Most of us have seen supported scaffolds in use, as these are commonly utilized by the construction industry to reach very high work areas and beyond the reach of construction workers standing at ground level. Thus, specialized equipment such as aerial lifts and scissor lifts are now considered to be types of supported scaffolds. Modern times have revolutionized and added to the types of supported scaffolds. However, when designed and built, it important to ensure the structural supports are braced to avoid tilting, wobbling, or other movements. These types of scaffolds can hold substantial weight. Supported Scaffolds – these are platforms that are built with strong rigid ground supports such as brackets, poles, posts, legs, frames, outriggers, etc.Suspended Scaffolds – these are platforms that are hung from a permanent solid structure such as a roof and are supported by the use of strong rope, wire, or other similar flexible materials.There are two major categories of scaffolds as explained below.

Scaffolds are temporary structures built to help reach work areas that are well above ground level.
