Due to thermal expansion or contraction during the welding process, the position of the lower beam may shift, resulting in inaccurate connection with other components, affecting the stability and safety of the overall structure of the elevator. Therefore, we proposed an elevator lower beam welding positioning device. Utility Model Content

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:
