Its metal structure is like a door-shaped frame, with two supporting legs installed under the load-bearing main beam.
[0003] When adjusting the position of an existing gantry crane, workers are required to continuously measure the movement distance of the two struts to ensure the smooth movement of the gantry. The operation steps are complicated, measurement errors are prone to occur, and there are certain safety hazards. In addition, when adjusting the position of an existing gantry crane, the gantry crane is moved by rollers set at the bottom, and solids are placed on both sides of the rollers for limiting the position. This positioning method is not stable enough and the gantry crane is prone to displacement. Utility Model Content
