PROBLEM TO BE SOLVED: To preferably move a bridge crane in a front/rear direction and a left/right direction by transferring at a rail intersection part.SOLUTION: A bridge crane 1 includes an upper beam 2 having a suspension mechanism 5 and extending in a left/right direction, left/right and front/rear leg parts 3 supporting the upper beam 2, and a wheel unit 4 including one or plural wheels mounted on a lower end of each leg part 3 and traveling on a rail. The bridge crane 1 further includes a jack-up device 20 and a wheel unit turning device 10 on each leg part 3. The jack-up device 20 lifts the wheel unit 4 from the rail by a butting operation against a jack-up receiver 30. The wheel unit turning device 10 turns the wheel unit 4 during jack-up and adjusts to the orientation of a rail to be changed.SELECTED DRAWING: Figure 1

    【課題】 橋形クレーンをレール交差部での乗り換えにより前後方向及び左右方向に好適に移動させる。【解決手段】 橋形クレーン1は、懸架機構5を有して左右方向に延びる上梁2、上梁2を支持する左右前後の脚部3、及び、各脚部3の下端に装備されてレール上を走行する1乃至複数の車輪からなる車輪ユニット4を備える。橋形クレーン1はまた、各脚部3に、ジャッキアップ装置20と車輪ユニット旋回装置10とを備える。ジャッキアップ装置20は、ジャッキアップ受台30への突き当て動作により、車輪ユニット4をレールから浮かせる。車輪ユニット旋回装置10は、ジャッキアップ中に、車輪ユニット4を旋回させて、乗り換えるレールの向きに合わせる。【選択図】 図1
