Dump trailer accidents occur frequently, and cracking is not uncommon！
Since the dump semi-trailer is often transported with heavy loads, and the cargo box needs to be lifted when unloading, it is easy to cause the center of gravity to be unstable. Therefore, when searching for related accidents on the Internet, you can see many painful cases.
Careful observation of these cases will reveal that in addition to the human factors of overloading, partial loading, and uneven unloading roads, the production quality of trailers is also a very common cause of accidents. For example, in February 2019, a card friend had a problem with the screw quality of the hydraulic base of the vehicle, which caused the hydraulic cylinder to fall off during unloading, and eventually rolled over unfortunately.
In addition, the cracking of the sub-frame, diagonal braces, etc. of the dump semi-trailer is not more common. If these quality problems are not found in time, it is likely to cause accidents during unloading, causing great damage.
Pay attention to structure and welders, don't be cheap！
Based on years of experience, Shanghai Trailer concluded that there are two main reasons for the cracking of dump semi-trailers: one is the unreasonable structural design, and the other is that the production process is not up to standard.
In terms of structure, the rollover dump semi-trailers of most trailer factories in the industry are directly applied to the design of ordinary fence semi-trailers. But in fact, due to the rollover function of this type of vehicle, the force on the subframe, diagonal braces, etc. is much more complicated than that of the fence car.
In response to the cracking of the suspension strut, Shanghai Trailer self-unloading semi-hanger changed the suspension strut to a straight style to increase the rigidity of the suspension.
In terms of technology, since many of the current tipper semi-trailers are products of small manufacturers, the welding process and materials are uneven. In order to lower prices to meet the market, the phenomenon of cutting corners occurs from time to time.
Therefore, when purchasing a dump semi-trailer, it is necessary to focus on several key stress points such as diagonal braces, suspension ribs, and sub-frames. Shanghai trailer Heavy Industry's dump trailers often reinforce these places. Welders, materials and other aspects are also more particular.
dump truck is very important for driving safety. Therefore, when purchasing a vehicle, you must not be greedy for cheapness. You should pay more attention to the structure, workmanship and quality of the parts and components of the product. More durable trailers.
