With the rapid development of China's economy and the strong investment of the country in
highway construction, highway transportation has become the main mode of transportation in
China. As the main equipment for highway transportation, semi trailer tractors are widely used
due to their advantages of strong specialization, large loading capacity, and fast transportation.
The traction seat is the connecting device between the tractor head and the semi-trailer. Although
it is not a very complex and eye-catching component, it is the most important safety equipment
for a semi-trailer tractor.

According to whether the support can move, it is divided into fixed type, mobile type, and lifting type.
The left and right supports of the fixed traction seat are fastened to the traction seat base by bolts, and
the base of the traction seat is then fixed to the main beam of the tractor. Fixed type is the most widely
used type. There are many styles of mobile traction seats, and their structure is almost the same as that
of fixed traction seats. The main reason is that the connection between the traction seat base and the
tractor beam adopts a porous or toothed design. The base of the traction seat can be moved back and
forth according to the needs of connecting the trailer, so as to smoothly connect with different trailers.
Some mobile traction seats are also equipped with automatic air pressure control devices, which can
push the traction seat forward and backward in the chute through air pressure. The lifting type traction
seat is mainly used on towing vehicles at ports and docks. The traction seat can move up and down within
a certain range to adapt to semi trailers of different heights.
