Light semi-trailer: As the name suggests, ultra-light semi-trailer is a car that is much lighter than ordinary cars. How much lighter is ultra-light? The industry definition is that the car with the same load, size and weight as ordinary cars is defined as ultra-light. There are several ways to make the semi-trailer light:
1. Reduce the thickness of the plate. This can be achieved with steel with a higher grade. High-grade steel has high strength, good toughness and fatigue resistance
2. Reduce the weight of the rear axle. The axle plus the suspension is now close to two tons, and light bridges, disc brakes, 4 leaf springs, new hanging ears, vacuum tires, single tires, etc. are all effective methods
3. Change the suspension. Use airbag suspension, which is less used
4. Reduce the weight of accessories. Reduce the weight of bumpers, side protection nets, mesh spare tire racks, tool boxes, tarpaulin racks, etc.
5. Another way is to use a suspended rear axle, which is what everyone knows. The rear axle can be lifted when not in use. The most common method now is to use high-strength (domestic high-grade) steel to reduce the dead weight. High-strength steel semi-trailers are lighter than ordinary carbon steel light semi-trailers. Using high-strength steel imported from Sweden, the semi-trailer is optimized in design. Without changing the semi-trailer's load capacity, the semi-trailer's weight is reduced by more than 1.3 tons, which can effectively improve the vehicle's use efficiency.
