Abstract
Jaws of a fifth wheel hitch have front arms that overlap each other. The jaws are linked for simultaneous movement at the same speed and corresponding positions when closing around the kingpin, and a pawl holds the jaws closed. A handle moves a pawl to unlock the hitch to allow ejection of the kingpin, and once the jaws are open the pawl holds them open. A position indicator is linked both to the handle and to one of the jaws. The position indicator moves between three indications: locked, unlocked and open.
