howo 8×4 dump truck the structure of the dump truck’s engine, chassis and cab 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 guard plate at the front of the carriage.

The engine drives the hydraulic pump through a transmission and a power take-off device. The hydraulic tilting mechanism of the carriage is composed of an oil 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 cause the carriage to tip over. Backward tipping is more common, and the movement of the piston rod is controlled by the control system to stop the carriage at any required tilt position. The carriage uses its own gravity and hydraulic control to reset.
