The stability of a dump truck when unloading the cargo means that the center of mass of the cargoes and the carriage are transferred to the unloading side when the dump truck is unloaded laterally, and the capacity of the dump truck to maintain the lateral stability.

Due to the change of the center of mass of the goods and carriages, the load on the elastic elements on the unloading side of the dump truck (such as the Baotou North running heavy card parts spring, the Baotou North running heavy truck tire) has been increased, and the load on the other side is reduced. Therefore, the location of the main components and components of the Baotou BEBEN heavy truck fittings is more inclined than the supporting ground. When the dump truck is unloading under the following circumstances, when the carriage is dumped, the additional inclined angle will be further increased relative to the horizontal plane. The result of the comprehensive effect is that the load on the other side of the dump truck is completely unloaded, and the lateral stability is lost and the car turning over is caused.

The use of the dump truck is generally as follows: the dump truck stops in the tilted field and unloaded in the inclined direction; the dump truck is not opened during the lifting process; the dump truck stops at the soft ground and unloaded laterally, the overload wheels fall into the ground; the dump truck dump the compressed or frozen goods.

In order to avoid similar situations, necessary remedial measures should be adopted to enhance the stability of dump trucks. On the structure, the lateral stability of the dump truck can be enhanced by improving the stiffness of the suspension, installing the lateral balance device, or installing the telescopic leg on the side frame.
