The fifth-wheel coupling provides the link between a semi-trailer and the towing truck, tractor unit, leading trailer or dolly. Some camper trailers use a fifth-wheel configuration, requiring the coupling to be installed in the bed of a pickup truck as a towing vehicle, and "fifth wheel" is therefore sometimes used as a synonym for such campers in North America. The coupling consists of a kingpin, a 2-or-3 ¹⁄₂-inch-diameter (50.8 or 88.9 mm) vertical steel pin protruding from the bottom of the front of the semi-trailer, and a horsesshoe-shaped coupling device called a fifth wheelon the rear of the towing vehicle.

As the connected truck turns, the downward-facing surface of the semi-trailer (with the kingpin at the center) rotates against the upward-facing surface of the fixed fifth wheel, which does not rotate. To reduce friction, grease is applied to the surface of the fifth wheel. The configuration is sometimes called a turn-table in Australia and New Zealand, especially if it is a rotating ball-race-beraing type.

The advantage of this type of coupling is towing stability.

How Do I Use A Pintle Hook In Combination with a Fifth Wheel System?

Fifth wheel systems have been in use since the horse-and-cart carriage era. In fact, that’s why they are called “Fifth wheel systems”,: they would have been considered a fifth wheel on a four wheel carriage – which would have connected a trailer to the vehicle that the horses could pull.

A fifth wheel system is a ball and socket join that is attached to the back of your vehicle. To use it with a pintle hook, you simply connect the pintle to the joint – think of the pintle hook as the connector of the fifth wheel system.

The system gives incredible security – heavy duty pintle hooks and fifth wheel systems are incredibly durable. They’re designed to be so strong that the vehicles would be damaged long before the connection.
