  • Patent number: 5485791
    Abstract: A device for removing conveyor carriages from a conveyor-path region of an overhead conveyor in the event of an alarm, particularly in the region of a fire door. The overhead conveyor has a plurality of conveyor carriages received on a travel rail, a drivable pull line driven by a main drive for the conveyor carriages, and a plurality of drivers connected to the pull line, on each of which displaceable stop pawls are arranged. Within the conveyor-path region that is to remain clear, there is arranged in a fixed position a rail which acts upon the drivers as they pass the rail and in each case swings the stop pawl not in contact with the conveyor carriage into a non-driving position, so that upon the triggering of an alarm, although the overhead conveyor is stopped, a conveyor carriage present in the conveyor-path region can be moved out of conveyor-path region by an auxiliary drive which is also located in the conveyor-path region.
