Claims (1)

[Scope of Claim for Utility Model Registration] (1) A main body is formed by providing a shaft pin insertion hole in a bifurcated vertical member with a hole for attaching a hanging wire in the upper part and a shaft pin insertion hole in a bifurcated vertical member for attaching a piece of the hanging member provided in the lower part, and the shaft pin insertion hole is formed in the bifurcated vertical member to which the suspension wire is inserted. A shackle pin is slidably inserted into the hole, and the shackle pin is pivoted to an arm that protrudes using an air cylinder built into the main body and rotates to return to its original position using a spring.A shackle is attached to the bottom of the control box. An air tank, power supply, and receiver are installed inside the control box. A chain is attached to the top of the control box to hang it from the jib of the crane. An air hose is connected to the air cylinder, and the air tank and air hose inside the control box are connected to each other. A shackle characterized in that the receiver is connected to the electromagnetic valve and the power source through an electromagnetic valve, and the receiver of the control box is combined with a wireless push button transmitter to remotely control the receiver. operating device. (2) A hole is drilled in the upper part to attach the suspension wire, and a shaft pin insertion hole is provided in the bifurcated vertical member to which the hanging member piece provided in the lower part is attached to form the main body, and the shaft pin can be slid freely into the shaft pin insertion hole. At the same time, a shackle formed by pivoting a shackle pin to an arm that rotates so as to be inserted and returned to its original position by an air cylinder built into the main body and projected by a spring is attached to the lower part of the control box, and an air tank is installed inside the control box. A power supply and receiver are installed inside the control box, a chain is attached to the top of the control box to hang it from the jib of the crane, an air hose is connected to the air cylinder, and the air tank inside the control box and the air hose are connected via a solenoid valve. , the receiver is connected to the electromagnetic valve and the power supply, and a display member is installed in one place of the control box that turns on and lights up, and a switch for the display member is installed in the place where the air cylinder is attached to the main body, so that when the shaft pin is pulled out, What is claimed is: 1. A control box operating device, characterized in that a wireless push-button transmitter is combined with a receiver of a control box in which a display member is actuated to cause a display member to rotate and light up, thereby remotely controlling the receiver.
