Technical briefing on hoisting safety of steel structure components

Summary of safety technical briefing on hoisting steel structure components
Correction columns without cable wind ropes should be calibrated as they are hoisted. However, if the eccentricity is large, slender, and/or the depth of the cup mouth is less than the length of the column, it is prohibited to enter the site without cable wind rope correction. You must wear a safety helmet, fasten the hat strap, and use personal protective equipment correctly.
Special racks should be used for structural components that are easy to collapse. After unloading, they should be placed firmly and firmly supported to prevent collapse.
When components are directly lifted and unloaded on the floor of the engineering structure, overload stacking is strictly prohibited.
Erection workers, lifting drivers, commanders, and other lifting workers must hold special operation certificates to work.
Before installation, check whether the mechanical rigging, clamps, lifting rings, etc. meet the requirements and conduct a trial lifting.
There must be a unified command and unified signal during installation.
When the hanging roof truss is raised from the inside to the outer panel, the hook should be lifted first to stabilize and cooperate with the telescopic arm. When the hanging roof truss is lifted from the outside to the inner panel, the arm should be extended first to cooperate with the hook. In any case, operations must be carried out only after the crane legs are extended and supported firmly.
Extend the arms without extending the outriggers. The roof trusses at
should be placed on pre-embedded iron plates, with no less than three diagonal braces on both sides, and should be welded in time with the cooperation of welders. Leaning on pillars is prohibited.
Introduce the pillar into the mouth of the cup. Place the cross axis at the mouth of the cup in advance to align it. The lifting point rod should be pried back. Two wedges are needed on each side to temporarily fix the column. The hook should be hammered tightly before loosening the hook.
The wind rope correction posts should be calibrated as they are hoisted. However, when the eccentricity is large, slender, and the depth of the cup opening is less than the length of the column/or is insufficient, uncable wind rope correction is prohibited.
It is forbidden to place any objects on plate-shaped and other components for lifting.
When installing components that are difficult to place stably, use snap rings instead of hooks directly.
When installing roof panels and floor panels, it is prohibited to stack sheets on the structural floor with excessive load.
In the event of severe weather such as heavy rain, fog, snow or gusty winds above level 6, operations must be stopped immediately.
Implement the ten rules of not lifting
Do not lift if the lifting command signal is unclear
Do not lift if the load is overloaded
Do not lift if the workpiece is not fastened firmly
No one is on the lifting object. Hoisting
Do not lift if the safety device is not working
Do not lift if the workpiece is buried underground
Do not lift if the workpiece is diagonally pulled
Do not lift if the light is dark and cannot be seen clearly
Small accessories or short materials Don’t hang it if it’s overfilled
Don’t hang it if corners are not protected by padding or other corner protection measures.
