What is a Semi-Trailer?

A semi-trailer is a trailer whose axle is placed behind the center of gravity of the vehicle (when the vehicle is uniformly loaded) and is equipped with a coupling device that can transmit horizontal and vertical forces to the tractor. Semi-trailers are generally three-axle semi-trailers, and their types are divided into 11-meter warehouse rail semi-trailers, 13-meter warehouse rails, and low-platform semi-trailers. It is a heavy-duty transportation vehicle that is connected to the semi-trailer head by a traction pin.

The semi-trailer with a fence structure design is used in the warehouse-type semi-trailer truck. It is mainly used for the transportation of agricultural and sideline products and other light foam goods. 1. The design process of the vehicle model and fence structure is combined with the user's cargo category, and is reasonably designed to fully reduce the weight of the carriage under the load condition. The structure is simple and applicable and easy to disassemble, which reduces the investment cost for the user and creates more profit value. 2. Frame: a space frame structure made by welding the longitudinal beams and the integral penetrating beams. It can balance the strength, rigidity and toughness of the frame, and has strong bearing capacity without permanent deformation. 3. The series of warehouse grid semi-trailers are all through-beam structure, and the longitudinal beam adopts straight or gooseneck type. The web height is from 400 to 500. The longitudinal beam is welded by automatic submerged arc welding. The frame is shot blasted. The beam penetrates the longitudinal beam and is welded as a whole. 4. Suspension system: The new suspension system is adopted, which has high strength and strong impact resistance; the axle load is balanced and the system rod angle is reasonably designed to reduce the frictional slip distance between the tire and the ground during frequent bumps. , Can effectively reduce tire wear, and at the same time can adjust the tie rod, can adjust the wheelbase, and effectively avoid the phenomenon of tire running-in.

What to Do Daily Maintenance on Semi Trailer?

For semi-trailer maintenance in the summer, we must first notice the problem of anti-skid in the rainy season. In addition to the driver's good driving habits and skills, the maintenance of brakes and tires is also the key to driving safety. Therefore, we must pay attention to maintenance in daily use. Maintenance can be performed as follows.

(1) Body waxing and sealing. The acidic components in rainwater have a strong corrosion effect on automotive coatings. Therefore, in the rainy season, it is best to bring the beauty of the car surface.

(2) Anti-rust of chassis. In addition to paint removal, the chassis is close to the ground and is prone to corrosion, so we must pay attention to vehicle chassis cleaning and anti-rust treatment.

(3) Trailer disinfection. Clean the interior of the vehicle in the rainy season to avoid the harm of various bacteria to the human body.

(4) Check the circuit in time. In the rainy season, the electrical system of the vehicle should be checked frequently to avoid leakage failure.

(5) Regular heating. Turn on the heater to mold inside. When the sun can stop when the sun is exposed to the sun, open the window and let the air convection.

Regular maintenance of the semi-trailer can effectively extend the service life of the semi-trailer and is necessary for safe driving.
