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
【課題】簡単な構成でありながら、長尺状の吊上対象物を起立させて吊り上げることができるように構成された吊り具を提供する。【解決手段】吊り具は、ワイヤ側吊り具30を、被係合テーパ部32bが下方に突出するとともにストレート部32aが挿抜空間12a内に位置するまで、上方から挿抜空間に挿入可能、且つ、回転部材20を受容回転位置に位置させた状態で、挿抜空間内に位置したストレート部を係合空間に横方向移動させることが可能な構成であり、ストレート部が係合空間内に移動した状態から被係合テーパ部を上動させると被係合テーパ部が係合空間内で回転部材と上下に係合するように構成されており、被係合テーパ部が係合空間内で回転部材と上下に係合した状態で、対象物側吊り具10とワイヤ側吊り具が連結してキャリア装置により掘削装置Tを吊上可能となり、且つ、ワイヤ側吊り具は回転部材と一体となって受容部材に対して回転可能である。【選択図】図8
