When buying a cargo trailer, it is difficult for many friends to decide which brand of stake trailer to buy. Do they want to buy a van trailer, fence trailer or side wall trailer? Below we will introduce different types of cargo trailers, a simple analysis, hoping to help more friends.
What is the difference between the different cargo trailer?
1. The advantage of the side wall semi trailer is that it is easy to load and unload, can transport large items, and can load large items easily. Railing semi-trailers are mostly used for transportation of furniture and building materials.
At present, the railing semi-trailer is mainly used for building materials transportation, furniture transportation and light cargo transportation. Some users have added a movable barn on the basis of the bar, and used the barnage as a barn.
As for the sidewall trailer in the existing freight market, they are generally mainly used for transporting building materials, furniture and some lightly thrown goods. It can be used as a dropside trailer.

2. The van semi-trailer. For this type of car, the first feeling for the card friends is worry, waterproof and anti-theft, and the trouble of covering the tarpaulin is also reduced.
In terms of loading and unloading, the current van light truck generally opens a side door, and the loading and unloading speed is not slow.
In addition, with the development of the city, many cities prohibit trucks from entering the city’s backbone areas and central areas with better economic development. Therefore, many van light trucks have complied with this policy and solved the restrictions on truck bans. The rapid development of express delivery has also led to a linear growth in the number of van light truck markets.
In order to ensure the safety of goods, some cargo owners will specifically specify the use of vans when looking for cargo trailer. Therefore, in large cities with more developed logistics, everyone can see the prevalence of van light trucks. At present, vans trailer has begun to occupy the mainstream position in the light truck market.
3.Compared with the van semi-trailer, the loading capacity of the warehouse semi-trailer is larger, the scope of the cargo semi trailer is wider than the van, and the loading and unloading is more convenient than the van.
There are two advantages of pulling the green pass in the warehouse rail. The first is to facilitate the inspection of the toll station. Everyone knows that Green Pass can avoid tolls when running at high speeds, so all toll stations are stricter in checking Green Pass. Warehouse truck semi-trailers are more convenient for inspection than van semi-trailers, reducing the hassle of moving goods up and down. The second advantage is that the warehouse semi-trailer has good air permeability. If you choose to use the ordinary van semi-trailer to pull the green pass, the temperature in the cabin is very high in summer, it is easy to stuff the fruits and vegetables, and the supply is wider than the van.
At present, the most common barn car in daily life is the car that pulls vegetables.
Fence semi trailer
Of course, there are many commonalities. The following is the details of the warehouse rail semi-trailer and the rail semi-trailer, which may help you.
1. Drop side semi trailer frame:
The frame is a space frame type low alloy steel welded structure. The frame is welded by two T-shaped longitudinal beams and beams to support the load. There are a traction pin and a traction pin plate connected to the tractor under the front of the frame. The front cross beam of the frame is provided with an air brake connector and a wire connection socket. The front and side of the frame are equipped with lighting or signaling devices.
2. Supporting device:
In order to make the semi-trailer reliably parked after leaving the truck head, the front end of the frame is equipped with two support legs that are linked left and right or left and right. It consists of a screw rod transmission mechanism, a bevel gear transmission mechanism, a two-speed reduction box, a transmission rod, an operating handle, and the like. When the handle is pushed in, you can get high speed lifting, and when the handle is pulled out, you can get low speed. When the base is in contact with the ground, it can only be lifted in low gear.
3. Axles and wheels:
Three axle assemblies of the same structure are installed under the suspension system. The axle is a square tube axle. The axle body is provided with a platform for mounting a leaf spring suspension and a bracket for installing a brake air chamber. The axle head is used to install wheels, hubs and brakes.
4. Suspension system:
Suspension device support is welded on the back and lower part of the longitudinal beam, and support device support is provided on the lower front part. The suspension system is a three-axis leaf spring suspension suspension, which is used to support the load and has the function of absorbing driving vibration and so on. The leaf spring suspension system is fastened to the axle body with U-bolts.
5. Traction pin:
The traction pin is an important component that connects the semi-trailer to the tractor and withstands traction, and is connected to the traction seat. It is generally forged from chrome-alloyed steel.
For different cargo tonnage, there are 50 # traction pin and 90 # traction pin. Generally, the limit is 50T trailer and the total weight of the cargo. Below 50T use 50 # pin, above 50T is 90 #, if above 90T, you will use 90 # traction pin.
6. Sidewall:
The side wall is divided into a flat plate and a vertical corrugated board. The vertical corrugated board is a typical board, and the strength will be higher. Can be detached or welded to death.
7. Protection device:
Trailer protection device consists of side protection and rear protection to protect pedestrians and other vehicles from getting under the semi-trailer. It can also reduce wind resistance and save fuel.
8.Electrical system:
The drop side semi trailer is equipped with an international electrical system that is compatible with the tractor. There are electrical connector sockets on the front beam of the frame. The rear of the frame is equipped with brake lights, turn signals, parking lights, reversing lights, license plate lights, fog lights and triangular reflectors, and front and side lights with front position and width lights, side marker lights, front right Equipped with ABS indicator. The voltage of various lamps is DC 24V.
9. Brake and operating device:
The drop side semi trailer uses a dual-line pneumatic braking system and is equipped with an anti-lock braking system (ABS).
