[0002] In coal mines, rails are commonly used for auxiliary transportation. With the continuous innovation of technology, monorail crane transportation has gradually matured. The safety and work efficiency of hanging heavy objects depend on the quality and installation position of the hanging longitudinal beam. The installation often requires manual work, which is labor-intensive. In particular, the monorail hanging longitudinal beam needs to be installed on the top of the tunnel. During the installation of the longitudinal beam, the heavy longitudinal beam needs to be lifted manually, which is inefficient, cumbersome and dangerous.
