Abstract
PURPOSE: To detect breakage of chain by use of an actuator plate which is attached to a rod on the side of a breakage detecting chain and is designed to kick a limit switch provided on the side wall of cylinder.
CONSTITUTION: When lift chain 5 is broken, member 10 of cabin drops at first and breakage detecting chain 6 having one end connected to bracket 11 is pulled and compression spring is further compressed, whereby rod 12 is pushed upward. At the same time, actuator plate 14 carried on the rod 12 is also moved upward, so that lever of limit switch 15 attached to cylinder 2 is kicked up, thereby detecting that lift chain 5 is broken.
