machines offer high digging power and good dozing and grading capabilities. The sealed and lubricated track chain has a 50% reduction in internal bushing wear, a quieter operation and lower fuel consumption than the sealed only chain. Other aspects include triple grouser track shoes and the 340mm wide pads provide a good balance between traction and flotation. The angled top plates offer easy cleanout, with an open area around the sprocket and under the top roller. Hitachi’s two new wheel loaders Hitachi has introduced two new wheeled loaders the ZW140 and ZW150 to join the ZW180, ZW220, ZW250 and ZW310 models. Equipped respectively with 96kW and 107kW engines the ZW140 and ZW150 are fitted with hydrostatic transmission. This offers greater mobility when fully loaded, smoother control on gradients and under acceleration and deceleration, the company claims. These benefits are achieved due to the twin-motor system, which allows greater operating efficiency from powerful traction at low speed, to a maximum speed of 39km/h. In addition, the HST system’s speed selector provides a range of four maximum travel speeds to suit the particular requirements of each job. In addition when the first range is selected, the maximum speed can be adjusted to four incremental levels, which increase efficiency and simplify operation in confined spaces. The ZW140 and ZW150’s optimum traction force can also be set to increase efficiency. The new models offer four work modes that can be selected according to the needs of the job and operator preference. The electronic matching control senses the hydraulic pressure and controls traction force, which optimises productivity while keeping tyre wear-and-tear and fuel consumption to a minimum. New 1 to 2t mini-excavators Bobcat continues its excavator development with the launch of the new E14 and E16 mini excavators. Featuring as standard a retractable undercarriage, the E14, equipped with canopy and bucket, has an operating weight of 1.3t and has a maximum digging depth of 2.3m. The E16 is available in two versions. Equipped with canopy and bucket, the E16 base model with fixed undercarriage weighs of just over 1.5t with a maximum digging depth of 2.4m. Equipped with canopy and bucket, the E16 with the optional factory installed retractable undercarriage and long dipper stick has an operating weight of 1.55t and digging depth of 2.6m. High digging performance is enhanced by the stability provided by the dozer blade and the low centre of gravity of the machines. The E14 and E16 models, which utilise the cylinderover-boom design, are powered by a 3-cylinder 9.9 kW Kubota D722 engine. braxx ® high frequency power combined with innovative DURAMANT ® segments exceeds even your high expectations!
