Any damaged component must be removed, repaired or replaced. Also, this scaffolding is easy to assemble and dismantle, which makes it easy for users to transport and store it. About 50% of these are Scaffoldings, 25% are Ladder & Scaffolding Parts, and 2% are Work Platforms. Close boarding, netting and sheeting must be used to prevent objects from falling onto anyone below. The boards also prevent the possibility of people slipping off the edge of the platform. These can be used between the standards or can be used between the internal standard and wall, providing a platform that is closer to the area of work and not reducing the width of the standard platform. Platforms must not deflect more than 1/60 of the span when loaded. How to calculate scaffolding load. It is also known as putlog scaffolding.. These are the pipes that make up the … Install scaffold with jackscrews (adjusting screws). Scaffold supported … Don't load the scaffold with more weight than it can safely handle. To aid the flow of work, ‘hop-up’ scaffolding units can be used to increase the height that the workforce can access at each lift. When scaffolding is positioned in areas accessed by pedestrians it is necessary to use high visibility warning tape and lighting. So a 10 foot span(120 inches) cannot deflect more than: 2 inches.
