Self-unloading Semi-trailer

Jun 15, 2019

Dump truck compartments are equipped with automatic dumping vehicles. Also known as dump trucks and engineering vehicles, 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 combined with excavators, loaders, belt conveyors, etc. to form loading, unloading and unloading production lines, and to carry out loading and unloading of earthwork, sand and loose materials. 

Since the loading compartment can automatically dump a certain angle of unloading, the discharge time and labor are greatly saved, the transportation cycle is shortened, the production efficiency is improved, the transportation cost is reduced, and the loading volume is indicated. It is a common transportation machine. Introduction: The structure of the engine, chassis and cab is the same as that of a typical truck. The car can be tilted backwards or sideways, and the piston rod movement is controlled by the operating system. It is more common to tilt backwards later, pushing the piston rod to tilt the car. A few two-way dumping. 

The high-pressure oil enters the lifting hydraulic cylinder through the distribution valve and the oil pipe, and the cab safety protection plate is arranged at the front end of the car. The hydraulic tilting mechanism of the compartment is composed of a fuel tank, a hydraulic pump, a distribution valve, a lifting hydraulic cylinder, a control valve and a fuel pipe. The engine drives the hydraulic pump through the transmission and the power take-off device. The high-pressure oil enters the lift hydraulic cylinder through the distribution valve and the oil pipe, and pushes the piston rod to tilt the car. It is more common to tilt over in the future, and the steering of the piston rod can be controlled by the operating system to stop the car at any desired tilt position. 

The cabin is reset using its own gravity and hydraulic control. The main technical parameters of the dump truck are the loading weight and the loading volume. New cars or overhauled factory cars must be commissioned to make the car lift process smooth and seamless. When using, all parts should be properly selected according to the regulations, which greatly saves the discharge time and labor, pay attention to the lubrication cycle, and the lifting mechanism strictly changes the oil in time. Shipped at rated load, overload is strictly prohibited.
