The rolling tower, or ___ scaffold, is widely used for small jobs, generally not more than 20 feet in height.

• A. Stationary
• B. Flexible
• C. Mobile
• D. Adjustable

Answer: (C)

Mobility is what defines a rolling tower. A mobile scaffold is built with wheels so you can roll it from one spot to another, which is ideal for small jobs where you don’t need a tall, fixed setup. These towers are commonly used for work up to about 20 feet high because their design prioritizes portability and quick repositioning over maximal height. A stationary scaffold stays in one place once set up, so it isn’t moved around the job site; flexible isn’t a standard scaffold category; adjustable refers to height changes but doesn’t capture the essential feature of moving the unit around. For short jobs, the mobile scaffold best describes the rolling tower.
