(2) The arm rotatably supports a rotary support shaft that is integral with the workbench, and the brake is a band brake that is coupled to the arm and restrains a drum that is integral with the rotary support shaft. A work platform horizontal maintenance device for an aerial work vehicle as set forth in claim 1 of the utility model registration claim. (3) The arm rotatably supports a rotary support shaft that is integral with the workbench, and the brake is a disk brake that is coupled to the arm and restrains a disk that is integral with the rotary support shaft. A work platform horizontal maintenance device for an aerial work vehicle as set forth in claim 1 of the utility model registration claim. (4) The releasing means includes a cylinder whose hydraulic pressure is controlled to operate the brake as the arm is raised and lowered. A work platform horizontal maintenance device for an aerial work vehicle as described in the above.
