1. Start by checking the semi-trailer frame.

We need to check whether the vertical plate of the main beam is perpendicular to the core plate, because the skeleton semi-trailer is mainly a semi-trailer that pulls containers. After the container is loaded, if the vertical plate is not vertical, the contact area of the container will be incomplete, and the container will be broken or damaged.

2. Check and analyze the basic skeleton semi-trailer's large scale.

The large scale of the skeleton semi-trailer is the welding technology method adopted by the enterprise to break the scale. We can use a 14*14 square steel bar for a general scale. The break needs to be fully welded, and the weld must be thick enough.

3. Check the electrical circuit.

Skeleton semi-trailers are different from ordinary semi-trailers. There is no floor on them, so the wires and air pipes are leaked to the outside. It is easy to be oxidized by wind and sun. The skeleton semi-trailers we make generally use all-copper wires and put cable tubes outside. Effectively prevent wire oxidation. Or the damage of wires and air pipes when repairing semi-trailers.
