How Does A Heavy-Duty Dump Truck Work

The working principle of heavy-duty dump trucks is mainly to achieve self-unloading of goods by means of hydraulic system or mechanical lifting.

Specifically, dump trucks usually have a large capacity cargo box for loading various types of cargo. When the cargo needs to be unloaded, the dump truck achieves unloading by changing its structure. The specific way is through the hydraulic system or mechanical lifting mechanism, the carriage is tipped over at a certain Angle, so that the goods are unloaded by themselves. Among them, the hydraulic system is usually composed of hydraulic cylinder, distribution valve, tubing, etc., through the high-pressure oil through the distribution valve, tubing into the lifting hydraulic cylinder, pushing the piston rod to tip the carriage. There are also some dump trucks using mechanical lifting, through the chain or wire rope and other mechanisms to lift the car to the required height.

In addition, the compartment of the dump truck can be tipped backwards or sideways as needed to adapt to different unloading needs. Backward tilting is a more common way, through the control system to control the movement of the piston rod, can stop the carriage in any required tilt position. The side tilting is suitable for some special occasions, such as cargo unloading in small Spaces.

In short, the working principle of heavy-duty dump trucks is mainly through the hydraulic system or mechanical lifting to achieve self-unloading of goods, with efficient and reliable performance, which provides an important guarantee for the smooth completion of various engineering projects.
