PROBLEM TO BE SOLVED: To reduce force applied to a runaway prevention layer apparatus so as to reduce the risk of runaway of a portal crane.SOLUTION: A portal crane 2 comprises: a pair of legs 8, 9 which are arranged being alienated from each other in a direction crossing a travelling direction of the portal crane 2; a girder 10 bridged between the legs 8, 9; and a runaway prevention device which binds lower parts of the legs 8, 9 with respect to the ground surface. In a method for fixing the portal crane 2, the lower parts of the legs 8, 9 are bound with respect to the ground surface by using the runaway prevention device. In a method for fixing the portal crane, ground surface side fixing parts 35, 36 that are arranged at the front side or the rear side in the travelling direction of the portal crane 2 are connected with the girder 10 or the legs 8, 9.SELECTED DRAWING: Figure 1

    【課題】逸走防止層装置に作用する力を軽減し、門型クレーンの逸走のおそれを低減する。【解決手段】門型クレーン2は、門型クレーン2の走行方向に交差する方向に離間して配置された一対の脚部8,9と、一対の脚部8,9に架け渡されたガーダ10と、脚部8,9の下部側を地面に対して拘束する逸走防止装置とを備える。門型クレーン2の固定方法では、逸走防止装置を用いて、脚部8,9の下部側を地面に対して拘束する。また、門型クレーンの固定方法では、門型クレーン2の走行方向の前方又は後方に設けられた地面側の固定部35,36とガーダ10又は脚部8,9とを連結する。【選択図】図1
