Abstract

PROBLEM TO BE SOLVED: To enable a person other than an operator of an overhead crane or the like to stop the overhead crane or the like in an instant by making not only the operator but also a sign sender and a worker carry transmitters of a device for receiving a stop signal from a radio transmitter and turning off a circuit breaker for wiring mechanically. SOLUTION: A transmitter bodies 9 of a power equipment emergency stop device are carried also by a sign sender 13 and a worker 14 besides an operator 15. When a danger is generated during work of an overhead crane 12, power equipment, the worker 14 recognizing the danger presses an emergency stop button of the transmitter body 9 carried himself. Then a stop signal is transmitted from the transmitter body 9 and received by a receiving part in a power interrupting device, and a circuit breaker 2 for wiring is turned off. The overhead crane 12 is thereby emergency-stopped by pushing the emergency stop button of the transmitter body 9 when the sign sender 13 or an optional worker feels danger. The worker himself can therefore bring the overhead crane 12 to an emergency stop in an instant to prevent a disaster.
