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.

In a mobile storage system having a carriage and a plurality of wheels mounted thereon for rolling the carriage longitudinally along a fixed path, at least one anti-tip device for preventing tipping of the carriage comprising: a. a plurality of rails for supporting the carriage wheels, each rail defining a longitudinal groove having an undercut surface; b. bracket means for mounting to the carriage and defining an aperture therethrough having a longitudinal axis parallel to the direction of carriage motion; c. an anti-tip arm pivotally mounted to the bracket means for pivoting in a plane transverse to the direction of carriage motion along the rails, the anti-tip arm being formed with a first extension defining an aperture therethrough alignable with the aperture in the bracket means and a second extension defining a hook adapted to slide within the rail groove proximate the rail undercut surface when the arm and bracket means apertures are aligned; and d. a locking pin selectively insertable through the aligned apertures in the bracket means and arm first extension to thereby render the anti-tip arm operative by preventing the arm from pivoting about the bracket means and removable from the arm and bracket means apertures to thereby render the anti-tip arm inoperative by permitting the arm to pivot relative to the bracket means, so that when the anti-tip arm is in the operative mode a force tending to tip the carriage is resisted by the arm hook bearing against the rail undercut surface.
