A needle beam is associated with which type of scaffold?

• A. An outrigger scaffold
• B. Suspended scaffold
• C. Rolling scaffold
• D. Stair Scaffold

Answer: (A)

A needle beam is used with outrigger scaffolds because it provides a through-the-wall support that ties the scaffold system to the building, allowing outriggers to project outward while the load is transferred back into the structure. This keeps the scaffold stable and prevents tipping when working away from the facade or where ground space is limited. Suspended, rolling, and stair scaffolds rely on different support methods (overhead suspension, wheels, or stair attachment) and do not use needle beams.
