ABSTRACT:
A fifth wheel hitch includes a head assembly having a skid plate with an opening for receiving a king pin of a trailer and a locking jaw assembly for securing the king pin in proper position with the trailer over the skid plate. Additionally, the fifth wheel hitch includes a rocking platform having an arcuate rocking surface and upstanding wings at each end thereof. A pair of pivot pins are provided for mounting the head assembly to the wings of the rocking platform while allowing pivotal/tilting movement of the head assembly in a fore-and-aft direction relative to the rocking platform. A base is provided including a cradle for receiving the rocking platform. The cradle allows side-to-side rocking movement of the rocking platform and the head assembly relative to the base. The base includes first and second pairs of opposed mounting lugs. A pair of mounting pins are received in the first and second pairs of mounting lugs and serve to capture the rocking platform on the cradle of the base.
