Types of Supported Scaffolds (Straight Run, Large Area/Dance Floor, Birdcage, Stair Tower)

There are a number of types of supported scaffolds, including the following:

  • Coupler and tube
  • Specialty
  • Pump jack
  • Wood pole or pole
  • Propelled or manually mobile
  • Mast climbers
  • Ladder jack
  • Fabricated frame or frame scaffold, and more

Specifically, in the following paragraphs, straight run, large area/dance floor, birdcage, and stair tower scaffolding will be examined.

Straight Run Scaffolding

Running scaffolding refers to scaffolding that it is comprised of two or more bays as a double pole scaffold.

You may also hear straight run scaffolding referred to as run scaffolding, running scaffolding, straight scaffolding, etc. For straight run scaffolds, longitude bracing across the outer and inner rows of posts is diagonally installed in both directions. From the base of the end posts, it extends upward to the top of the scaffolding at an angle of roughly 45°. If scaffolds are longer than they are high, from the base of the end posts, bracing is installed upward to the opposite end posts. From there, until it reaches the top of the scaffold, it’s placed in alternating directions. Bracing is installed:

  • As close as possible to the intersection of the runner and post, or…
  • As close as possible to the intersection of the bearer and post

Large Area/Dance Floor Scaffolding

When you need scaffolding for a large area or a dance floor, a specific type of scaffolding can/should be used. This is a scaffolding system that, at a consistent elevation, features a very large platform. This is opposed to a vertically ascending series of smaller platforms. Typically, this type of scaffolding makes it easier and safer to work on or perform on structures of a larger stature, but with a consistent height. The entire scaffolding system is on a platform that’s elevated. For work on uneven ground, this adjustable structure provides a level platform for work, dancing, stages, etc.

Birdcage Scaffolding

In structures where high-level access is required, this independent birdcage scaffold may be used. Examples:

  • To access fire alarms and/or sprinklers
  • To work on ventilation systems
  • Fitting lights into ceilings and more

 This type of scaffolding consists of two or more rows of standards connected by ledger beams. These run in both directions and are connected at every lift height. Another name for birdcage scaffolding is “independent scaffold”. Frequently, the erection and design of these scaffolds is irreplacable when elevation is an important aspect of the work being done.

Stair Tower Scaffolding

When people need to reach a certain height, stair tower scaffolding is a common method used to work at that point. It is critical that these systems always be used correctly, assembled properly, and well maintained.

Examples where stair tower scaffolding might be used:

  • Access certain building entry points
  • Work on valves in an industrial application
  • Access a scaffold platform and more

Tower scaffolding, on the other hand, is used to prevent those working at significant heights from falling. Once again, only competent, trained teams should assemble and disassemble this type of scaffolding. It’s also important that it be appropriate for the type of work being done.

Scaffold towers can include the following:

  • GRP (fiberglass) scaffold tower
  • Standard scaffold tower
  • One man tower
  • AGR (advanced guard rail scaffold) tower
  • Cantilever tower
  • Staircase (as described above)
