Description :

　　The definition of semi-trailer is: a trailer that is pulled by a semi-trailer tractor and a significant portion of the total mass of the trailer is borne by the tractor.

　　With the implementation of weight based toll collection on highways, light body suspension is becoming increasingly popular, and many users are switching from heavy body suspension to light body suspension to create better efficiency. Generally speaking, a 13 meter light body trailer can weigh nearly 3 tons less than a heavy body trailer. So, how is the weight of a light body trailer reduced?

　　Where is the lightness of lightweight trailers? High strength steel is the protagonist

　　The main beam is made of high-strength steel

　　The main method for reducing weight of lightweight hanging beams is to use high-strength steel, mainly 700 high-strength steel. Under a certain strength, the thickness of the upper and lower wing plates is reduced

　　In terms of the height of the main beam, the lightweight hanging should not be less than 500mm. Some manufacturers reduce the height of the main beam to 450mm, 420mm, or even 400mm in pursuit of lightweight, which is not advisable. It is also not advisable to use beam drilling for lightweighting.

　　There are also lightweight suspension beams that use one-time forming beams to reduce weight, and the weight reduction is very significant. Taking the 13 meter warehouse trailer beam as an example, the lightweight suspension with one-time forming beams is generally around 5.5 tons, while the lightweight suspension with high-strength steel beams is around 6 tons. The one-time forming beam can reduce weight by nearly 1 ton

　　However, the load-bearing capacity of a single formed beam is smaller than that of a high-strength steel "I-beam", and the toughness of the single formed beam is not good, which requires higher road conditions. And it cannot be overloaded, especially not concentrated for carrying.

　　The crossbeam adopts a "W" - shaped through beam

　　The weight reduction of crossbeams is mainly achieved through structural design and the use of thinner high-strength steel for weight reduction. Light weight hangers generally use thinner high-strength steel cold-formed edge beams to reduce weight, while ordinary heavy weight hangers generally use channel steel and bottom grooves.

　　In terms of design, lightweight trailers generally use a "W" - shaped through beam structure. Although it can effectively reduce the weight of the trailer, there is still a certain gap in load-bearing capacity compared to ordinary channel steel.
