Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a telescopic bridge crane. Background Art

[0002] A bridge crane is a lifting device that is horizontally mounted above a workshop, warehouse, or material yard to lift materials. Because its two ends are located on tall concrete columns or metal brackets, it looks like a bridge. The bridge of a bridge crane runs longitudinally along the tracks laid on the elevated platforms on both sides, making full use of the space under the bridge to lift materials without being hindered by ground equipment. It is the most widely used and most numerous type of lifting machinery.

[0003] As disclosed in the authorization announcement number CN219058338U, a retractable bridge crane is disclosed, including an I-shaped main beam, the bottom surface of the main beam is provided with a movable walking beam through a first walking mechanism along its length direction, the movable walking beam is provided with a walking frame through a second walking mechanism, and the walking frame is provided with an electric hoist. In the retractable bridge crane of the utility model, the movable walking beam moves along the length direction of the main beam on the main beam under the drive of the first walking mechanism, and the walking frame and the electric hoist as a whole move on the movable walking beam under the drive of the second walking mechanism, realizing the retractable function, that is, realizing that when running to the limit range, the position of the electric hoist can exceed the range of the crane main beam, increasing the effective stroke of the crane, and the crane can be driven into the narrow space of the workshop, and the interference problem generated during the operation of the crane can be avoided. However, it has poor stability and short telescopic length during use. For this reason, we propose a retractable bridge crane to solve the problems of poor stability and short telescopic length of traditional devices. Utility Model Content
