ABSTRACT:
A power actuating mechanism uses a mechanical spring to normally urge a pin through openings in a track and rail of a trailer and bogie, respectively, to lock the trailer to the bogie. Structure is provided to selectively apply air pressure to an actuator to overcome the bias of the mechanical spring and move the pin out of the opening in the track of the trailer to unlock the bogie from the trailer for repositioning or removal.
