Problems solved by technology

[0004] The hoisting weight of the large section or the whole hole steel truss girder is heavy, and it is affected by the wind and waves at sea. The existing spreader structure is complex, its own weight is heavy, and the operation is difficult, which brings inconvenience to the construction and increases the construction cost.

Abstract

The invention relates to a lifting appliance for hoisting a large-section steel truss girder. The lifting appliance comprises a first beam, a first lifting lug group and pulley assemblies, wherein thefirst beam comprises a hoisting surface; the hoisting surface is used for being connected with a floating crane; the first lifting lug group is arranged on a surface, opposite to the lifting surface,of the first beam; and the pulley assemblies are arranged on the first lifting lug group and are used for being connected with the large-section steel truss girder. The lifting appliance is light inweight, and the effective lifting weight of lifting equipment can be effectively increased; and moreover, the lifting appliance is simple in structure and convenient to operate, the construction costis saved, and the construction efficiency is improved; and as the pulley assemblies are adopted to be connected with the large-section steel truss girder, the lifting appliance is convenient to install, disassemble and replacement.

Description

technical field [0001] The invention relates to the technical field of hoisting, in particular to a hoisting tool for hoisting large-segment steel truss girders. Background technique [0002] The Pingtan Strait Road-Railway Bridge is the first cross-strait road-railway bridge in my country. The Strait Bridge is different from the Bay Bridge built in the past. Its construction faces harsh conditions such as strong winds, high waves, surges, strong typhoons, and complex geology. The construction of the bridge brought great challenges and high risks. This bridge is the first attempt in the field of cross-strait bridges in China. Whether it is the harshness of the environment, or the technical challenges and construction risks it faces, it is far superior to other cross-sea bridges that have been built or are under construction in China. The Pingtan Strait Highway-Railway Bridge is the first time in the world to build a Strait Bridge in a complex wind and surge environment. Af...
