What’s a sidewall semi trailer ?

The sidewall semi-trailer is a new type of semi-trailer dump truck in China in recent years. Compared with dump trucks, semi-trailer dump trucks have a larger carrying capacity, lower transportation costs, and are more suitable for long-distance transportation. Compared with semi-trailers, they have added a self-unloading function, reduced the labor intensity of workers, and improved loading and unloading efficiency, so they have been widely recognized by market users. They have a fairly broad market and good development prospects.

Advantages and features of starway sidewall semi-trailer :

Rollover semi-trailers are mostly used to transport bulk granular goods such as building materials, ore and coal. Rollover semi-trailers
1. Not only does it have the advantage of stable transportation conditions
2. It can also greatly improve transportation efficiency and loading and unloading efficiency.
3. When unloading, you can tilt one side of the car and open the door to start unloading, which can greatly shorten the unloading time and improve the efficiency of unloading operations.
4. At the same time, the rollover semi-trailer has the advantage of multi-point dispersed force, and the force condition is better.
5. At the same time, the lifting cylinder stroke of the rollover semi-trailer is not large during unloading operations, so it can perform two-way side-tilting unloading operations, which has the advantages of convenience and flexibility.
So at present, rollover semi-trailers have been widely used in transportation.

Working principle of sidewall semi-trailer

The structural design principle of the sidewall semi-trailer is to equip the bottom of the car with multiple lifting structures. During operation, all hydraulic cylinders act on the bottom support of the car together to flip the box to both sides for cargo tilting. By changing the flip pins connecting the two sides of the bottom of the box, the box can be tipped to both sides for unloading. This lifting structure has a very good working effect for semi-trailers with longer car bodies.

The control factors for unloading a sidewall semi-trailer should be as follows :

1. Users cannot adjust the overflow pressure of the overflow valve of the hydraulic system at will to avoid overloading;
2. The vehicle should be parked on a solid and flat road to avoid height difference between the left and right tires;
3. Users cannot install the rear box plate locking mechanism at will;
4. The unloading site must be inspected to understand the actual situation. For vehicles equipped with the rear box plate locking mechanism, special attention must be paid to release it before unloading;
5. When you feel that there is a rollover phenomenon, do not panic, and do not switch the control valve to the car body lowering position, because the car body falls by its own weight, and such operation will create greater danger.
