What Is A Dump Truck

A car equipped with an automatic dumping device in the carriage of a dump truck. Also known as a dump truck or engineering vehicle, it consists of a car chassis, hydraulic lifting mechanism, power take-off device, and cargo compartment. In civil engineering, it is often combined with excavators, loaders, belt conveyors, etc. to form a loading, transporting, and unloading production line for the loading, unloading, and transportation of earthwork, sand, and loose materials. Due to the automatic tilting of the loading carriage at a certain angle for unloading, it greatly saves unloading time and labor, shortens transportation cycles, improves production efficiency, reduces transportation costs, and indicates the loading capacity. It is a commonly used transportation machinery. Introduction: The structure of the engine, chassis, and cab is the same as that of ordinary heavy-duty vehicles. The carriage can tilt backwards or sideways, and the movement of the piston rod is controlled by the operating system. Backward tilting is more common, and the piston rod is pushed to tilt the carriage. A few bidirectional tilting. High pressure oil enters the lifting hydraulic cylinder through the distribution valve and oil pipe, and there is a safety guard board in the front of the carriage. The hydraulic tilting mechanism of the carriage is composed of 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. Tilting in the future is more common, and by controlling the piston rod movement through the control system, the carriage can be stopped at any desired tilting position. The carriage is reset using its own gravity and hydraulic control. The main technical parameters of a dump truck are the loading weight and the loading capacity. New or overhauled vehicles must undergo a test run to ensure that the lifting process of the carriage is smooth and without any shaking. When using, lubricating oil should be selected correctly for each part according to regulations, greatly saving unloading time and labor. Pay attention to the lubrication cycle, and the lifting mechanism should strictly replace the oil on schedule. Ship according to the rated loading capacity, and overloading is strictly prohibited.
