GENERAL INFORMATION

Specifications are subject to change. Numbers may be rounded.

OPERATING WEIGHT: 25,700 kgBUCKET CAPACITY: 1.2 m³
ENGINE MODEL: Cummins QSB6.7RATED POWER: 142 kW / 2,000 rpm
TRAVEL SPEED: 6 km / 4 hGRADEABILITY: 70%
FEATURES
ENERGY-EFFICIENT & ENVIRONMENTALLY FRIENDLY

Engine: imported Cummins engine which meets the EPA Tier4F emission regulation. Nitrogen oxides and particle emissions are decreased by 90% comparing with Tier3. It is energy-efficient and environmentally friendly, has strong power and low fuel consumption; optimized system matching ensures full play of the overall performance of the complete machine.

Hydraulic system: high-end hydraulic parts have guaranteed product quality, reasonable matching can make the machine provide excellent performance

EFFICIENT PERFORMANCE

Control system: Three kinds of power mode can satisfy requirements of different working conditions; wiring of the control­ler is more simple, convenient and reliable; with optimized functions, the control system has higher efficiency and lower fuel consumption.

Cooling system: It adopts a series-parallel designed radiator that provides smooth airflow and a high flow rate. With good heat dissipation effect, the system can operate stably and has longer service life. The radiator is equipped with a silicone oil clutch fan of which the rotational speed can be controlled and monitored in real-time, thus reducing the noise and decreasing fuel consumption by 3%-5%.

Air filter system: It adopts a pre-filtration and high-performance straight flow air filter to improve air management. By using a straight airflow path creatively, the dust capacity is improved, so that the service life of the filter is extended and the maintenance period is also extended. As a result, the replacement cycle of filter is decreased and overall maintenance cost is reduced.

Safety features: Middle-position startup function can avoid misoperation; standard equipped rear video function which improves operation safety; the monitor which will give an audible and visual alarm when a fault occurs; running alarm function.

CONVENIENT MAINTENANCE

Reliable fuel filtering system: it adopts latest fuel filter, which improves filtering performance, guarantees the quality of intake oil and improves operation reliability of the engine under severe working condition; the filter locates at right door side, which makes it convenient for daily maintenance and filter element replacement

RELIABLE & DURABLE CONTROL SYSTEM

Combined armrest: new type combined armrest has high strength so that breakage of armrest after long term service can be effectively solved. The chassis adopts a strengthened X type cross beam structure so that the strength of cross-section is improved, the durability of the complete machine is good and the service life is extended. Finite element analysis is conducted for structural parts and key parts adopt strengthened design according to load-bearing conditions, thus ensuring the durability under various and high intensity works. Maintenance of fuel filter, engine oil filter, pilot filter, as well as the water tank and electric devices can be conducted directly on the ground.

COMFORTABLE & SAFE

Cab safety: The cab adopts an enclosed structure with high strength, which improves its overall strength and rigidity. Besides, optional falling objects protective structure greatly improves safety.

Shock absorption: Liquid seal vibration isolation rubber is used, which further reduces vibration and noise in the cab, thus helping operators relieve fatigue.

Spacious driving space: Brand new cab with larger space. Such a cab can provide a cozy working environment for operators. Footrests are also improved, so that operation can be more comfortable and easy.

New suspended seat design: The seat is designed on the basis of ergonomics, which can greatly improve the comfortable feeling. The suspended airbag can adjust the height of the seat according to the weight of the operator, thus providing more comfortable operating experiences.

AC system: Imported AC with high capacity. It adopts complete automatic control. It can adjust the temperature inside the cab automatically according to sensors to ensure rapid heating and cooling.

Electronic monitoring system: Embedded installation, which looks more beautiful and elegant.Large 7-inch color display screen which has higher resolution and larger viewing angle. The display interface is optimized, and the display style matches with the application environment at a better level. One key fault inquiry function is provided and makes operation more convenient. More monitoring information ensures better operation of the machine.
