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

How to identify the quality of the skeleton transport semi-trailer? When we order a skeleton semi-trailer, it is very important to check the quality of the semi-trailer correctly. From what aspects should we identify?

1. First, check from the beam of the skeleton semi-trailer.

We need to check whether the vertical plate of the girder is perpendicular to the core plate, because the skeleton semi-trailer is mainly a semi-trailer that pulls the container. 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 breakage of the container or then damage.

2. Check the scale of the skeleton semi-trailer.

The large scale of the skeleton semi-trailer is a welding method with a broken scale. We use 14*14 squares for general terminology. It is said that full welding is required, and the welding joint must be thick enough.

3. Check the electrical circuit.

The skeleton semi-trailer is different from the ordinary semi-trailer. There is no floor on it, so that the wires and air pipes are leaked 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 there are wired tubes outside. Effectively prevent the oxidation of wires. Or damage to wires and air pipes during maintenance of semi-trailers.

When we use a low-bed semi-trailer, we need to deal with the brakes. If we don’t check it, it will lead to brake failure. Let me explain to you how to deal with the brakes of a low-bed semi-trailer.

1. The water from the sprinkler cannot be poured on the brake pads When the semi-trailer is driving at high speed, if there is a situation where braking measures need to be taken, if the water from the sprinkler cannot be poured on the brake pads, there will be a loud noise when braking. If this happens, adjust the direction of the outlet pipe so that the water can be poured onto the sprinkler.

2. The water from the sprinkler does not flow out, causing the brakes to sound. In many cases, it may be because the water pipe of the sprinkler is blocked, resulting in water not pouring on the brake pads. There is a sound. At this time, we need to pass the irrigation pipe to make the water pipe unblocked.

3. It is also very common that the shape of the brake pad is irregular due to the deformation of the brake pad. Sometimes it may be that a piece of the brake pad is damaged, and there will be a sound when braking. If the situation is serious, it may cause brake failure or sudden death of the brake. Situation happens.
