ABSTRACT:
An anti-tip device is useful for preventing a mobile storage system movable carriage from tipping. The anti-tip device includes an arm pivotable between inoperative and operative modes. In the inoperative mode, the arm hangs in an open position to permit the carriage to be placed on the system rails. With the carriage on the rails, the arm is pivotable to the operative mode wherein a hook on the arm slidingly engages an undercut surface of a longitudinal groove in the rail. The arm is pinned to the carriage when in the operative mode. A tipping force is resisted by contact between the pinned arm hook and the rail undercut surface.
