Description

Technical Field

[0002] The construction of high-speed railways at home and abroad is developing rapidly. The design of large-span bridges on high-speed railways mostly uses prefabricated segmental concrete beams in the beam yard, which are hoisted and transported by special hoists. This can greatly improve the construction speed of the bridge and reduce the labor intensity of the construction workers. In addition, there are a variety of different hoists that can be used for hoisting and transportation according to different construction conditions and the shape of the bridge, thereby improving its construction speed.

[0003] When some segmental concrete beams are hoisted and transported, they need to be rotated horizontally to adjust their angles so that they can be easily hoisted and transported. General hoists do not have this function, which causes certain troubles during hoisting and transportation. In addition, since the density of the segmental concrete beams cannot be guaranteed to be completely uniform during the production process, its center of gravity will change to a certain extent. Its stability cannot be guaranteed during hoisting and transportation, which is prone to safety accidents. In order to solve the above problems, a multifunctional hoist is urgently needed to solve the above problems. Utility Model Content
