PROBLEM TO BE SOLVED: To provide a hoisting accessory that can hoist a long-sized object to be hoisted in a raised state although having simple constitution.SOLUTION: A hoisting accessor is characterized in that a wire-side hoisting accessor 30 has an engaged tapered part 32b projected downward, a straight part 32a can be inserted into an insertion/extraction space 12a from above until it is located in the insertion/extraction space, and while a rotary member 20 is located at a reception rotational position, the straight part located in the insertion/extraction space can be moved horizontally to an engagement space. When the straight part moves the engaged tapered part having been moved into an engagement space upward, the engaged tapered part is configured to engage a rotary member vertically in the engagement space. While the engaged tapered part engages the rotary member vertically in the engagement space, an object-side hoisting accessor 10 and the wire-side hoisting accessor are coupled to each other and then can hoist an excavator T by a carrier device, and the wire-side hoisting accessory is united with the rotary member in one body and can rotate with respect to a receiving member.SELECTED DRAWING: Figure 8 |
