Description

Technical Field

[0001] The invention relates to steel beam crane suspension assembly equipment and a construction method, belonging to the technical field of bridge construction. Background Art

[0002] China is still in the period of vigorously developing transportation infrastructure. There are three main ways to install steel beams: top-pushing, cantilever assembly, and bracket installation. At present, large-scale lifting equipment is still used in foreign countries to install steel beams. The main beam is hoisted to the designed position as a whole by a large-tonnage crane, and then the auxiliary structure is installed. This construction process has the advantages of rapid construction and high overall controllability. At the same time, it is limited by the site and beam height. Large floating cranes are still required in river-crossing areas, and the applicability is poor. In China, if the site meets the requirements and the existing lifting equipment meets the lifting conditions, cantilever assembly is used. In cases where there is no lifting equipment such as crossing the river, top-pushing is mainly used. The temporary facility project is large, so the cost is high.

[0003] In summary, the economic benefits of suspended assembly are higher, but there are more restrictions. Summary of the invention
