Description
Description:
The trailer fifth wheel is the connection between the semi trailer and the tractor, tractor unit, lead trailer or trailer. The fifth wheel connects the two components, allowing them to move flexibly and steer comfortably. Without the fifth wheel, the semitrailer would be almost impossible to turn. The fifth wheel evenly distributes the weight between the tractor and trailer, allowing you to get on the road and maneuver your equipment with ease.
As a whole, the fifth wheel connection system consists of the fifth wheel and the kingpin. Among them, the fifth wheel is a flat, non-rotating horseshoe-shaped connection device installed at the rear end of the tractor.
The kingpin is a metal part protruding from the trailer, often referred to as the “pivot point between the tractor and the semitrailer.” The kingpin on the trailer is installed into the fifth wheel of the tractor. The surface of the semitrailer with the kingpin in the center rotates against the friction of the fifth wheel facing upward.
