Dump truck manufacturers tell you what dump trucks are and their characteristics:
Dump trucks are composed of hydraulic systems and operating systems. The lifting oil cylinder is generally a double cylinder. Carbon steel is used for steel plates. The dump truck’s dumping mechanism adopts a forward push-amplification structure, a front single cylinder and a middle double cylinder structure, which is stable and easy to operate. The dump truck’s rear dumping cargo compartment is a full metal structure with rear doors or five doors, three doors, a ship-shaped engineering bucket, and a fence. The dump truck’s compartment can be turned over by itself to unload the items in the compartment. The working cycle time for a turn is ≤60S. The dump truck is suitable for loading and unloading a large number of items. It can cooperate with loaders to work together to transport a large number of ore, sand, gravel, earthwork, etc., which fully improves the transportation capacity of the vehicle.
A car with an automatic dumping device in the compartment. Also known as a dump truck or an engineering vehicle, it consists of a car chassis, a hydraulic lifting mechanism, a power take-off device and a cargo compartment. In civil engineering, it is often used in conjunction with excavators, loaders, belt conveyors, etc. to form a loading, transporting and unloading production line for loading and unloading earth, sand and gravel, and loose materials. Since the loading compartment can automatically tip over at a certain angle to unload, it greatly saves unloading time and labor, shortens the transportation cycle, improves production efficiency, reduces transportation costs, and indicates the loading volume. It is a commonly used transportation machinery.
The structure of the engine, chassis and cab is the same as that of a general truck. The compartment can tip backward or sideways, and the piston rod movement is controlled by the operating system. Backward tipping is more common, and the piston rod is pushed to tip the compartment. A few two-way tipping. The pressure oil enters the lifting hydraulic cylinder through the distribution valve and oil pipe, and there is a cab protection plate at the front end of the compartment. The engine drives the hydraulic pump through the transmission and the power take-off device. The hydraulic tipping mechanism of the compartment consists of a fuel tank, a hydraulic pump, a distribution valve, a lifting hydraulic cylinder, a control valve and an oil pipe. Backward tipping is more common. By controlling the movement of the piston rod through the operating system, the car body can be stopped at any desired tilting position. The car body uses its own gravity and hydraulic control to reset.
The main technical parameters of the dump truck are the loading weight, and the loading volume is indicated. New cars or overhauled cars must be tested to ensure that the lifting process of the car body is smooth and without string movement. When using, all parts should be properly selected according to regulations to greatly save unloading time and labor. Pay attention to the lubrication cycle, and the lifting mechanism should strictly change the oil on schedule. Ship according to the rated load, and it is strictly forbidden to load.
