The fifth wheel coupling is a critical component in the world of transportation, serving as the essential link between a semi-trailer and the towing truck, tractor unit, leading trailer, or dolly. This mechanical device is designed to provide a pivot point that allows the safe and efficient handling of heavy loads.

The term "fifth wheel" comes from the large circular plate, or "wheel," that engages with the trailer's kingpin to ensure a secure connection. This connection is crucial in maintaining the stability and control of the vehicle, especially when transporting heavy loads over long distances.

In the trucking industry, the fifth wheel coupling is a standard feature on most heavy-duty trucks. It's designed to handle the weight and stress of pulling a semi-trailer, which can weigh several tons. The fifth wheel coupling is a testament to the engineering prowess of the trucking industry, enabling the transportation of goods across vast distances with relative ease.
