1. Skeleton type.
Skeleton transport vehicles are composed of column structures on both sides, without side door panels, front panels, rear panels or top panels, and the vehicles being transported are directly exposed on the outside.
The cost of this type of vehicle is relatively small, it is more advantageous in terms of weight and consumes less fuel. However, the transported vehicles are easily damaged and the protection of the goods is poor.
2. Fully enclosed.
A fully enclosed transport vehicle means that the side panels and front panel are all closed with door panels, the top panel is of tent pole tarpaulin type, and the rear panel is designed with a rear door, similar to a van type.
This type of vehicle is just the opposite of the skeleton type. It is heavy in weight, consumes a lot of fuel, and costs a lot, but it has strong protection for the goods, that is, the vehicle being transported. It is generally used to transport expensive vehicles, and it can also be used to transport other goods.
3. Semi-enclosed type.
The semi-enclosed transport truck is between the skeleton type and the fully enclosed type. It is equipped with door panels on both sides and cancels the top sheet and rear door. Its advantages and disadvantages are also between the former two models.
In the past, the supervision of vehicle transportation by relevant departments was relatively small. Therefore, driven by interests, some people began to play tricks on the carriages, such as lengthening the vehicle by modifying the push-pull tail structure, or widening the upper pallet to separate the single-row carriages. Change to double row for higher transport capacity.
There are also different names in the industry for models with different transportation volumes. For example, "single row", "single cage" and "small cage" refer to transport trucks with single rows on both upper and lower floors, which can generally hold 12-13 vehicles; "two monsters" and "T cage" refer to the upper floor. It is a transport truck with double rows and a single row on the lower floor. It can carry up to 18 vehicles. If the lower floor can be hydraulically lifted to stack the vehicles, it is called "airplane jumping". It can generally hold 20-24 vehicles; the "big monster" refers to There are double-row transport trucks at the top and bottom, which can generally transport more than 30 vehicles.
After the introduction of the new GB1589 regulations, the relevant departments have greatly strengthened their supervision of the vehicle transportation industry. In addition to bans and fines, they have also added penalties from the corporate credit system. If there are violations, whether it is a passenger car manufacturer, a carrier, Drivers will be included in the list of dishonest parties involved in serious violations of laws, overloading, and overloading.
At present, in the vehicle transportation industry, flat-head tractors + trailers, long-head tractors + trailers, and center-axle vehicle transporters are gradually showing a tripartite trend. Under regulatory standards, flat-head tractors + trailers can carry 6 vehicles, and long-head tractors + trailers can carry 6 vehicles. The head tractor + trailer can carry 7 vehicles, and the center-axle trailer can carry 8 vehicles.
In view of the particularity of the goods transported by vehicle transportation semi-trailers, generally the requirements for vehicle stability, vehicle center of gravity, and vehicle self-weight are higher. Choosing the right axle and suspension will get twice the result with half the effort.
