What type of scaffolding is supported by two essentially horizontal and parallel ropes?

1. Fixed scaffold

2. Floating scaffold

3. Suspension scaffold

4. Scissor scaffold

The correct answer is: Suspension scaffold

Suspension scaffolds are characterized by their support system, which relies on two horizontal and parallel ropes. This design allows workers to operate from a platform that can be suspended over a specific area, particularly useful for tasks on high-rise constructions where traditional scaffolding might be impractical or impossible to set up. The ropes enable the scaffold to be adjusted in height, providing flexibility and access to various levels of a building or structure. In the context of construction and maintenance, the suspension scaffold is particularly advantageous for projects requiring work on façades or ceilings, as it can be easily maneuvered into position. This type of scaffold is designed to hold the weight of workers and their tools safely, making it a reliable option when working at heights. The other types of scaffolding mentioned do not share this same support mechanism. Fixed scaffolding is stationary and relies on a more permanent structure. Floating scaffolding is employed on water and is not supported by horizontal ropes. Scissor scaffolding features crisscrossed supports and is typically used for interior applications where a sturdy platform is needed to reach elevated areas. Each type serves different purposes based on the specific construction needs.
