ABSTRACT:
A simpler, more direct mechanism for locking and unlocking of a king pin of a fifth wheel is provided. The mechanism includes a jaw member, a wedge member, a bumper member and a lever member interconnecting the jaw member, the wedge and the bumper member. The system may be operated by a two-way air cylinder, a one-way air cylinder or in an alternate embodiment, may be incorporated into an existing manually operated fifth wheel system as a retrofit assembly so as to convert existing fifth wheel locking mechanisms to the arrangement of the present invention.
