As a special vehicle with a large market share, 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 at a certain angle during unloading, which greatly saves unloading time and labor, shortens transportation cycle and improves production efficiency.

At present, the dump semi-trailer on the market is mainly divided into backward dump and side dump. Which one is applied to cargo transportation with higher safety performance?

Take a brief look at the main differences between a backward tipping semi-trailer and a side tipping semi-trailer:

1. Site requirements: generally, the unloading site of the side dump truck is required to be large, wide and flat, while the back dump truck has no excessive requirements for the width of the site, only needs to be flat and unobstructed, and is relatively free.

2. Model requirements: rollover dump trucks are generally used for heavy-duty vehicles or trailers with cargo compartment length greater than 9.6m, while backward dump trucks are more used for 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 during unloading, but also due to its lifting method, the girder is easy to bear uneven force during unloading; In contrast, the lifting height of the back tipping dump truck is large, and the center of gravity of the vehicle is easy to deviate to the tail during unloading, resulting in head warping, especially when unloading from slope to slope.

If the two forms of dump semi-trailer are not well controlled during unloading, they are prone to instability. However, the rollover dump truck generally needs to be equipped with a shift rod, so this rollover accident can be reduced to a certain extent, but it can not be completely avoided, and it needs to be operated strictly and standardized.

Generally, dump trucks and semi trailers transport heavy goods, so the requirements for vehicle chassis are higher. In particular, the axle assembly is not only the key component of the chassis load-bearing, but also related to the braking, driving and other performance of the vehicle. It must be 100% reliable. There are many axle brands in the market. Which one is worth buying? Darong heavy industry group is the first enterprise in Liangshan to mass produce integrated axles. Up to now, it has accumulated 20 years of experience. It has a 32000 ㎡ standard chemical plant. It has 15 production processes from blanking to assembly. The axle has leading performance in strength, toughness, ductility and fatigue resistance, providing higher safety guarantee for car owners and improving vehicle operation efficiency.
