[0002] During building construction, mobile support frames are often used for high-altitude operations. Currently, the support frames have problems of poor applicability and inconvenient movement. Although rollers have been added to the bottom of the support frames to facilitate movement, the stability of the support frames during the working state is insufficient while being easy to move. Even if side support rods are installed on the lower side of the frame body, sufficient stability cannot be guaranteed, and the operation is not convenient either.

Moreover, when moving, the counterweight boxes rise away from the ground, thus not affecting the passing performance of the whole device. Description of the Drawings
