Cantilever scaffold, also known as jib or trussed scaffold, is most commonly used at the tops of buildings, as well in tight corners and other hard to reach areas. The cantilever scaffold is formed with tubes cantilevered out of an opening in the building, perhaps a window. This is done when one does not want to obstruct the space below, which could perhaps be a busy street. One edge is attached to the building while the other is left exposed.
Boards and poles projecting out of the building should be held in place by a tie bolt, which is drilled through the floor slab to ensure stability and security. Every single “floor” built should also be secured to the building with bots. People working on cantilever scaffolding are often required to wear harnesses as a safety measure.
