Abstract
A collapsible, self-propelled stanchion having a pair of struts pivotally connected at a king pin mating element and wheels at their other end. A motive and propulsion system interconnects the wheeled ends to raise and lower the stanchion as well as propelling the stanchion along the deck of the railroad car using an internal or external source of rotation.
Claims15
A stanchion for a trailer to be transported on a railroad car comprising:
- mating means for mating with a king pin of a trailer;
- first and second strut means pivotally connected to said mating means at a first end and surface engaging means mounted on a second;
- motive means interconnecting said second ends of said first and second strut means for moving said second end of said second strut means relative to said second end of said first strut means to raise and lower said mating means;
- and
- propulsion means connected to said engaging means on said first strut means for driving said engaging means on said first strut means to move said stanchion along a surface of a railroad car when activated and for maintaining said second end of said first strut means stationary when deactivated.
