ABSTRACT:
A device for interrupting the movement of load carrying units, such as carts or pallets, moving with a conveyor system. The device includes a movable conveyor engagement mechanism associated with each of the carts which is movable between a conveyor system engagement position and disengagement position by a movable actuator disposed at a first preselected location along the conveyor path at which the movement of a cart is to be interrupted. The movable actuator is controlled by a trigger mechanism disposed at a second predetermined location upstream of the movable actuator. The trigger mechanism is activated in response to a following cart moving with the conveyor past the trigger mechanism.
