In proprietary scaffolds, the main building elements are designed so as to fit snuggly and are more modular. Not all scaffolding depends on tubing and piping. Because they are attached to the overhead device via ropes, they can be lowered or raised. Like slung scaffolds, suspended scaffolds hang from an overhead structure or device, but possess a great range of mobility. They cannot be moved side to side, raised higher, or lowered. Slung scaffolds hang down from an overhead structure or device, but are relatively resistant to being otherwise moved.

Often, free-standing scaffolds resemble two towers that can be moved and resituated as needed. This type of specialized scaffold is designed to stand on its own, without attaching to another structure for stability. As a result, the entire scaffold is independent of the building, but is tied to the building for security. What is independent scaffolding? The difference between putlog and independent scaffolding is that, unlike putlog scaffolds, independent tied scaffolds rely on two lines of standards to support the working deck, not the building’s wall. Putlog scaffolds can only be used on walls with adequate strength to support the weight of the scaffold and the putlog itself. In order to use the wall as support, a putlog, a transom with a flattened end that enables it to rest solidly on the edge of a wall, is used to attach the scaffold to the wall. Putlog scaffolds use the wall of the building being built as a support, in conjunction with standards to uphold the outer scaffold deck. (For a detailed explanation of these terms, please visit the article Basic Scaffolding Elements.) Putlog Scaffolds All of the following scaffolds discussed are of comprised of tubes and piping, meaning they rely on standards, transoms, and ledgers as their primary support network. We have listed below there various types of scaffolding in use today, included in this list are:Īccess scaffolds, which are designed for worker use and access, have several subcategories, such as putlog scaffolds and tied independent scaffolds, as well as several specialized variants. Other scaffolding systems, such as proprietary scaffolding, depend on more modular building elements. Some scaffolds are designed to work with basic tubes and piping.

Additionally, scaffolds also serve as a means of support for the building, helping worked-upon building areas remain stable and safe. Different types of scaffolding are used as an essential part of creating a safe environment during building construction and repair, as one of the main purposes of scaffolding is to provide a sturdy platform from which workers can access the building under construction.
