In China's transportation industry, trailer is a widely used vehicle. Trailer refers to a vehicle towed by a vehicle without power driving device, which is a combination of one vehicle (truck or tractor, forklift) and one or more trailers.

Trailer is an important vehicle type of highway transportation. It has the advantages of rapidity, mobility, flexibility and safety. It can easily realize section transportation. The trailer can form a complete means of transport only together with the tractor or other vehicles.

The common Trailer models are full trailer and semi-trailer, so how to distinguish these two vehicles? In fact, it only depends on the support mode of the vehicle.

Full trailer means a trailer that can be supported independently. As the name suggests, the load of the full trailer is completely borne by itself, which is only connected with the main vehicle by hook. The main vehicle does not need to bear the trailer load, but only provides power to realize the traction and steering of the full trailer.

A typical full trailer is generally composed of frame, pallet (upper loading), drawbar (frame) (with hanging ring), steering device, suspension, braking system, signal system, etc. it is mainly used for transportation in docks, factories, ports and other fields.

Semi trailer refers to the trailer that cannot be supported independently, that is, the load of the semi-trailer needs to be borne by the semi-trailer and the main vehicle together. The front half of the semi-trailer is mounted on the traction saddle above the rear section of the tractor, and the bridge behind the tractor bears part of the weight of the trailer.

Semi trailer is the most commonly used Trailer in domestic transportation, which can be divided into many types, such as flat plate type, gooseneck type, concave beam type and various special semi trailers. Because of its flexible application and large bearing capacity, it is especially suitable for long-distance and high-grade highway transportation, and has become the most important means of transportation in highway transportation vehicles.

In fact, in addition to the above two categories, there is another Trailer model - center axle trailer. The structure of center axle trailer is between full trailer and semi-trailer. Its main weight is borne by the trailer, the main vehicle bears a small part of the weight of the trailer, and the traction and steering are completed by the main vehicle. Generally, the center axle trailer is suitable for operation on high-grade highways.

Although semi-trailer, full trailer and center axle trailer have different structures, they have their own advantages and disadvantages in different dimensions and play a role in their fields of expertise. However, no matter which Trailer model, if you want to improve the logistics transportation efficiency, reduce the logistics cost and ensure the safe operation, you must choose a vehicle axle with qualified quality and reliable performance.

As a leader in the domestic axle industry, Shandong Darong group has more than 20 years of deep cultivation experience in the industry. It has everything, such as German axle, American axle, concave axle, disc axle and special axle. After many years of market tests at home and abroad, it has always been in an invincible position.
