PROBLEM TO BE SOLVED: To provide a high place work fall prevention device capable of ensuring a large work area of a worker and alleviating a pendulum phenomenon at a fall time.SOLUTION: The high place work fall prevention device includes: a support pillar 4 arranged in an erected state; a horizontal arm 5 movable in a horizontal plane with respect to the support pillar 4; a movement member 6 movable along the horizontal arm 5; connection means 32 connecting the movement member and a worker H; and a first drive mechanism 7 moving the horizontal arm 5. The high place work fall prevention device ensures a work area in a space. The movement member 6 includes a sensor unit 36 sensing swing of the connection means 32 due to movement of a worker H. Drive control means 50 is arranged which controls the first drive mechanism 7 to move the horizontal arm 5 in a direction for reducing the swing of the connection means 32 when an inclination angle of the connection means 32 sensed by the sensor unit 36 exceeds a threshold in a right/left direction of the horizontal arm 5.SELECTED DRAWING: Figure 4

    【課題】 作業者の広い作業エリアを確保でき、墜落時の振り子現象を軽減することができる高所作業用墜落防止装置を提供する。【解決手段】 起立状に配置された支柱4と、前記支柱4に対して水平面内で可動な水平アーム5と、前記水平アーム5に沿って移動可能となる移動部材6と、前記移動部材と作業者Hを連結する連結手段32と、前記水平アーム5を移動させる第1駆動機構7を有し、空間上の作業エリアを確保した高所作業用墜落防止装置である。前記移動部材6は、前記作業者Hの移動により、前記連結手段32の振れを検知するセンサーユニット36を備え、前記センサーユニット36により検知された前記連結手段32の傾斜角度が水平アーム5の左右方向へ閾値を超えると、前記水平アーム5を前記連結手段32の振れが小さくなる方向へ移動させるように前記第1駆動機構7を制御する駆動制御手段50を有する。【選択図】 図4
