To provide a safety device of an aerial work platform vehicle capable of improving the safety in work.SOLUTION: A safety device of an aerial work platform vehicle includes a winch load calculation unit 205 detecting a winch load acting on a winch mechanism (a winch driving motor 78) through a rope and a winch operation regulation unit 206 regulating winding operation of the winch mechanism when the winch load detected by the winch load calculation unit 205 exceeds a regulation load set in advance. The regulation load is set to a winch load in the case where a vehicle body does not fall down even when the tensile force in an outward direction having a horizontal component (for example, the tensile force outward in an obliquely downward direction) acts on the rope through the winding operation of the winch mechanism.SELECTED DRAWING: Figure 4

    【課題】作業の安全性を向上させることが可能な高所作業車の安全装置を提供する。【解決手段】高所作業車の安全装置が、ロープを介してウインチ機構(ウインチ駆動モータ78)に作用するウインチ荷重を検出するウインチ荷重算出部205と、ウインチ荷重算出部205により検出されたウインチ荷重が予め設定された規制荷重を超えるとウインチ機構の巻き取り作動を規制するウインチ作動規制部206とを備え、規制荷重は、ウインチ機構の巻き取り作動により水平方向成分を有する外側方への引張力(例えば、斜め下方向の外方への引張力)がロープに作用しても車体が転倒しない場合のウインチ荷重に設定される。【選択図】図4
