If there is a gap between the fixed base and the fixed side seat, it will cause a certain distance gap between the fixed column and the fixed socket of the counterweight block. The proximity switch will not send a signal to the external control device. In this case, the external control device will not control the start of the lifting equipment, thereby ensuring that the inspection operation will only be performed when the hanger and the counterweight block are firmly fixed, to prevent the counterweight block from falling off due to loose fixation between the hanger and the counterweight block, causing a safety accident.

[0014] Through the setting of the fixed slider and the fixed plug, by pulling the fixed plug to one side, the fixed plug will be disengaged from the fixed slot of the fixed slider. At this time, the fixed slider can be replaced, which facilitates the subsequent maintenance and overhaul of the device and greatly improves the speed of maintenance and replacement.

[0028] The specific usage and function of this embodiment: When inspecting the crane sling, first insert the fixing pin 309 into the connecting socket 205, and then insert the fixing pin 309 through the connecting socket 205 into the fixing socket of the counterweight block 103, so that the appropriate number of counterweight blocks 103 can be selected for inspection according to the inspection needs, and then the sling 2 is lifted by the lifting ear 202 for load inspection.

[0029] When the fixed column 309 is fully inserted into the fixed socket of the counterweight block 103, such as the fixed base 203 and the fixed side seat 3 are fully fitted, the detection block 311 will first contact the side of the fixed base 203, the detection block 311 will move backward, and the rear end of the detection block 311 will touch the proximity switch 312, the proximity switch 312 will be triggered, and the proximity switch 312 will send a signal to the external control device.
