(2) Side bracket. A side bracket (Figure 4-18) is damped on the scaffold uprights to provide
platforms at various height levels.

(3) Rolling tower. Use a rolling tower if the scaffold will be subjected to frequent moves;
however, use a rolling tower only on solid floors. To construct a rolling tower, replace the scaffold
footing plates with locking casters. For safe operation, the tower's height must not exceed four times its
smallest base dimension; in addition, the tower must have a guardrail above the working platform.
c. Swing-stage scaffold. A swing-stage scaffold (Figure 4-19) is used to reach the upper
surfaces of an exterior wall, and it is suspended from the building's roof or cornice with ropes or steel
cables. The scaffold consists of the following parts: two block-and-tackle sets, two cornice hooks, two
swing stirrups, a guardrail, and a platform.
