Working principle of dump truck lifting mechanism

The structure of the dump truck's engine, chassis and cab is the same as that of a general truck.
There are two types of dump trucks: backward tipping and side tipping. Piston rod movement is controlled by the control system. Backward tipping is more common. Pushing the piston rod causes the truck to tip over, and a few have two-way tipping.
The high-pressure oil enters the lifting hydraulic cylinder through the distribution valve and the oil pipe.
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 carriage hydraulic tilting mechanism is composed of oil tank, hydraulic pump, distribution valve, lifting hydraulic cylinder, control valve and 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.
