As a special vehicle with a large market share, the dump semi-trailer is widely used in the transportation of loose goods such as sand, soil and coal. Its loading carriage can automatically tip over a certain angle when unloading, which greatly saves unloading time. and labor, shorten the transportation cycle and improve production efficiency.
At present, dump semi-trailers on the market are mainly divided into two types: rear tipping dump semi-trailers and side tipping dump trailers. The main differences are:
1. Site requirements: Under normal circumstances, the dump truck requires that the unloading site be large, wide and flat, while the rear dump truck does not have too many requirements for the width of the site. It only needs to be flat and unobstructed, and it is relatively free. Some.
2. Model requirements: Rollover dump trucks are generally used in heavy-duty vehicles or trailers with a length of more than 9.6 meters, while rear dump trucks are more commonly used in standard-load or short-wheelbase vehicles.
3. Lifting form: The lifting height of the rollover dump truck is low, so the center of gravity of the body is relatively low when unloading, but also due to its lifting method, the beam is easily subjected to uneven force when unloading; The lift height of the tipper dump truck is relatively large, and the center of gravity of the vehicle tends to be inclined to the rear when unloading, causing the head to be tilted, especially when unloading from a slope to a slope.
If the two types of dump semi-trailers are not well controlled when unloading, they are prone to instability. However, the rollover dump truck generally needs to be equipped with a shift rod, so this kind of rollover accident can be reduced to a certain extent, but it cannot be completely avoided, and it needs to be operated strictly and standardized.
