When it comes to trailers, the first thing that comes to mind is the crates in the transport vehicles. Tanker trailers, which are used for transportation with the help of vehicles such as trucks or tractors, are freight transport vehicles, which we can call semi-trailer, and are towed with at least one axle and tractor. Tanker trailers can carry a large part of the load thanks to the axle on which it is attached. A king pin adapter is used to connect the towing vehicle and tanker trailers, which allows two machines to be connected without any problems. There are special sections in the tractor for connecting the king pin to the trailer. Anker trailers have the ability to carry all kinds of heavy loads. They are among the most used vehicles in transportation operations. In addition to Flat, Jumbo, Normal Open and Lowbed trailer types, tanker trailers carrying various materials also play an important role in the logistics sector.
