Self-dumping semi-trailer refers to the semi-trailer that can automatically tip over at a certain Angle when unloading, and its market coverage is relatively high. With the advantages of transportation efficiency and transportation cycle, it plays an irreplaceable role in the transportation of loose goods such as sand and gravel, soil and coal.
Compared with ordinary semi-trailers, the use of Dump Semi-Trailers is more complex, if the quality of the product is not up to standard, it is easy to have problems, which are mostly cracking.
The specific performance of the cracking of the dump truck:
1.Weld cracks at the flipping beam and web
In the process of using the Dump Semi Trailer, the torque is relatively large, especially the lower wing plate, and the torque acts on the flip beam through the tilt brace, resulting in great stress at the welding place between the flip beam and the web plate, and the weld is easy to crack.
2.Suspension ribs cracked
Generally speaking, the arc Angle at the variable section change of the suspension rib plate of the self-dumping semi-trailer is small, so the stress is too concentrated. At the same time, due to the existence of weight reduction holes, the strength at the section of the plate rib plate is greatly reduced, so it is easy to break. Especially when the vehicle passes through complex road conditions, the torsion occurs here, and the web will crack.
3.Suspension skew brace and suspension large brace crack
The suspension is the area with large torsion, especially when the frame turns quickly, the lateral force of the tire will act on the frame through the axle, plate spring, suspension, etc., so the moment of the frame is larger, especially at the lower wing plate, it is easier to twist and cause the internal and external support plate to crack.

4.Suspension diagonal brace cracking
The suspension web of some dump semi-trailers is not reinforced with stiffened plate support, and the suspension skew brace is not welded with the connecting pipe. In the process of use, the suspension bears a large torque, and the stress of the skew brace plate is too concentrated, resulting in the suspension skew brace cracking.
5.Subframe flip beam reinforced diagonal brace cracking
There are two reasons for the cracking of the diagonal brace reinforced by the flip beam of the subframe: the longitudinal beam of the subframe is crossed with the flip beam, the strength is weak, and the flip beam will be deformed when the vehicle is flipped and unloaded; If the front and rear cylinders are not synchronized when unloading the dump truck, the subframe is prone to torsion cracking.
As for the reasons for the cracking of the dump truck, the main problem is whether the design is reasonable and the production process is not up to the standard. Car Transport Trailer hire hamilton|Car Transport Trailer Nz|Car Transport Trailers For Sale Uk|Car Transport Trailer Enclosed
