PROBLEM TO BE SOLVED: To provide a lifting unit and a dredging system using the lifting unit, and a lifting method and a dredging method using them; which is low-cost and has superior work efficiency and measurement accuracy even being small in scale.SOLUTION: A lifting unit 100 in the present invention comprises: a main lifting device 2 which is lifted down in an almost horizontal posture from a crane 5; a main-body holding part 101 which holds a main body 102 to be lifted and is capable of adjusting own floatation by a main-body ballast tank 24; an intermediate lifting device 3, which is located between the main lifting device 2 and the main-body holding part 101, and is capable of adjusting floatation by an intermediate ballast tank 20; and a folding-and-extending structure 14, in which connection wires 10, 11 are folded with use of restricting wires 8, 9 and are inserted at least either between the main-body holding part 101 and the intermediate lifting device 3 or between the main lifting device 2 and the intermediate lifting device 3, for extending the connection wires 10, 11, the restricting wires 8, 9 are disconnected at a low-tension state, then the connection wires 10, 11 are arranged almost parallel with each other by raising the main lifting device 2 and the intermediate lifting device 3 leaving the main-body holding part 101 and the intermediate lifting device 3 at the water surface 59.SELECTED DRAWING: Figure 1

    【課題】小規模でありながら、低コストで、作業効率や測定精度に優れた、吊下げ装置、それによる浚渫装置、それによる吊下げ方法、浚渫方法を提供することを目的とする。【解決手段】本発明を適用した吊下げ装置100は、起重機5に略水平に吊下される主吊具2と、吊下対象の本体部102を保持し本体用バラストタンク24で浮沈調整可能な本体保持部101と、主吊具2と本体保持部101間にあって中間用バラストタンク20で浮沈調整可能な中間吊具3と、本体保持部101と中間吊具3間、主吊具2と中間吊具3間の少なくとも一方に、連結ワイヤ10、11を規制ワイヤ8、9によって折り畳み状態で介設し、連結ワイヤ10、11展開時は、規制ワイヤ8、9を低張力状態で取り外し後、本体保持部101や中間吊具3を水面59に残したまま主吊具2や中間吊具3を上昇させ、連結ワイヤ10、11を互いに略平行に並設する折り畳み展開構造14とを備える。【選択図】図1
