Problems solved by technology

Due to the different sizes and weights of the box girders, if a traditional single balanced hanging beam is used, it will not be able to meet the hoisting requirements. At the same time, there will be restrictions on the choice of cranes; if the single hanging beams are simply used in combination, the lifting stability will be reduced. Sexuality, increase potential safety hazards, and greatly increase construction costs

Abstract

The invention discloses a balance crane used for hoisting box girders of a steel bridge. The balance crane can accommodate different weights and special structures of box girders. The technical scheme includes that through combination of two balance crane parts and lifting lugs on the balance crane, hoisting stability is greatly improved, and the balance crane is applicable to various hoisting facilities such as big floating cranes and portal cranes; in different production and operation areas, the hoisting advantages can be used maximally, and problems of limited model selection of the balance crane and unbalance loading are avoided. In addition, lifting lugs in different size can be selected according to different specifications of box girders of the steel bridge, slings are reasonably distributed, and therefore different tons of box girders can be hoisted.

Description

technical field [0001] The invention relates to the field of hoisting of large steel structures, in particular to a balance hoisting beam used for hoisting steel bridge box girders. Background technique [0002] During the hoisting process, in order to maintain the balance of the hoisted components, reasonably distribute and balance the load of each hoisting point, and reduce the unbalanced load borne by the crane, it is very important to select or make a suitable balanced hoisting beam. Taking the Foss steel bridge project in Scotland undertaken by Shanghai Zhenhua Heavy Industries as an example, the typical segmental box girder length of this steel bridge is about 16.2m, the width is about 30.3m, the girder height is about 4.5m, and the total weight is about 200T. The lengths of box girders in special sections are 11.45m, 12.15m, 17.9m, 19.9m, etc., and the weight of a single box girder ranges from about 140T to 390T. Due to the different sizes and weights of the box gird...
