Description

A kind of balance hanger for box girder

technical field

The utility model relates to the field of hoisting equipment, in particular to a balancing hoist for box girders.

Background technique

As the factory prefabrication technology of box girders becomes more and more mature, more work on the construction site is transferred to the prefabrication site, including the construction of anti-collision barriers. The integrated construction of box girders and anti-collision barriers has become a trend.

Due to the emergence of the integrated construction technology of box girder and anti-collision guardrail, box girder is generally divided into middle girder (box girder in the middle of the bridge) and side girder (box girder with anti-collision guardrail on both sides of the bridge). The cross-section of the middle beam is generally a symmetrical structure, and the size of the flange plates on both sides is the same; but the flange plate on the side beam side of the side beam cross-section is longer than that on the side of the middle beam, and the impact of the weight of the anti-collision barrier after the construction of the anti-collision barrier is added , which causes the center of gravity of the side beam to shift towards the side beam side.

At the same time, due to the change in the size of the flange plates on both sides of the side beam and the cross-sectional size of the crash barrier, the eccentricity is diverse.

In this way, when the box girder is hoisted, the inclination caused by the offset of the center of gravity of the box girder is very likely to occur, resulting in a safety accident.

So a hoisting device that can stably realize box girder hoisting is needed now.
