The engine of the dump truck drives the hydraulic pump through the gearbox and power take-off device. The hydraulic tilting mechanism of the carriage is composed of an oil tank, hydraulic pump, distribution valve, lifting hydraulic cylinder, control valve, and oil pipe. The engine drives the hydraulic pump through the transmission and power take-off device, and high-pressure oil enters the lifting hydraulic cylinder through the distribution valve and oil pipe, pushing the piston rod to tilt the carriage.
