The present invention relates to an aerial work platform provided with a safety device, wherein the aerial work platform can be elevated by an elastic cylinder. A flange having an air passage is coupled to a lower end unit of a pneumatic cylinder, and a hydraulic cylinder is integrally coupled to a central support unit of the flange, and a main pillar and a safety pillar are doubly formed inside and outside to support a work platform by having multiple pneumatic cylinders to be coupled to the hydraulic cylinder. According to the present invention, a work place is doubly supported by the main pillar elongated by the pneumatic pressure and the safety pillar elongated by the hydraulic pressure, and the safety of the work place is guaranteed by the safety pillar if a safety problem occurs on the main pillar, thereby enhancing safety, usability and convenience of the aerial work platform.

    본 발명은 안전장치가 구비된 고소 작업대에 관한 것으로 신축성 실린더에 의해 작업대를 승강 하게 된 것에 있어서, 공압 실린더의 하단부에 공기 통로가 형성된 플랜지가 체결되고 상기 플랜지의 중앙 지지부에 액압 실린더가 일체로 결합되며, 복수의 상기 공압 실린더와 상기 액압 실린더가 결합되어 작업대를 받치는 매인지주와 안전지주가 내외 이중으로 구성된 것이다. 본 발명에 의하면, 작업대가 공압에 의해 신장된 매인지주와 액압에 의해 신장된 안전지주에 의해 이중으로 보강 지지되고 매인지주에 안전문제가 발생되면 안전지주에 의해 작업대의 안전성이 보장되어 고소 작업대의 안전성과 유용성과 편리성이 보다 증대하게 된 것이다.
