How 7ton China Wheel Excavators Earth Movers Work

Author:

7ton China Wheel Excavators Earth Movers are driven by wheels, use buckets to excavate materials above or below the bearing surface, and load them into transport vehicles or unload them to stockyards. Commonly used in small and medium-sized engineering construction.

7ton China Wheel Excavators Earth Movers

7ton China Wheel Excavators Earth Movers is driven by a diesel engine or an electric motor to drive two main hydraulic pumps to generate high-pressure oil and send it to the multi-way valve, which is controlled by the pilot control valve and sent to the relevant hydraulic actuators (hydraulic cylinder or hydraulic motor, etc.) through the multi-way valve. , to drive the corresponding mechanism to work. In the working process of general working devices, more than two compound actions and the confluence of boom and stick actions are often required to make full use of the engine power and shorten the working cycle time. The travel of 7ton China Wheel Excavators Earth Movers generally adopts hydraulic-mechanical transmission, that is, high-pressure oil directly drives the gearbox from the central rotary body to the travel hydraulic motor, and then drives the vehicle to travel through the transmission shaft and drive axle. The walking speed of the wheel excavator is generally divided into high and low gears, the low gear is the walking speed during work, and the high gear is the road walking speed.
