The present invention relates to a high-place work vehicle including a sensor for detecting a worktable holding state. A guardrail is provided on a worktable forming a workspace, and a high-place work vehicle is equipped with a sensor combined with a boom stand of the high-place work vehicle to the holding state of the worktable. The high-place work vehicle includes: at least one sensing part placed on the guardrail, and sensing whether a worker holds the guardrail; and a control part controlling the operation speed of at least one of the boom stand and worktable depending on whether the worker holds the guardrail through the sensing part. According to the present invention, if the guardrail is determined as being held through the sensing part, the high-place work vehicle increases the operation speed of the worktable and the boom stand. If the guardrail is determined as being released through the sensing part, the high-place work vehicle reduces the operation speed of the worktable and the boom stand or stops the operation while generating a warning signal. Therefore, the high-place work vehicle can prevent accidents by preventing workers from falling onto the ground due to the sudden operation or movement of the high-place work vehicle.

    본 발명은 작업대 파지상태 검출용 센서를 구비하는 고소작업차에 관한 것으로서, 작업공간을 형성하는 작업대에 난간이 구비되고, 고소작업차의 붐대 선단에 결합되어 작업대의 파지상태를 검출할 수 있는 파지상태 검출용 센서를 구비하는 고소작업차는 난간에 적어도 하나 이상 배치되며, 작업자가 난간을 파지하는지 여부를 센싱하는 센싱부; 및 센싱부를 통해 작업자의 난간 파지여부에 따라 붐대 또는 작업대 중 적어도 하나 이상의 구동속도를 제어하는 제어부;를 포함한다. 본 발명에 의하면, 센싱부를 통해 난간이 파지된 것으로 판단된 경우, 붐대 및 작업대의 구동속도를 증가시키고, 센싱부를 통해 난간이 파지되지 않은 것으로 판단된 경우, 경고신호를 생성하면서, 붐대 및 작업대의 구동속도를 감소시키거나 구동을 정지시킬 수 있어 고소작업자의 급작스러운 구동이나 이동에 의해 작업자가 바닥으로 추락하는 것을 방지하여 안전사고 발생을 막을 수 있다.
