Abstract
A 'bogie' is disposed to be slid within a pair of tracks on a trailer. A movable pin element is adapted to pass through openings in at least one of the rails and tracks to secure the bogie to the trailer. The pin element includes means for providing a chamber to permit air pressure to release the parking brakes for the wheels of the bogie only when the pin is in a position securing the bogie to the trailer. If the pin is not in position, the parking brakes in the bogie cannot be released.
