What is Dump Semi Trailer?

Dump semi-trailer is equipped with automatic dumping device. Also known as dump truck, construction truck, by the car chassis, hydraulic lifting mechanism, pick-up device and cargo compartment composition

In civil engineering, it often works together with excavator, loader, belt conveyor, etc. to form loading, transporting and unloading production line for loading and transporting earth, gravel and loose materials.

By the dry loading carriage can automatically tilt a certain angle to discharge materials, greatly save unloading time and labor, shorten the transport cycle, improve production efficiency, reduce transport costs, and mark the loading volume. Is commonly used transport machinery.

The structure of engine, chassis and cab is the same as general load car, and the carriage can be tilted backward or sideways, and the live cold rod movement is controlled by the operation system, after which it is more common to tilt backward and push the piston rod to make the carriage tilt. A few two-way tilting. High-pressure oil through the distribution valve, oil pipe into the lifting hydraulic cylinder, the front of the car has a cab safety plate. The carriage hydraulic tipping mechanism consists of oil tank, hydraulic pump, distribution valve, lifting hydraulic cylinder, control valve and oil pipe. Engine through the transmission, take the force device drive hydraulic spring, high pressure oil through the distribution line, oil pipe into the lift hydraulic cylinder, push the piston rod to make the carriage tilt, later to tilt more brag, through the manipulation system control piston rod movement, can make the carriage stop in any required tilt position. The carriage uses its own gravity and hydraulic control to reset.

The main technical parameters of the dump truck are the loading weight and the marked loading volume. New car or overhaul factory car must be test run, so that the carriage lifting process is smooth and no crosstalk. When using each part should be correctly selected according to the provisions of the lubricant, greatly save unloading time and labor, pay attention to the lubrication cycle, lifting mechanism strictly on schedule to change the oil, according to the rated loading capacity of the shipment, overloading is strictly prohibited.
