Abstract: The present suspension mechanism for load dividing gates of single column type promotes reliability and safety by extreme simplicity and unity of carriage structure, together with highly effective provision against structural failure even of the inherently rugged support elements. By means of features including special bearing design, roller placement and novel keeper support, the invention provides suspension of a column gate from a single track with security against structural failure believed at least equal to that normally attained for conventional gates with dual track support. Improved manual control mechanism for the locking pins provides in highly compact and reliable form independent operation either from inside the car or from outside through an open doorway.
