W2500LC (8)

 1. Cummins QSM11 engine features strong power and high fuel economy; Imported Horton electric control silicon oil clutch fan can automatically adjust the fan speed according to system temperature, which reduces energy consumption and reduces noise; Imported fuel pump has empty suction and blocking protection function, which can avoid damage to the fuel pump due to misoperation; Suction valve and drain valve in the fuel tank are optimally positioned, so that the maintenance and water draining of fuel system can be performed without dismantling the bottom cover; Fleetguard 2-in-1 fuel filter has water level warning and fuel heating function; Water radiator also has water level alarm function which can avoid engine overheat due to insufficient coolant; Engine has automatic idling, speed up and overheat protection function, which greatly reduces fuel consumption and protects the engine.

 

 

2. Rexroth negative flow system, automatic speed up and energy saving control technologies are applied, which reduces fuel consumption and improves efficiency.

 

3. Boom, arm and chassis adopt reinforced design with mature structural strength analysis software, which guarantees the designed service life of the structural parts; 2.2m3 large capacity bucket is applicable to heavy duty mining operations; Detachable chassis structure is convenient for transport and adjusting the chassis gauge. 

 

4. Built-in boom and arm holding valves in the main valve can prevent the lowering of boom or arm in a long time; Boom and arm regeneration function can effectively avoid cavitation in the cylinder and reduces fuel consumption; Automatic boost during travel improves the gradeability; travel motor speeds up slowly and starts smoothly, which improves comfort; Automatically or manually improve system pressure by 10% during operation to improve the excavating force; When main pump pressure reaches or approaches the maximal pressure, the system will automatically adjust the main pump flow to reduce energy loss; Main pump power is increased during single slewing operation to reduce energy loss during the start process, and the actuator can provide maximal flow to increase speed, the movement of the control lever enables precise control of cylinder speed and improves comfort operation.
