The hands and the feet are separately controlled, so that the lifting control of the bearing frame 4 is more coordinated and easy to control. Meanwhile, as the initial state of the driving wheel 32 is locked, if the worker loses balance in the air and the foot leaves the brake pedal 364 in the lifting process, the brake lever 361 is reset immediately at the moment, the brake lever 361 is clamped and locks the driving wheel 32 to be incapable of continuing rotating, the bearing frame 4 stops lifting immediately, and the safety of aerial operation can be effectively guaranteed.
