To provide a brake device for a track travel type machine that is able to adjust an operating-fluid-pressure increase speed of a hydraulic cylinder while increasing an operating speed by reducing a time of contact of a brake pad with a travel rail, and is able to relieve a load on the track travel type machine by suppressing a sudden brake.SOLUTION: A brake device for a track travel type machine includes: a branch line 480 branching from a certain point of a supply/discharge line 431 connecting a fluid pressure unit 430 and a fluid pressure cylinder 420; a buffer accumulator 481 connected to the branch line 480; and a flow rate control valve 482 provided at a certain point of the branch line 480.SELECTED DRAWING: Figure 2

    【課題】ブレーキパッドの走行レールに対する接触時間を短縮して動作速度を高めつつ、流体圧シリンダの作動流体圧上昇速度を調節し得、急激な制動を抑えて軌道走行式機械への負荷を緩和し得る軌道走行式機械の制動装置を提供する。【解決手段】流体圧ユニット430と流体圧シリンダ420とをつなぐ給排ライン431途中から分岐する分岐ライン480と、分岐ライン480に接続される緩衝用アキュムレータ481と、分岐ライン480途中に設けられた流量制御弁482とを備える。【選択図】図2
