Problems solved by technology

[0003] The weight of super-long bridge steel components often exceeds 100 tons, and because the crane cannot enter within the range of the obstacle, the crane can only be hoisted on both sides of the obstacle, resulting in an excessively large working radius of the crane and very high hoisting costs

Abstract

The hoisting method comprises the following steps that a, a first crane, a second crane, a steel beam component, a first temporary supporting frame body and a second temporary supporting frame body are arranged; b, the positions and the number of lifting lugs are arranged, and a first set of lifting lugs and a second set of lifting lugs are arranged; c, the first crane lifts the steel beam component through a first set of lifting lugs till the first crane translates to the limit working radius of the first crane, and the steel beam component temporarily falls on a first temporary supporting frame body; d, a second crane is buckled to one second set of lifting lugs, the first crane and the second crane are matched with each other, so that the first crane and the first set of lifting lugs are separated, and the first crane is buckled to the other second set of lifting lugs; and e, the first crane and the second crane synchronously hoist the steel beam component. And the hoisting system is converted, so that the specification of a selected crane is greatly reduced, and a large amount of crane cost is saved.

Description

Technical field [0001] The present invention relates to the technical field of lifting methods, in particular a lifting method. Background [0002] In current municipal and highway bridges, there is often a need to cross above-ground or underground barriers. Such as the upper span of the current situation of the river, highways, sedimentation ponds, underground shallow buried pipelines, military cables, etc., under the overhead high-voltage cables, existing bridges, etc., in the environment of the upper span of obstacles, such as the rainy season water flow is large, the highway with particularly busy traffic, the sedimentation pond that cannot be interrupted, the pipeline and military cable that cannot be changed or reinforced, etc., because of various use or operational requirements, it is impossible to set up temporary brackets above the obstacles, resulting in the use of ultra-long steel beam components to hoist the scheme of crossing the obstacles at one time. The length of...
