To provide a runaway prevention device of a track running-type machine capable of surely providing a sufficient holding power which can withstand a load during a storm and capable of reasonably relieving an overload during a huge earthquake.SOLUTION: A runaway prevention device 11 of a container crane 1 (a track running-type machine) running on a rail 4 for cargo handling works comprises: a holding member 13 suspended swingably in the longitudinal direction of the rail 4 by parallel links 12a at a lower part of the container crane 1; a stopper 14 equipped on the holding member 13 so as to freely move up and down; a spring rod 15 (a resilient body) to connect in the expandable/contractible state between the holding member 13 and the lower part of the container crane 1 so as to hold the parallel link 12 in the suspended state; and base metals 16 arranged in multiple locations on the ground side along the rail 4 so as to specify the moving range of the container crane 1 by locking the stopper 14.SELECTED DRAWING: Figure 1

    【課題】暴風時の荷重に耐え得る十分な保持力が確実に得られ且つ巨大地震時の過荷重は無理なく逃がすことができる軌道走行式機械の逸走防止装置を提供する。【解決手段】レール4上を走行して荷役作業を行うコンテナクレーン1(軌道走行式機械)の逸走防止装置11に関し、コンテナクレーン1の下部に平行リンク12によりレール4の長手方向へ揺動自在に懸架された保持部材13と、該保持部材13に昇降自在に装備されたストッパ14と、平行リンク12を垂下した状態に保持するようコンテナクレーン1の下部と保持部材13との間を拡縮自在に連結するスプリングロッド15(弾発体)と、ストッパ14を係止せしめることでコンテナクレーン1の移動範囲を規定するようレール4に沿い地上側の複数箇所に配設された基礎金物16とを備える。【選択図】図1
