Vehicle transport semi-trailer, as the name suggests, is a semi-trailer specially used for transporting vehicles, such as passenger cars such as transport cars, vans, commercial vehicles and jeeps. It generally has the characteristics of stable lifting, light structure, safe and convenient operation and good driving smoothness.

The rise of vehicle transportation logistics industry can be traced back to the early 1990s. Users' requirements for the quality of passenger cars have improved. The original way of driving new cars directly from the manufacturer to the dealership through the manufacturer's special driver can not meet the needs of users, because that means that the new cars bought by users have driven a long way. So the concept of "zero kilometer transportation" appeared, and the new car was transported to the dealership by special transportation vehicles.

So, how many types of vehicle transportation semi-trailer can be divided into?

1. Skeleton type.

Skeleton transport vehicle, that is, both sides are composed of column structure, without side door panel, front panel, rear panel or top panel, and the transported vehicle is directly exposed to the outside.

The cost of this model is relatively small, the weight is relatively dominant, and the fuel consumption is less. However, the transportation vehicles are easy to be damaged and the degree of protection of goods is poor.

2. Totally enclosed.

The fully enclosed transport vehicle, i.e. the side panel and the front panel are closed with door panels, the top panel adopts canopy pole tarpaulin type, and the rear panel is designed with rear door, which is similar to van type.

On the contrary to the skeleton type, this model has the advantages of heavy self weight, high fuel consumption and high cost, but it has strong protection for goods, that is, the vehicles transported. It is generally used for the transportation of expensive models, and can also be used for the transportation of other goods.

3. Semi enclosed.

The semi enclosed transport vehicle is between the skeleton type and the fully enclosed type. It is equipped with door panels on both sides and cancels the top plate and rear door. Its advantages and disadvantages are also between the first two models.

In the past, the supervision of relevant departments on vehicle transportation was relatively small. Therefore, driven by interests, some people began to do tricks on the carriage, such as lengthening the model by modifying the push-pull tail structure, or widening the upper supporting plate to change the single row to double row, so as to have a higher transportation volume.

For models with different transportation volume, there are also different names in the industry. For example, "single row", "single cage" and "small cage" refer to the transport vehicles with single row on the upper and lower floors, which can generally hold 12-13 vehicles; "Er Guai" and "t cage" refer to that the upper layer is a double row and the lower layer is a single row of transport vehicles, which can carry up to 18 vehicles. If the lower layer can be lifted hydraulically to stack the vehicles, it is called "aircraft jump", which can generally hold 20-24 vehicles; "Big monster" refers to double row transport vehicles up and down, which can generally transport more than 30 vehicles.

After the introduction of the new gb1589 regulations, the relevant departments have greatly strengthened the supervision of the vehicle transportation industry. In addition to the ban and fines, they have also added the punishment of the enterprise credit system. If there are violations, whether it is the passenger car manufacturer, the carrier and the driver, they will be included in the list of serious violations, overloading and dishonest parties.

At present, in the vehicle transportation industry, flat tractor + trailer, long tractor + trailer and center axle vehicle transport vehicle gradually show a tripartite trend. Under the laws and standards, flat tractor + trailer can carry 6 vehicles, long tractor + trailer can carry 7 vehicles and center axle trailer can carry 8 vehicles.

In view of the particularity of the goods transported by the vehicle transport semi-trailer, the requirements for vehicle stability, vehicle center of gravity and vehicle weight are generally higher, and the axle and suspension are selected to get twice the result with half the effort. Darong group is one of the earliest enterprises in China to start mass production of integrated axles. It has been deeply engaged in the axle industry for 20 years, and its technology, technology, experience and strength are at the forefront of the industry. Its disc axle, drum axle, low flat axle, concave axle, three-line six axle axle axle, air suspension, single point suspension and other products are rich and diverse, which can meet the diversified use needs of users.

The special size can provide customized services, adhere to the cost-effective route in terms of price, and the sales network covers the whole country. It has established stable and good cooperative relations with many Trailer enterprises, logistics companies, transportation fleets and retail owners.
