As explained above, in the present invention, a crane hook is provided with a pivot that projects laterally, and the top of the side-face chevron-shaped detachment prevention member is pivoted to the pivot, and in this pivoted state, the above-mentioned detachment occurs. The locking tip of one side of the stopper member extends to the locking surface inside the upwardly bent end of the crane hook, and the other side of the stopper member is used as a weight to hold the stopper member. The wire is hung on the crane hook by rotating and biasing the locking tip of one side of the rotationally biased retaining member to the locking surface inside the upwardly bent end of the crane hook. Since a long groove is provided on one side of the retaining member to allow the pivot to move freely along the longitudinal direction of the retaining member, it is possible to prevent wires hung on a crane hook, for example. When removing the device and hanging another hanging device on the crane hook, pull up the retaining member to move the pivoting device along the long groove, and place the locking tip of one side of the retaining member above the crane hook. The wire can be detached from the locking surface on the inside of the bending end, the wire can be removed from the crane hook, and another hanging device etc. can be hung on the crane hook.
After hanging this hanging tool, etc. on the crane hook, set the retaining member again and prevent the hanging tool, etc. hung on the crane hook from coming off, so that the retaining member remains attached to the crane hook at all times. In this state, sling work using wire hooks and work using hanging tools etc. can be alternately performed.
