To provide a safety device of a high place working vehicle that can reduce a difference in a sense of a distance to an obstacle when regulating and stopping a working table.SOLUTION: A safety device performs control by which a working table 40 is stopped from moving in a direction of approaching an obstacle S, when a detected distance DK detected by a distance sensor 55 is equal to or less than a predetermined set distance DS. A set distance DS1 that is set when the working table 40 is moved toward the obstacle S by expansion/contraction actuation of a boom (driving of an expansion/contraction cylinder) and a set distance DS2 that is set when the working table 40 is moved toward the obstacle S by running actuation of a running body (driving of a running motor) can be set to different distances.SELECTED DRAWING: Figure 4
【課題】作業台を規制停止させたときの障害物との距離感の違いを軽減することのできる高所作業車の安全装置を提供する。【解決手段】安全装置は、距離センサ55において検出される検出距離DKが予め定められた設定距離DS以下となる場合に、作業台40の障害物Sへの接近方向の移動を停止させる制御を行い、ブームの伸縮作動(伸縮シリンダの駆動)により作業台40を障害物S側へ移動させるときに設定される設定距離DS1と、走行体の走行作動(走行モータの駆動)により作業台40を障害物S側へ移動させるときに設定される設定距離DS2とを異なる距離に設定可能である。【選択図】図4
