To provide a track travel type machine capable of preventing damaging of a travel device or a rail clamp device and deformation of a rail when an earthquake occurs with a simple structure.SOLUTION: This track travel type machine is provided with: a base plate 40 that is attached to a travel device 8 so as to be orthogonal to a traveling direction; a support plate 60 that is attached to the base plate 40 so as to freely oscillate about the traveling direction via a first connection mechanism 50; a support bracket 70 that projects from the support plate 60 in the traveling direction; and a projection bracket 90 that projects from a rail clamp device 30 in the traveling direction and that is connected to the support bracket 70 via a second connection mechanism 80. The second connection mechanism 80 is broken when a load exceeding a set load is applied in the traveling direction when the earthquake occurs.SELECTED DRAWING: Figure 2

    【課題】簡単な構造で、地震発生時における走行装置やレールクランプ装置の損傷並びにレールの変形を回避し得る軌道走行式機械を提供する。【解決手段】走行方向に対し直交するよう走行装置8に取り付けられるベースプレート40と、ベースプレート40に対し第一連結機構50を介し走行方向を軸として揺動自在に取り付けられる支持プレート60と、支持プレート60から走行方向へ張り出す支持ブラケット70と、レールクランプ装置30から走行方向へ張り出し且つ支持ブラケット70に対し第二連結機構80を介して連結される張出ブラケット90とを備え、第二連結機構80は、地震発生時に設定荷重を超える負荷が走行方向へ作用した場合に破断する。【選択図】図2
