PROBLEM TO BE SOLVED: To provide a bridge crane which achieves weight reduction and slides on the ground or a rail to move without using a travel device needing high manufacturing costs.SOLUTION: A bridge crane includes: a skid platform 31 disposed on a lower end surface 12 of an understructure 10; wire ropes 32, 33 which are connected with a lower end part of the understructure 10 and extend in a y1 direction and a y2 direction which are perpendicular to a moving direction of a trolley 23; and a winch 34 which pulls the wire ropes 32, 33. One of the wire ropes 32, 33 is selectively pulled by the winch 34.

    【課題】製造コストの高い走行装置を用いずに、軽量化すると共に、地盤上又は軌条上を滑動して移動する橋形クレーンを提供する。【解決手段】下部構造体10の下端面12に配置される滑り材31と、下部構造体10の下端部に接続されてトロリ23の移動方向と直交するy1方向、y2方向のそれぞれに向かって延設されたワイヤロープ32、33と、これらワイヤロープ32、33を引っ張るウインチ34とを備え、このウインチ34によってワイヤロープ32、33のいずれか一方を選択的に引っ張ることができる構成である。【選択図】図2
