Truck Fifth Wheel Plate Assembly JSK37DV1 JSK37DV2 JSK37DV3 with Jost Fifth Wheel Repair Kit Accessories
Product Description
A fifth wheel is a hitch attachment that you can add on to the bed of the truck, tractor or similar vehicles. You connect cargo to the U-shaped hitch which then evenly distributes the weight over the truck or tractor. The device rests on hinges, which makes it much more flexible when driving around.
The fifth-wheel coupling provides the link between a semi-trailer and the towing truck, tractor unit, leading trailer or dolly. 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. 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-bearing type. The advantage of this type of coupling is towing stability.
