Where is the Root Cause of Cracking of Side-dump Semi-trailer?
Why does the side dump semi trailer crack? The problem is common, and we think there are two main points:
1. The corporate design considerations of side dump semi trailer are not comprehensive enough, and there are stereotyped thinking
The priority of the side dump semi trailer is of course the load-bearing capacity of the vehicle. However, in addition to the trailer's load-bearing capacity, vehile companies must also seriously consider how to ensure the safe performance of the side dump semi trailer's self-unloading function. The selection of the oil cylinder, the force of the sub-frame and the suspension under different conditions during lifting must be taken into consideration.
The side dump semi trailer hydraulic top bracket carries a large part of the weight of the cargo when it is lifted. The firmness of the bracket and the force of different parts of the frame during lifting must be analyzed and tested, so as to check the leaks and avoid peeping in the tube.
2. It is necessary to improve the welding process of the side dump semi trailer company
The side dump semi trailer is currently still in the development stage. The products on the market are relatively mixed, and the welding process and quality are uneven. In order to reduce costs, some trailer companies occupy the market at low prices, choose non-standard steel, cheap and low-quality accessories, and do not pay much attention to the welding process, which easily leads to product quality problems. The welding process of the side dump semi trailer is not carried out well, and the most typical manifestation is that the weld cracks under stress.
