How to identify the quality of skeleton transport semi-trailer?

How to identify the quality of skeleton transport semi-trailers? When we customize skeleton semi-trailers, it is very important to correctly check the quality of the semi-trailers. From which aspects should we identify?

1. First of all, we should start with the beam of the skeleton semi-trailer.
   We need to see whether the vertical plate of the beam is vertical 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 not be comprehensive, resulting in the container breaking or damage.
2. Check the large scale of the skeleton semi-trailer.
   The large scale of the skeleton semi-trailer adopts the welding method of the broken scale. We use 14*14 squares for general weighing. The broken scale needs to be fully welded, and the weld should be thick enough.
3. Check the electrical circuit.
   The skeleton semi-trailer is different from the ordinary semi-trailer. There is no bottom plate on it, so the wires and air pipes are exposed outside. It is easy to oxidize after being exposed to wind and sun. The skeleton semi-trailers we make generally use all-copper wires, and wire tubes are placed outside. Effectively prevent the oxidation of wires. Or when repairing a semi-trailer, damage to the wires and air pipes.

When we use a low-bed semi-trailer, we need to handle the brakes. If we don’t check, it will cause brake failure. Here’s how to handle the brakes of a low-bed semi-trailer.

1. The water from the sprinkler can’t reach the brake pads. When the semi-trailer is driving at high speed, if there is a situation that requires braking measures, if the water from the sprinkler can’t reach the brake pads, then there will be a loud noise when braking. If this happens, adjust the direction of the water outlet so that the water can be poured onto the sprinkler.
2. The water from the sprinkler can’t flow out, causing the brakes to make noises. In many cases, it may be because the sprinkler water pipe is blocked, causing the water to not be poured onto the brake pads. There is a noise. At this time, we need to clear the water pipe to make the water pipe unobstructed.
3. The brake pad is deformed and the shape of the brake pad is irregular. This is also very common. Sometimes it may be that a piece of the brake pad is damaged, and there is a noise when braking. If the situation is serious, it may cause brake failure or sudden death.
