This guidance explains the differences between ‘supplementary’ and ‘check’ couplers and gives typical design applications where high coupler forces could be expected and where additional loadbearing capacity to connections may be required. It also contains guidance on coupler configurations and expected safe working loads (SWLs) where supplementary couplers are used. To ensure that SWL values are as accurate as possible, data provided within this document is based on practical testing rather than calculation. 2 pages
This document provides guidance for covering 50mm gaps in scaffold platforms through which standards protrude, as well as for covering larger gaps in decking which, due to width restrictions or obstructions, cannot be fully boarded in the conventional way. This guidance is PDF only.
The effects of heat on scaffolding equipment can have a significant and permanent effect on its strength and performance. This guidance explains the potential issues and the action to be taken if equipment has been subjected to a fire or similar conditions. This guidance is available for pdf download only.
Scaffold tube storage racks are a common feature of every scaffolding contractor’s yard and many long-term live sites. Whilst tube racks are usually constructed as basic birdcage-like structures, they generally support many tonnes of equipment, so their design needs special consideration. This guidance note considers the design, use and maintenance of scaffold tube storage racks. 6 pages
