The working principle of dump truck
The high pressure oil enters the lifting hydraulic cylinder through the distributing valve and the oil pipe, and the front of the carriage is provided with a safety guard board for the driver's cab.The engine drives the hydraulic pump through the transmission and the force taking device, and the hydraulic tilting mechanism of the car is composed of an oil tank, a hydraulic pump, an distribution valve, a lifting hydraulic cylinder, a control valve, an oil pipe, etc..
The structure of the engine, chassis and cab of the dump truck is the same as that of a general truck.The dump truck is divided into two kinds: rear tipping and side tipping. The piston rod movement is controlled by the control system, and the backward tilting is more common. The piston rod is pushed to make the car tilting and a few two-way tilting.
The engine drives the hydraulic pump through the transmission and the force taking device, and the high pressure oil enters the lifting hydraulic cylinder through the distributing valve and the oil pipe, and pushes the piston rod to make the car roll over. The tilting of the piston rod is more common, and the carriage can be stopped at any desired tilt position by tilting the piston rod by the operating system. The car uses its own gravity and hydraulic controls to reset it.
