To provide a safety device for a high-lift work vehicle capable of improving work efficiency by widening a work range as much as possible while maintaining safety with respect to a vehicle traveling in an adjacent lane.SOLUTION: A safety device for a high-lift work vehicle regulates the operation of a boom actuator in which the tip of a boom 20 moves outward beyond a vertical regulation surface SV when the position of the tip of the boom 20 is higher than a height regulation value SH. It also performs control to allow the operation of a work table turning motor (a swing motor that swings a work table 40 with respect to the tip of the boom 20) in which the work table 40 moves outward beyond the vertical regulation surface SV.SELECTED DRAWING: Figure 7

    【課題】隣の車線を通行している車両に対する安全性を保ちつつ、作業範囲を極力広くして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】ブーム20の先端部の位置が高さ規制値SHよりも高い位置にあるときは、ブーム20の先端部が垂直規制面SVを超えて外方に移動するブームアクチュエータの作動を規制する一方、作業台40が垂直規制面SVを超えて外方に移動する作業台旋回モータ(作業台40をブーム20の先端部に対して旋回作動させる旋回モータ)の作動を許容する制御を行う。【選択図】図7
