What is the classification of scaffolds that supports over 75 pounds/square foot?

The classification of scaffolds that supports over 75 pounds per square foot is categorized as special duty. This classification is used for scaffolds designed for specific applications where heavy loads are expected. When the load capacity exceeds the standard requirements for medium duty or heavy duty, which typically accommodate lighter weights, special duty scaffolds are employed to ensure safety and efficiency in construction projects.

Light duty scaffolds are intended for lighter loads, such as maintenance work, while medium duty scaffolds support more weight but are still under the threshold that necessitates special considerations. Heavy duty scaffolds can handle substantial loads but still fall short of the unique specifications required for special duty applications. Thus, special duty scaffolds are specifically designed to meet the demands of heavier operational loads, which is crucial in many construction environments where durability and reliability are essential.
