  • Cause Analysis of Scaffolding Deformation Accidents

    1. When the scaffold is unloaded or the tensioning system is partially damaged, immediately repair it according to the unloading method formulated in the original plan, and correct the deformed parts and rods. If the deformation of the scaffold is corrected, set up a 5t reverse chain in each bay ...

  • The overall stability of scaffolding

    Scaffolding may have two types of instability: global instability and local instability. 1. Overall instability When the whole is unstable, the scaffold presents a horizontal frame composed of inner and outer vertical rods and horizontal rods. The large wave bulges along the direction of the vert...
