A kingpin, or fifth wheel, is an essential part of the semi truck system. It is a large metal pin that attaches the trailer to the truck.
It is located directly under the trailer’s cab and locks it in place when connected to the truck’s frame. The kingpin allows for easy maneuvering and turning of the trailer as it follows the movements of the truck.
The kingpin consists of two main parts: an outer locking sleeve and an inner pin. The outer sleeve slides over the inner pin and locks into place.
This ensures that the kingpin remains secure while in operation. The inner pin is also designed to rotate, allowing it to easily turn with the trailer as it follows behind the truck.
There are several different types of kingpins available on semi trucks today. Most are adjustable height models that allow for easy installation and removal from a variety of different height trailers. The most common type is a heavy-duty model which offers greater strength than its lighter counterparts.
When choosing a kingpin for your semi truck, it is important to consider factors such as weight capacity, ease of installation and maintenance, and durability. A good quality kingpin will provide reliable performance for years to come.
