ABSTRACT:
A removable locking mechanism for a fifth wheel hitch is provided which includes a mounting plate removably attachable within a fifth wheel chassis formed to support a fifth wheel hitch plate that has an aperture in the load surface thereof. The mounting plate is formed with a u-shaped throat dimensioned to receive a trailer kingpin and a top surface configured to be co-planar with the fifth wheel hitch plate load surface when seated within the chassis. A locking mechanism for retaining the kingpin against said closed end of the throat is mounted to the underside of the mounting plate and includes a cam arm; and a bumper arm pivotally attached to the cam arm configured to engage a bumper stop formed in the mounting plate underside; a sliding jaw member slidably mounted to the cam arm; and a secondary lock member for preventing unintended disengagement of the lock mechanism.
