The present invention relates to a high-place operation car of a novel structure which can easily rotate a rotational beam to a predetermined home position. According to the present invention, the high-place operation car rotates a rotational beam (3) while a boom (5) is rotated, raised, and extended to allow a worker riding in a car (6) to approach a facility to work. Then when the worker operates an input means (40) to drive a drive motor (4) to rotate the rotational beam (3) to a home position, a control unit (30) receives a signal of a proximity detection means (20) to automatically stop operation of the drive motor (4) when the rotational beam (3) is rotated to the home position to accurately stop the rotational beam (3) at the home position. Therefore, when compared to a conventional high-place operation car wherein the worker must check a rotational state of the rotational beam (3) with naked eyes, work can be conveniently performed, and the car (6) can be accurately fixed at the predetermined position.

    본 발명은 회전대를 손쉽게 정해진 원점으로 회전시킬 수 있도록 된 새로운 구조의 고소작업차에 관한 것이다. 본 발명에 따른 고소작업차는, 상기 붐(5)을 회동상승 및 신장시킨 상태에서 상기 회전대(3)를 회전시켜 상기 카(6)에 탑승된 작업자가 설비에 근접되도록 하여 작업을 한 후, 상기 회전대(3)를 원점으로 회전시키기 위해 작업자가 상기 입력수단(40)을 조작하여 상기 구동모터(4)가 구동되도록 하면, 상기 제어유닛(30)은 상기 근접감지수단(20)의 신호를 수신하여, 상기 회전대(3)가 원점으로 회전되면 자동으로 상기 구동모터(4)의 작동을 정지시켜 회전대(3)가 원점에 정확히 정지되도록 한다. 따라서, 작업자가 육안으로 회전대(3)의 회전상태를 확인하여야 하는 종래의 고소작업차에 비해 작업이 편리할 뿐 아니라, 상기 카(6)가 정확히 정해진 위치에 고정되도록 할 수 있는 장점이 있다.
