Abstract
A reversible connector and method of connection between a large road making machine and the fifth wheel of a tractor to facilitate towing of the machine. The connector has a downwardly projecting king pin which is adjustable between a retracted, operating position and an extended, towing position. It can be either slid or pivoted between those positions. The connector can be used on an apparatus having a chassis, a downwardly extending conveyor pivotally attached to an end of the chassis and a hydraulic cylinder to pivot the conveyor relative to the chassis. The hydraulic cylinder can lift the inlet end of the conveyor off the ground to put the fifth wheel connector in a position such that it can engage the fifth wheel of a tractor. The hydraulic cylinder also can be used to pull the front portion of the chasis up off the ground.
