Abstract
Disclosed herein is a fifth wheel hitch having a set of jaws removably retained in a pocket on the underside of the bearing plate, replaceable by like jaws or jaws accommodating a different size kingpin. The hitch can be of forged aluminum, for on-highway or off-highway usage. A swinging jaw is pivotally connected to a fixed jaw, and has a lower closure finger contacted by the head of a properly elevated kingpin to close the jaws. The jaws are locked closed by a locking plunger actuated with full jaw closure, by means of a trigger release mechanism. The trigger and plunger are retracted by a slide cam having actuators extending from both sides of the hitch. Adjustment of the jaws for wear is from the hitch exterior, and effectual whether the hitch is coupled or uncoupled.
