To provide a rail brake device for a cargo handling machine which enables reduction of a construction period and a design period.SOLUTION: A rail brake device 50 installed at a cargo handling machine 1 including travel devices 30 each of which may drive along a rail 200 installed on the ground, includes: a rail brake body 60 which presses a brake pad 62, which reciprocates in a vertical direction following motion of a fluid pressure cylinder 61, to an upper surface 201 of the rail to put a brake on the cargo handling machine; a fluid pressure circuit 80 for causing the fluid pressure cylinder to operate; an acceleration sensor 70 which outputs an acceleration signal generated according to an acceleration speed of the cargo handling machine; and a control unit 51 which outputs a control signal based on the acceleration signal from the acceleration sensor. The fluid pressure circuit includes a valve mechanism 81 which is controlled by the control signal to adjust an amount of a working fluid in pressure chambers of the fluid pressure cylinder. The acceleration sensor is installed to detect an acceleration speed in at least a travel direction of the cargo handling machine.SELECTED DRAWING: Figure 5

    【課題】工事期間や設計期間を短縮することが可能な荷役機械用レールブレーキ装置を提供する。【解決手段】地上に敷設されたレール200に沿って走行可能な走行装置30を備えた荷役機械1に設置されるレールブレーキ装置50であって、流体圧シリンダー61の動作に従動して鉛直方向に往復運動するブレーキパッド62をレールの上面201に押圧させて荷役機械に制動を掛けるレールブレーキ本体60と、流体圧シリンダーを作動させるための流体圧回路80と、荷役機械の加速度に応じた加速度信号を出力する加速度センサー70と、加速度センサーからの加速度信号に基づいて制御信号を出力する制御部51と、を備え、流体圧回路は、制御信号によって制御されて、流体圧シリンダーの圧力室内の作動流体の量を調整するための弁機構81を含み、加速度センサーは、少なくとも荷役機械の走行方向の加速度を検出するように設置されている。【選択図】図5
