How many types of semi-trailer do you know?

Trailer is a big key transport volume , and difficult to split bulky goods , such as excavators , etc., are more suitable fence to pull fresh class of goods , such as vegetables, fruits , etc. are more suitable van pull bulk and moisture more expensive goods

Dump/Tipper semi-trailer

Dump/Tipper semi-trailer suitable for the transport of coal, ore, building materials and other bulk goods scattered. Dump trailer use can be divided into two categories: one category is used in non- road transportation of heavy and super heavy dump trailer is mainly responsible for large-scale mining, engineering and other transport tasks, and generally supporting the use of excavators. Another part of the road transport of light, medium and type dump trailer is mainly responsible for ordinary sand, mud, coal and other bulk cargo transport, often with supporting the use of loaders. 

1. The use of rollover and rear compartments turn dump mode, which can effectively improve transport efficiency loaders transporting bulk goods scattered. 

2. The frame and carriage stringers are made of high quality manganese plate welded dustpan and rectangular cartons have two kinds. High strength, lifting ability, stiffness, toughness, strong carrying capacity, without permanent deformation. 

3. Sophisticated technology: the main components of advanced processing equipment, Stringer has made automatic submerged arc welding, using the precise assembly of axle assembly machines, steel spring.

Low flatbed semi-trailer for loading heavy oversized and overweight shipments trailer. The basic form of a monomer heavy trailers trailer plate. It generally has the following structure. The frame and the axle shaft of a two-axis multi -line, i.e., an axis in the two right and left axles, also known as two-axis column. Common monomers having from 2 to 7 trailer plate axis. An axle mounted four tires, an axis have eight tires. So the entire vehicle width of up to 3 meters. In order to reduce the vehicle center of gravity, generally equipped with small diameter steel radial load capacity of the tire rim width (see car tires ), each tire at low load operating conditions can withstand about four tons. Frame welded structure of high-strength alloy steel box section. Typically a 5 axis, two-axis single flat trailer can load more than 100 tons column.

Low flatbed semi-trailer

Stake semi-trailer laden parts of the structural design of the trailer using the fence. Mainly used to transport agricultural goods and other light bulbs.

1. Models and structural design technology combined with user- fence the goods category, designed to meet under load sufficiently to reduce car weight, simple structure suitable for easy removal for users to reduce investment costs and create more profit value. 

2. Frame: the use of stringers and beams throughout the whole group welded space frame structure. A balanced frame of strength, stiffness , toughness, strong bearing capacity, without permanent deformation.

3. Series Stake trailer frame are wearing beam structure, the use of straight- stringer or gooseneck. Web height from 400 to 500, automatic submerged arc welding stringers, frames using blasting treatment , beams and stringers penetration welding as a whole. 

4. Suspension system: the new suspension system, high strength, high impact resistance; each axle load balancing, the angle lever system designed, in operation during the frequent bumps, reducing the friction between the tires and the slippage distance, reduce tire wear, while adjustable rod, adjustable wheelbase, avoid bias tires round run- bite phenomenon .

Container trailer

Container semi -trailer laden parts of the container structure. Mainly used in ships, ports, route, highway, transit stations, bridges, tunnels, supporting intermodal logistics system. 

1. Designed to transport a variety of containers. Long-term repeated use, has sufficient strength. 

2. The use of container transhipment directly at the shipper's warehouse loading, unloading shipped to the consignee's warehouse, half replacement car, the boat, no need to dress up the goods removed from the box. 

3. Can be fast loading, and easy facelift directly from one means of transport to another means of transport. 

4. Easy to fill and unload goods to satisfy customers' individual needs. According to customer needs tooling to ensure stable quality and reliable performance. 

Container trailer is dedicated transport trailer carrying containers. The early development of container transport, container load due to small number of small, mostly ordinary truck carrying. Since the 1960s, with the rapid development of container transport, the countries have developed into a specialized container transport vehicles. Container trailers loaded parts of the size determined by standard container size, and a twist lock means holding the container in the bottom corners of the container corresponding to the position. Dedicated transport trailer carrying containers. In parts of the four corners of the loading device is fixed with a twist-lock containers. Usually semitrailer, all hanging and double hanging, with semitrailer as much. Another semitrailer flatbed and skeleton points, the former with a flat cargo units, can also be used to grow ordinary cargo shipment; latter without the dock, in the end plate mounted on the container frame, fixed by the twist-lock devices become semi-trailer strength member.

Ultra-light trailer by definition is better than many ordinary cars lighter car , in the end how much is ultra-light light it, the definition of an ordinary car industry is quite heavy, quite size, light weight at least 15% of the car is defined as the ultra-light. There are several semi-trailer light can be achieved in order to: 

1. reducing the plate thickness. This high- grade steel to the point . High standard steel, high strength, good toughness, fatigue 

2. Reduce the weight of the rear axle. Axles plus suspension is now close to two tons, only light bridge, disc brakes, four leaf springs, new lug, vacuum tire, tires, etc. are single effective approach 

3. Becomes suspension. Using airbag suspension can be, this is seldom 

4. Reduce the weight of subsidiary parts. Reduce weight bumpers, side protective nets, comb spare tire rack, toolbox, tarpaulin rack, etc. 

5. There is the use of suspended rear axle, which is the last bridge you know when not in use can improve now the most commonly used the approach is to use high strength ( domestic high-grade ) steel, to reduce weight. High-strength lightweight steel trailer trailer weight than ordinary carbon steel and lighter. The use of high strength steel imported from Sweden, to optimize the design of the trailer, the trailer carrying amount does not change the situation, to reduce trailer weight over 1.3 tons, can effectively improve the efficiency in the use of the vehicle.
