Description

Technical Field

[0001] The utility model belongs to the technical field of cranes, and in particular relates to a bridge crane with a wire rope lubrication function. Background Art

[0002] A bridge crane is a lifting equipment that is horizontally mounted above a workshop, warehouse, or material yard to lift materials. Its two ends are located on tall concrete columns or metal supports, and its shape is like a bridge. The bridge of the bridge crane runs longitudinally along the tracks laid on the elevated structures on both sides, so that the space under the bridge can be fully utilized to lift materials without being hindered by ground equipment. The lifting mechanism of the bridge crane lifts heavy objects by pulling the hook with a wire rope. However, the wire rope needs to be lubricated for maintenance during long-term use. Otherwise, the friction between the wire rope and the lifting drum or pulley will increase, and the wear of the wire rope will be more serious, which not only increases the workload of the lifting motor, but also reduces the service life of the wire rope. Replacing the wire rope increases the production cost. In the prior art, the staff lubricates the wire rope with a brush, which not only wastes lubricating oil, but also increases the workload of the staff and reduces production efficiency.
