ABSTRACT:
A improved detachable fifth wheel hitch device with a pivotal locking ramp, which replaces a supplied fifth wheel hitch plate device attached to a truck or pickup mounted fifth wheel hitch base, provides an extended collar hitch plate above a kingpin receiver channel incorporating a pivotal locking ramp directing a kingpin into the kingpin receiver channel, over the pivotal locking ramp during loading, the pivotal locking ramp returning to an erect position, blocking removal of the kingpin once past the pivotal locking ramp unless the kingpin is raised vertically out of the kingpin receiver channel, thus preventing unintentional release of the kingpin from the kingpin receiver channel during loading, unloading or transport.
