Interlink trailer,also know as superlink trailer. Simply put, the interlink trailer is composed of two flatbed trailers, the front one is a 20FT flatbed trailer, and the rear one is a 40FT flatbed trailer. After the assembly is completed, only need one tractor truck can be used to drive the two flatbed trailers. So you can think of it as a combination of two flatbed trailers of different sizes.

According to different trailer body, the interlink trailer can be divided into three types:interlink trailer with side walls, interlink trailer without side walls and interlink trailer with poles, which are suitable for different transport situations. 

Like other flatbed trailers, the interlink trailers are also equipped with container locks, so their common characteristic is that they can transport containers. There are 4 container locks on the 20FT flatbed trailer, which can transport a 20FT container;There are 12 container locks on the 40FT flatbed trailer, which can transport one 40FT container, or two 20FT containers at the same time,or when necessary, only transport a 20FT container in the middle of the flatbed trailer to prevent uneven weight distribution and threaten driving safety.

How to link the trailer?

First of all, we need to install a special trailer hook on our tractor. The trailer hook is generally divided into universal type and ready-to-use type.
Universal towing hook:
The tow hook generally does not need to replace the vehicle after the anti-collision beam, if you install the original anti-collision beam in the bearing body of the vehicle, you need to strengthen the beam, and then weld the tow hook on the anti-collision beam. Bearing type body of the vehicle,collision beam at the back is relatively thin, its role is only used to cushion the impact of vehicle collision, reduce vehicle loss, but can not meet the work of towing hook towing large weight trailer.
Ready-to-use drag hook:
This type of towing hook can only be used for some parallel imported truck with trailer sides. As we often mentioned, F-150 Raptor is equipped with the reserved interface of towing hook integrated with rear collision beam. This ready-to-use towing hook can be removed at any time when not in use, which is very convenient.

After the tractor coupler is installed, the trailer can be connected. The main connection modes of the trailer are the trailer coupling arm and the fifth wheel trailer.
Drag and drop link arm:
The tow hook is the most common connector on a trailer, having either with wheels or a jack that needs to be lifted, in the same way by connecting the hook ball at the end of the head tractor to the tow hook arm.
Fifth wheel trailer:
However, there is also a special towing structure on the truck, also known as the "fifth wheel" trailer, which makes it the first choice for heavy-duty pickup trucks. The upper right corner is attached to the carriage of the tractor by a tow-link mounted in the carriage. This unique design is more suitable for trailer.

Many people are worried about whether the trailer will brake after connecting the trailer. Are there any safety concerns? Because most European-style trailers use impact brakes, there is no need to connect brake lines.
These are now available in some Chinese trucks, but more vehicles do not have them and require additional wiring. General use the rear light wiring scheme, this scheme needs to pay attention to the original trailer wire bearing capacity and construction safety.

The main market of interlink trailers is Zambia, Botswana, Zimbabwe etc. Due to local policies, there are strict requirements for the load of the trailer. So in order to transport more goods per trip,ordinary trailers have become unsuitable to meet the needs of transportation companies,the emergence of the interlink trailer perfectly solved this problem. Using the interlink trailers, the efficiency of each trip can be increased by more than 50% to obtain more profits.
