Abstract

The utility model relates to the technical field of lifting devices and proposes an adjustable lifting device. By combining a longitudinal lifting beam with a distal transverse lifting beam, multiple lifting points are distributed at different positions on the arch steel beam. This greatly reduces the shaking caused by the arch steel beam's curved shape and long length during the lifting process, thereby improving the stability of the lifting process. The slidable connection design between the steel crossbeam and the slide plate allows for rapid lateral adjustment of the lifting point position, controlling the lateral movement of the arch steel beam and effectively reducing the number of lifting operations.
