The present invention relates to a horizontal control method of a worktable provided in an aerial vehicle, which comprises the following steps of: maintaining a level of the worktable while driving a derrick cylinder, a master cylinder, and a leveling cylinder; checking an inclination of the worktable through a horizontal sensor attached to the worktable; and additionally adjusting the level of the worktable by supplying an additional hydraulic pressure to the leveling cylinder in which the inclination of the worktable exceeds a preset range. According to the present invention, the derrick cylinder, the master cylinder, and the leveling cylinder are used to precisely control the level of the worktable through the horizontal sensor and an inclination sensor. Therefore, a stable working environment can be provided to a worker working on the worktable.

    본 발명은 고소작업차량에 구비되는 작업대의 수평제어방법에 관한 것으로서, 데릭실린더, 마스터 실린더 및 레벨링 실린더를 구동시키면서 작업대의 수평을 유지하는 단계; 및 작업대에 부착된 수평센서를 통해 상기 작업대의 기울기를 확인하는 단계; 및 직업대의 기울기가 기설정된 범위를 초과하며, 레벨링 실린더에 유압을 추가 공급하여 작업대의 수평을 추가 조정하는 단계;를 포함한다. 본 발명에 의하면, 데릭실린더, 마스터 실린더 및 레벨링 실린더를 통한 작업대의 수평과 기울기 센서를 통한 추가적인 미세하게 작업대의 수평상태를 정밀하게 제어함으로써 작업대에서 작업하는 작업자에게 안정적인 작업환경을 제공할 수 있다.
