With the popularization and implementation of high-speed weighing and charging throughout the country, and strict control of excess, light-weight hanging is becoming more and more popular. Many users have replaced their original heavy-weight hanging with light-weight and high-strength steel semi-hanging to create better benefits. Generally speaking, a 13-meter light-weight railing trailer can be nearly 3 tons lighter than a body weight trailer, so how does a light-weight Trailer lose weight?

Main girders are of high strength steel.

The weight reduction of light-weight hanging beam is mainly made of high strength steel, mainly T700 high strength steel. On the premise of guaranteeing certain strength, the thickness of upper wing and lower wing is reduced.

On the height of beam, light hanging is best not less than 500mm. Some manufacturers will reduce the height of beams to 450mm, 420mm or even 400mm in pursuit of lightweight. It is also undesirable to use beams to lighten holes.

Light-weight hanging girder is also used to reduce the weight of one-time forming beams, and weight reduction is very obvious. Take the 13-meter barn Trailer girder as an example, the light-weight hanging of one-time forming girder is generally about 5.5 tons, while the light-weight hanging of high-strength steel girder is about 6.5 tons. One-time forming girder can be light about 1 ton.

However, the bearing capacity of the girder is smaller than that of the high strength steel "I" beam, and the toughness of the girder is not good, which requires a higher road condition. And can not overload, especially not concentrated load.

The cross beam adopts "W" type through beam.

The weight loss of beams is mainly due to weight loss in structural design and the use of thinner high-strength steel. Lightweight hanging generally uses thinner high strength steel cold bending side beam to reduce weight, ordinary heavy hanging generally uses channel steel and bottom groove.

In design, the "W" type through beam structure is generally used for light-weight trailers. Although the weight of trailers can be effectively reduced, there is still a certain gap in the bearing capacity between the light-weight trailers and ordinary channel steel.

The bottom plate is made of thinner high-strength steel.

The bottom plate is thinner and high-strength steel. Light-weight trailers generally use 1.5mm, or even 1.25mm high and light steel as the base plate, while ordinary trailers generally use 3mm ordinary steel floor.

4 spring leaf springs are used for leaf springs.

For leaf springs, four lightweight leaf springs with thickening are used for light body suspension, while 10 leaf springs are generally used for ordinary heavy body suspension, which can reduce the weight of about half of the leaf springs.

To reduce the number of steel plates, etc.

Lightweight hanging is mainly achieved by reducing the thickness of steel on the carriage board and on the side beams of the upper side beams of the carriage. For example, on the side beam of the carriage, the channel steel is usually hung with 16# national standard steel, and the 14 channel steel or bending parts are replaced by the light body. Light weight high strength steel semi suspension, single tire air suspension, container skeleton, box trailer.
