First, what is the working principle of dump truck
The structure of the engine, chassis and cab of the dump truck is the same as that of the general truck. The compartment of the dump truck is divided into two kinds of backward tipping and lateral tipping. The working principle is through
The control system controls the movement of the living base rod, and backward tipping is common. When the living base rod is pushed, the vehicle tilts phase, and a few two-way tilts. The high pressure oil enters the lifting hydraulic pressure through the distributor and tubing
Cylinder, the front end of the carriage is equipped with cab safety protection plate. The engine drives the hydraulic pump through the transmission and force taking device, and the compartment hydraulic tipping mechanism is composed of oil tank, hydraulic pump, distribution valve,
Lifting hydraulic cylinder, control valve and tubing, etc.
The car hydraulic tipping mechanism is composed of oil tank, hydraulic pump, distribution valve, lifting hydraulic cylinder, control valve and oil pipe.
