To provide a coupling assist device for a derricking body capable of performing assembly work of the derricking body by easily coupling a plurality of component members included in the derricking body.SOLUTION: A coupling assist device 40 assists the coupling of a first upper connector 16A of a first intermediate boom 16 and a second upper connector 18A of a second intermediate boom 18 that are included in a boom 12. The coupling assist device 40 includes a boom mounting part 46 mounted on a first upper main frame 161 of the first intermediate boom 16 and a connector guide 47. The connector guide 47 is abutted on a second plate-like part 18P of the second upper connector 18A to guide the second plate-like part 18P to a coupling preparation position in association with the descending of the second intermediate boom 18. Thereafter, hole parts of the first upper connector 16A and a first lower connector 16B are made to match each other in association with the descending of the second plate-like part 18P.SELECTED DRAWING: Figure 11

    【課題】起伏体を構成する複数の構成部材同士を容易に連結しながら、起伏体の組み立て作業を行うことが可能な起伏体の連結補助装置を提供する。【解決手段】連結補助装置40は、ブーム12をそれぞれ構成する第1中間ブーム16の第1上コネクタ16Aと第2中間ブーム18の第2上コネクタ18Aとの連結を補助する。連結補助装置40は、第1中間ブーム16の第1上メインフレーム161に装着されるブーム装着部46と、コネクタガイド47と、を有する。コネクタガイド47は、第2上コネクタ18Aの第2板状部18Pに当接し、第2中間ブーム18の下降に伴って第2板状部18Pを連結準備位置まで案内する。その後、第2板状部18Pが下降することで、第1上コネクタ16Aおよび第1下コネクタ16Bの孔部同士が互いに合致する。【選択図】図11
