Title: Animal facility equipment

Abstract: An animal facility, having a movable assembly and means for moving it along an alleyway, is equipped with means for emergency reversal of the direction of travel of the assembly at any point in its path of movement. The emergency reversal means comprises a stress balance means which normally remains in a balanced condition, but shifts to an unbalanced condition when the normal movement of the assembly is obstructed. The unbalanced condition is sensed; and actuating means responsive to the sensing is relied upon to effect reversal of travel.
