To quickly set a suspended load in a horizontal state.SOLUTION: A suspension apparatus 100 comprises: four or more suspension ropes 10 extending from a crane suspension tool 1 toward a suspended load 2; a chain block 20 that is provided for each suspension rope 10 and that adjusts a distance between a first load point P1 at which a load of the suspended load 2 is applied on the suspension rope 10 and a second load point P2 at which the load of the suspended load 2 is applied on the suspension tool 1 via the suspension rope 10; an inclination angle measurement device 30 that measures the inclination angle of the suspended load 2 with respect to a horizontal surface; and a control device 40 that adjusts the attitude of the suspended load 2 by controlling the chain block 20 on the basis of the inclination angle measured by the inclination angle measurement device 30. The control device 40 selects one reference suspension rope serving as a reference from among the suspension ropes 10 on the basis of the heights of a plurality of first load points P1 in a vertical direction, and simultaneously activates all chain blocks 20 other than a chain block 20 provided to the reference suspension rope to adjust the attitude of the suspended load 2.SELECTED DRAWING: Figure 3

    【課題】吊荷を迅速に水平な状態とする。【解決手段】吊装置100は、クレーンの吊具1から吊荷2に向かって延びる4つ以上の吊索10と、吊索10毎に設けられ、吊索10に対して吊荷2の荷重が作用する第1荷重点P1と吊荷2の荷重が吊索10を介して吊具1に作用する第2荷重点P2との間の距離を調整するチェーンブロック20と、水平面に対する吊荷2の傾斜角を計測する傾斜角計測装置30と、傾斜角計測装置30で計測された傾斜角に基づいてチェーンブロック20を制御することにより吊荷2の姿勢を調整する制御装置40と、を備え、制御装置40は、複数の第1荷重点P1の鉛直方向における高さの高低に基づいて吊索10の中から基準となる基準吊索を1つ選定し、基準吊索に設けられたチェーンブロック20を除く他の全てのチェーンブロック20を同時に作動させて、吊荷2の姿勢を調整する。【選択図】図3
