Which of the following are the three main types of scaffolding?

• A. Fixed, adjustable, and flexible scaffolds
• B. Supported, suspended, and rolling scaffolds
• C. Mobile, static, and temporary scaffolds
• D. Permanent, temporary, and composite scaffolds

Answer: (B)

The three main types of scaffolding are indeed supported, suspended, and rolling scaffolds. Supported scaffolding is the most common type and is constructed using a platform that is supported by a framework, which is anchored to the ground or building. This type is often used for construction and repair work where stability and strength are priorities. Suspended scaffolding is typically used when the work needs to be done on taller structures where the scaffold must be hoisted vertically. This type involves platforms that are suspended from a building or structure, allowing workers to reach high areas more safely and efficiently. Rolling scaffolds, as the name suggests, are on wheels, making them very portable. This type is especially useful for projects that require frequent relocation to different spots at a work site. The mobility aspect allows workers to save time and effort when moving their working platform. While other options include different configurations or types of scaffolding, "supported, suspended, and rolling scaffolds" accurately represent the primary categories recognized in standard scaffolding practices, making it the correct answer in this context.
