To provide a safety device of a high place working vehicle that can prevent workability in the vicinity of an obstacle from deteriorating.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. However, the safety device allows the working table 40 to move in the direction of approaching the obstacle S at a driving speed corresponding to an operation amount of an operation lever, when the detected distance detected by the distance sensor 55 is equal to or less than the set distance DS in a state where the operation amount is equal to or less than a preset threshold operation amount.SELECTED DRAWING: Figure 13

    【課題】障害物付近での作業性の低下を防止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う。但し、この安全装置は、操作レバーの操作量が予め設定された閾値操作量以下である状態で距離センサ55の検出距離が設定距離DS以下となった場合には、当該操作量に応じた駆動速度での作業台40の対象物Sへの接近方向の移動を許容する。【選択図】図13
