The English name is Semi Trailer; the trailer itself does not have the ability to drive; the trailer needs to rely on external traction to operate. They will use the fifth wheel to connect to the tractor head and rely on the tractor to provide the power. Semi-trailer design is more flexible and can be applied to a variety of cargo transportation needs.
Semi-trailers are a significant part of the modern cargo transportation sector. The trailers can be customised according to the type and characteristics. Different trailers can provide optional road transportation solutions by transporting various cargo.
First of all. The semi-trailer needs to be connected to the tractor. They will use a fifth wheel and kingpin to connect with each other. The general fifth wheel and the kingpin have two different models: 2” and 3.5″ two models to match various semi-trailers with the tractor.
Semi-trailers can be divided into two categories according to demand: ordinary semi-trailer type and particular semi-trailer type: Ordinary semi-trailers include fence cargo, container transportation and van-type semi-trailers
Particular semi-trailers include low bed, dump tipper, liquid transportation, powder bulk transportation, special semi-trailers and full trailer
Introduction of semi-trailer categories
CATALOGUE NAME USES CHARACTERISTIC
Ordinary Semi-trailer Fence Cargo Trailer Application for bulk cargo transportation for long distances The frame is of through-beam type, and the longitudinal beams are of a one-piece structure welded by automatic submerged welding.
Container Transportation Trailer Application for transportation for ships, port terminals, etc. Specialized in a variety of container transport; can be used directly in the container transfer of goods, to achieve rapid loading and unloading more convenient and rapid
Van-type semi-trailer Application for the transportation of break-bulk goods The van-type semi-trailer adopts a closed-side protection design, which can reduce the lateral risk when the vehicle is travelling at high speed and reduce energy consumption.
Special Semi-trailer Low Bed Trailer Application for the transportation of a wide range of machinery and equipment, large objects or steel. The low cargo surface of the frame ensures the smoothness of transportation; at the same time, the load surface of the frame can be designed according to the customer’s requirements, which can satisfy the transportation of all kinds of special goods.
Dump Tipper Trailer Application for transportation of coal, gravel, construction materials, etc. The carriages adopt side and rear tipping methods, effectively improving unloading and transportation efficiency.
Liquid Transportation Trailer Application for transportation of all the liquid Different materials can be used depending on the medium to be transported, such as carbon steel, stainless steel or aluminium alloy.
Powder Bulk Transportation Application for transportation of all kinds of powder materials products Different materials can be used depending on the medium to be transported, such as carbon steel, stainless steel or aluminium alloy.
Special Trailer Application for transportation of special equipment Semi-trailers specially designed for special equipment
Full Trailer Mainly application for on-site transportation in terminals, factories, ports, etc. Increased efficiency of cargo transit panning. Reduced cost of forklift and labor consumption
The main components of the different semi-trailer types are roughly the same. They consist mainly of the frame, suspension, support system, and braking and circuit systems.
The frame of the semi-trailer is used to support the load. It is installed with the traction pin, suspension and other major components. It is the main bearing part of the vehicle. The frame mainly consists of longitudinal beams, cross beams and other elements of the space frame structure. Generally, the whole piece will use high-strength steel, such as T700, etc… which gives the whole frame part a strong load-bearing capacity and will not be easily deformed.
The braking system is a device used to control the braking of the semi-trailer when travelling on a normal road, emergency self-braking, etc.
When the semi-trailer does not connect to the tractor, the support device is used to support the front load of the semi-trailer. The support device is also called landing gear. There are two types: gear inside and gear outside, control from one side and control from both sides.
