Abstract

PURPOSE: To prevent a large slack of a load chain, when a cargo is slung down to a prescribed position by winding-down operation to cause a slight slack to the load chain, by operating a switch for stopping the winding-down operation. CONSTITUTION: A switch operation member 2 connected to the suspended lower end of a load chain 1 is elevatably fitted to the upper part of a support member 4 equipped with a hook 3 at its lower part, and a switch 6 for stopping the winding-down operation arranged to the lower part of the switch operation member 2 with which a depressing spring 5 is engaged is fixed to the support member 4. In this constitution, winding-down operation is carried out by hanging a cargo to the hook 3, and when the cargo is lowered on a receiving table and a slight slack is caused to the load chain 1, the switch operation member 2 is depressed by the depressing spring 5, and the switch 6 for stopping the winding-down operation is operated by the switch operation member 2 to immediately stop the winding-down operation.
