Product Description

The function of king pin is to engage the semi-trailer to the fifth wheel. The king pin is the most critical component used in the load tranfer from semi-trailer.

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 horseshoe-shaped coupling device called a fifth wheel on 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.

Kingpin adaptor to couple a 2" kingpin on a 3½" fifth wheel

• Ideal for shunting of different semi-trailer tractors

• The D-value of the 2" kingpin remains unchanged

• Important:

The adaptor is suitable for temporary use on private sites only, e.g. on non public park grounds or for short tow runs.
