Dump truck hydraulic system maintenance

The biggest feature of the dump truck is that its hydraulic system can complete the lifting of the car body. If there is a problem with the hydraulic system, please solve it as soon as possible to avoid more unnecessary problems. 
If there is a problem that the dump truck compartment is difficult to lift, it is likely to be caused by the following reasons: insufficient fuel in the fuel tank, serious blockage of the fuel tank filter or pipeline, a failure of the fuel pump and no fuel supply, and a blocked lift switch , High-pressure oil pump leakage, insufficient air pressure in the outlet cylinder, poor operation of the power take-off or oil pump gear, and unclean hydraulic oil causing the distribution valve to be stuck.
