To provide a safety device for a high lift work vehicle that can keep a separation distance between a work table and a work object at a fixed distance, and can improve the safety and work efficiency of a worker when working while driving the vehicle.SOLUTION: The safety device for the high lift work vehicle comprises: work table separation distance detecting means for detecting a separation distance between a work table 40 that moved to a work position and a work object (e.g., a tunnel wall surface H) located on the side of the work table; and actuator control means for controlling the operation of a boom actuator so that the separation distance becomes a work set distance EL when the separation distance between the work table 40 and the work object changes due to the traveling movement of the vehicle.SELECTED DRAWING: Figure 3

    【課題】車両を走行させながら作業を行うときに、作業台と作業対象物との離隔距離を一定の距離に保つことができ、作業者の安全性および作業効率を向上させることができる高所作業車の安全装置を提供する。【解決手段】作業位置に移動した作業台40とその作業台の側方に位置する作業対象物(例えば、トンネル壁面H)との離隔距離を検出する作業台離隔距離検出手段と、作業台40と前記作業対象物との離隔距離が車両の走行移動により変化したときに、前記離隔距離が作業設定距離ELとなるようにブームアクチュエータの作動を制御するアクチュエータ制御手段とを備えて構成される。【選択図】図3
