ーンあ安全装置。The crane front and tower front are recombinably assembled on the front part of the crane body, and there are switches for detecting overwinding of the main rope, auxiliary rope, and undulating opening, and a drum for winding each rope. It has a connector that connects with the relay that controls the upper operation stop solenoid in conjunction with the above-mentioned recombination, and includes a solenoid for stopping the auxiliary hoisting drum lowering operation and a solenoid for stopping the hoisting drum lowering operation in the event of an overload. In a safety device for a crane having a changeover switch for switching and connecting a solenoid, the changeover switch includes a buzzer for notifying an incorrect connection of the changeover switch, an auxiliary changeover switch that changes in conjunction with the changeover switch, and a buzzer that alerts the changeover switch when the changeover switch is connected incorrectly. A crane safety device comprising a connector and a signal line that connect to a power source via the auxiliary changeover switch.
