To provide a suspension crane capable of easily and safely changing positions of a pair of lifting bodies included in a horizontally long suspension beam that is suspended and supported vertically movably and to which an object to be lifted is locked even when the object to be lifted is extremely heavy, and capable of easily and safely eliminating a bias of the load.SOLUTION: A suspension crane includes a horizontally long suspension beam 1 suspended and supported vertically movably and a pair of lifting bodies 2a, 2b respectively engaged to be mountable/removable at different positions of the suspension beam 1 and to which an object 13 to be lifted is locked. A plurality of engagement grooves 3 opened upward are formed in the suspension beam 1 to be arranged along a longitudinal direction of the suspension beam 1 and the lifting bodies 2a, 2b are engaged with any two engagement grooves 3.SELECTED DRAWING: Figure 2

    【課題】吊上対象物の重量が極めて大きい場合であっても、昇降可能に吊下げ支持され吊上対象物が係止される一対の吊上体を有する横長の吊ビームにおける該吊上体の位置が容易、かつ、安全に変更でき、荷重の偏倚の解消が容易、かつ、安全にできる吊り下げクレーンを提供すること。【解決手段】昇降可能に吊下げ支持される横長の吊ビーム1と、吊ビーム1の互いに異なる位置にそれぞれ着脱可能に係合され、吊上対象物13が係止される一対の吊上体2a、2bとを備え、吊ビーム1には、複数の上方に向けて開いた係合溝3が吊ビーム1の長手方向に沿って配列されて形成されており、何れか2つの係合溝3に吊上体2a、2bが係合されることを特徴とする吊り下げクレーン。【選択図】図2
