How a dump truck works

The structure of the engine, chassis and cab of a dump truck is the same as that of a general truck.

The high-pressure oil enters the lifting hydraulic cylinder through the distribution valve and the oil pipe, and there is a cab safety protection plate at the front end of the carriage.

The engine drives the hydraulic pump through the transmission and the power take-off device. The hydraulic tilting mechanism of the carriage is composed of a fuel tank, a hydraulic pump, a distribution valve, a lifting hydraulic cylinder, a control valve and an oil pipe.

The engine drives the hydraulic pump through the transmission and the power take-off device, and the high-pressure oil enters the lifting hydraulic cylinder through the distribution valve and the oil pipe, and pushes the piston rod to overturn the carriage. Backward tipping is more common, and the movement of the piston rod is controlled by the steering system to stop the carriage in any desired tilted position. The carriage is reset using its own gravity and hydraulic control.
