          The structure of the dump truck, the chassis and the cab is the same as the general truck. Dump truck car rearward tipping and lateral tipping two, through the control system to control the piston rod movement, backward tipping more common, pushing the piston rod to tilt the car, a few two-way tipping. High pressure oil through the distribution valve, tubing into the lift hydraulic cylinder, the front of the car with a safety cabinet.

          The engine is driven by the transmission and the power unit to drive the hydraulic pump. The hydraulic tipping mechanism consists of the fuel tank, the hydraulic pump, the distribution valve, the lifting hydraulic cylinder, the control valve and the tubing. The hydraulic tipping mechanism is composed of fuel tank, hydraulic pump, distribution valve, lifting hydraulic cylinder, control valve and tubing. The engine through the transmission, take the device to drive the hydraulic pump, high pressure oil through the distribution valve, tubing into the lift hydraulic cylinder, pushing the piston rod to tilt the car. The rearward tipping is more common and the movement of the piston rod is controlled by the operating system so that the carriage can be stopped at any desired tilted position. The car is reset by its own gravity and hydraulic control.

          Consisting of hopper and walking chassis. The hopper is mounted on the front of the treadmill in front of the tire, with the weight of the material in the bucket or the thrust of the hydraulic cylinder. Discharge in different directions, before the turn off the material, rotary discharge, rollover discharge, high fulcrum discharge (discharge height must be) and lift dumping discharge (discharge height can be arbitrarily changed) and so on. In order to adapt to the uneven road, to avoid the material scattered, and to discharge in place accurate, rapid, operational effort, and off-road performance and climbing ability, require dump truck speed can not be too fast (usually the maximum speed of 20 km / Below).

          Drive axle in front (hopper above), the driver's seat in the rear of the dump truck for short-distance transport sand, stone, mortar, brick, concrete and other materials. According to the requirements of different construction operations, the current dump truck is moving in the direction of a multi-purpose machine, can quickly change clothes lifting, bulldozing, loading and other work devices, so that it has a multi-functional, high efficiency characteristics.
