What is a suspension scaffold?
Suspended scaffolds are platforms suspended by ropes, or other non-rigid means, from an overhead structure. Because two-point scaffolds are the most common type of suspended scaffold, this eTool uses the Two-Point module to describe requirements that apply to all suspended scaffolds.

"Float (ship) scaffolds." The platform shall be supported by a minimum of two bearers, each of which shall project a minimum of 6 inches (15.2 cm) beyond the platform on both sides. Each bearer shall be securely fastened to the platform. Rope connections shall be such that the platform cannot shift or slip.

Scaffolding Width
This type of scaffolding measures around 29 inches across. This allows it to be wheeled through standard-sized doorways, making it suitable for working inside buildings, for example, for maintenance or repairs inside a hospital or office building.
Scaffolding Length
Scaffolding is available in standard lengths of 6ft, 8ft, and 10ft. This provides enough variation that makes scaffolding able to be configured to a wide variety of sizes to suit the need of almost any construction project.
Extension Sets
Extension sets are available if you need to increase the size of your scaffolding. These come in standard lengths of 4ft, 5.5ft, and 6.9ft. Extension sets can be used on both single-width and double-width scaffolding as long as they have been securely constructed with proper bracing.
Scaffolding Board Sizes
Scaffolding boards are an important component of scaffolding. They need to be used with a scaffolding frame because they have been designed specifically for this use, and therefore are the perfect size to fit the framework.
Width
The width of the scaffold and the distance between the front and back rows of standards is determined by the intended use of the scaffold. This width should be a minimum of 600mm and is often expressed in terms of 'the number of boards wide'.
