The difference between drawbar flatbed trailer and a platform semi-trailer

June 3, 2020

Many people will ask what is the difference between a drawbar flatbed trailer and a platform semi-trailer. In fact, a full trailer and a semi-trailer are only connected differently than the traction car in front. Below we will introduce the difference between a semi-trailer and a full trailer.

Platform full trailer

Flatbed drawbar trailer is the front end of the trailer connected to the rear end of the tractor. The tractor only provides a pulling force and does not bear weight. That is, a full trailer is added behind the ordinary car, and the two are connected by a hook. The trailer can increase the loading capacity of the truck and reduce fuel consumption, thereby reducing transportation costs.

The load of the trailer is fully borne by itself, and it is only connected to the locomotive with a hook. The locomotive only provides power to help the trailer overcome the frictional resistance of the road. A trailer can stand upright on its own tires, while a semi-trailer must stand on its front legs.

Different models of semi-trailer

There are many types of semi-trailers, such as flatbed semi-trailer, side wall trailer, fence cargo trailer, fuel tanker trailer, bulk cement tanker trailer, container skeletal trailer, van semi-trailers and special semi-trailers, etc.

The use of semi-trailers is very wide. Compared with other ordinary trailers, semi-trailers can bring more economic income. With the strong carrying capacity and large loading capacity of semi-trailers, one truck can load three times the goods of ordinary trucks. This shows that the semi-trailer brings more benefits to customers.

With respect to the car body, the tow bar or tow frame of the trailer can swing up and down or left and right. It is also used in mountainous areas or on bad roads.

Flatbed semi trailer:

A full trailer or a flatbed semi-trailer is also the same without its own power device. The flatbed semi-trailer is a type of trailer whose axle is located behind the center of gravity of the vehicle.

The trailer is equipped with a coupling device that can transmit horizontal or vertical forces to the tractor.

Part of the total weight of the trailer is borne by the tractor. It doesn't have itself power, it is carried together with the truck head, and the container carrier semi-trailer is driven by the tractor.

Flatbed trailer is usually used to transport 20ft or 40ft containers.

They are mainly used for container transportation supporting ships, ports, shipping lanes, highways, transit stations, bridges, tunnels, and multimodal transport.

Use platform trailers to transfer cargo at the shipper’s warehouse. Unloaded to the consignee’s warehouse, when changing trailer or boat on the way, there is no need to take the goods out of the box and change them.
