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. |
