Description

Technical Field

[0001] The present application relates to the technical field of suspension bridge construction, and in particular to an extra-long hoisting scaffold for a main cable saddle at the top of a main tower. Background Art

[0002] The main saddle is usually hoisted by the cantilever gantry method. Under normal circumstances, the main saddle can be transported to the front of the main tower by a crane, and then the crane will lift the main saddle to the main tower. If the terrain restricts the main saddle, it cannot be transported directly to the front of the tower, and a hoisting platform needs to be set up for hoisting.

[0003] Regarding the above-mentioned related technologies, when there are terrain restrictions, it is necessary to set up a lifting platform, which increases the construction burden and reduces construction efficiency. Utility Model Content

[0010] Preferably, a plurality of reinforcing ribs are provided at the connection between the second support column and the second fixing plate.

[0011] By adopting the above technical solution, since the support column 2 will bear a large tensile force during lifting, reinforcing ribs are provided to increase the contact area between the support column 2 and the fixed plate 2, thereby improving the bearing capacity of the support column 2.

[0012] Preferably, a plurality of fixing ribs are provided at the connection between the fixing column and the second fixing plate.
