After the first towing of 1 ~ 2m, the deformation of the frame shall be checked to confirm that there is no deformation before the formal towing. After the towing and positioning, the scaffold shall be fully checked for deformation and inertia, and can be used only after confirming no deformation.

Net frame steel bolt ball, rod and other components, should be hoisted to the scaffold platform in batches. It shall not be piled up on the shelf platform in large quantities at one time.

Scaffold platform operators should be reduced as far as possible, the operation should not be more than one person in a span of scaffolding.
