Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a crane beam used for a double-beam crane. Background Art

[0002] The characteristic of double-beam bridge crane is that it uses double beams to support the crane. The two ends of the double beams are connected to walking beams. The walking beams move to achieve longitudinal displacement, and the crane on the double beams moves laterally to achieve lateral displacement. The double-beam supported crane has the advantages of improving the walking stability of the crane and the advantage of large carrying capacity, in which the double beam is the main beam across the structure.

[0003] Most of the main beams of existing double-beam cranes are erected at high places, which makes it very troublesome to clean the main beam tracks and apply lubricating oil for maintenance. The work intensity is high and there is a certain degree of danger. At the same time, the spans of the two main beams of the existing double-beam cranes are mostly fixed. When different sizes of lifting trolleys are in operation, different main beams need to be replaced, which is relatively poor in practicality. Utility Model Content
