Birdcage scaffold

A birdcage scaffold is an independent scaffold that consists of more than two rows of standards in both directions and is connected by ledgers and transoms. It is mainly used for work that is to be carried out on a single level, such as ceilings.

Single pole scaffold

This section only applies to wooden single-pole scaffolds (see Figure 23.15). This type of scaffold has platforms resting on putlogs or cross beams, the outside ends of which are supported on ledgers secured to a single row of posts or uprights, the inner ends of which are supported on or in a wall. The advantage of a Single pole Scaffold is that less materials are used as there are no inside standards or ledgers. The disadvantage is that if the ground dries out and shrinks slightly, or a heavy load is placed on the scaffold then as the standards and ledgers drop they lever the brickwork apart!
