BS 1139-6:2014 Metal scaffolding. Prefabricated tower scaffolds outside the scope of BS EN 1004, but utilizing components from such systems. Specification
BS 1139-6:2014 specifies requirements for the structural design of prefabricated tower scaffolds utilizing components from mobile access and working towers specified in BS EN 1004 but in configurations that are outside of the scope of that standard.
These configurations include:
- Prefabricated tower scaffolds outside the height limits of BS EN 1004
- Towers with more than one working platform
- Large deck tower scaffolds
- Linked tower scaffolds
- Cantilever tower scaffolds
- Stepped tower scaffolds
- Tower scaffolds used as a means of access
- Towers built on base plates instead of castors
BS 1139-6:2014 applies to prefabricated tower scaffolds subject to windloads up to and including 0.1 kN/m2.
