Fifth wheel helper |
摘要 |
A fifth wheel helper is adapted to be inserted underneath a fifth wheel hitch plate to hold it in a horizontal position so that the truck can be pulled forward after the king pin of the trailer has been trapped behind the fifth wheel. The fifth wheel helper comprises a solid piece of material having a tapered first end and a flat second end and an indentation on an underside thereof for engaging a truck frame rail to hold the fifth wheel helper underneath the hitch plate. A safety bolt is provided for locking the fifth wheel helper on the truck frame rail.
