Introduction to Heavy Low Plate Semi trailer and Fender Semi trailer

Heavy low platform semi-trailer

The heavy low plate semi-trailer is used to load the trailer with super large and overweight cargo. The basic form of heavy trailer is single flat trailer. It generally has the following structure. The frame and axle axles are mostly collinear, that is, there are two left and right axles on one axis, also known as two axle trains. The common single flat trailer has 2-7 axes. One axle is equipped with four tires, and one axis has eight tires. Therefore, the width of the whole vehicle can be more than 3m. In order to reduce the center of gravity of the whole vehicle, steel wire radial wide rim tires with small diameter and large load capacity (see automobile tires) are generally used. Each tire can withstand a load of about 4 tons under low speed operation conditions. The frame adopts the welded structure of high-strength alloy steel box section. Generally, a single flat trailer with five axles and two axle trains can carry more than 100 tons.

Fence type semi-trailer

Fence type semi-trailer A semi-trailer whose loading part is a fender structure. It is widely used, mainly for medium and long distance transportation of medium and heavy goods and bulk goods. With strong applicability, it has become the first choice of medium and long distance freight vehicles.

1. The vehicle body is made of high-quality steel, advanced technology and strict production. The vehicle has reasonable structure, reliable performance, simple operation and beautiful appearance.

2. The frames of series semi trailers are of beam through structure, and the longitudinal beams are of straight type or gooseneck type. The web is welded with manganese plates from 400mm to 550mm in height. The longitudinal beam is automatically submerged welded. The frame is shot peened. The cross beam is penetrated into the longitudinal beam and welded as a whole.

3. The suspension is a rigid suspension of non independent steel plate punching type, made of tandem steel plate springs and suspension bearings; The structure is reasonable, with strong rigidity and strength, which is used to support the load and mitigate the impact.
