Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a mobile driver's cab device for a 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] At present, the driver's cab of cranes manufactured by various manufacturers is mainly fixed at one end of the main beam of the frame. This structure can meet the basic needs of equipment operation. However, during use, manufacturers have found the following shortcomings: for large-span cranes, since the driver's cab is fixed at one end, the driver's field of vision is poor, which makes it easy for operators to make mistakes and make it difficult to hoist into place. At the same time, most of the existing crane driver's cabs are fixed to the main beam by bolts, which is very troublesome during maintenance and replacement. Utility Model Content
