What are the three basic types of scaffolds?

The three basic types of scaffolds primarily acknowledged in construction and pipe fitting contexts are single, sectional metal-framed, and suspension. Each type serves distinct purposes and is designed to provide support at various heights and environments.

Single scaffolds are typically used for working on walls, providing a stable approach to both large and small-scale projects. These scaffolds consist of vertical and horizontal frames that are attached together to create a stable working platform.

Sectional metal-framed scaffolds are modular in design, allowing for ease of assembly and disassembly on-site. This type is particularly beneficial in tasks that require adaptability to different heights and configurations, enhancing a worker's access to elevated areas.

Suspension scaffolds are designed to be suspended from overhead structures, offering significant versatility in areas with limited building surfaces. They are particularly advantageous for tasks that involve facade work or other situations where a secure base cannot be established.

While other options mention different configurations and types, they do not encompass the foundational classifications that are universally recognized in the construction field. Understanding these scaffold types is essential for ensuring safety, efficiency, and compliance with regulations during pipe fitting and construction tasks.
