Link Manufacturing says its Easy Slider Sliding Kingpin system allows drivers to adjust the trailer kingpin position within 8-in. increments on a fully loaded, connected trailer without having to disconnect the kingpin from the fifth wheel.

By varying the overall length of the tractor/trailer unit, Link says, the axle weight distribution can be optimized for particular load configurations and road conditions, thereby maximizing payloads and improving traction. Minimizing the distance between the tractor and trailer also allows for a tighter turn radius within constricted maneuvering situations. Easy Slider can be coupled with any tractor or trailer, Link adds.

Easy Slider eliminates the limitations of a sliding fifth wheel, the inflexibility of a fixed kingpin setup and the high maintenance of a sliding upper plate system, the company says, adding that the Easy Slider kingpin systems shifts the weight from the drive axles to the trailer axles and vice-versa.
