What are the three types of scaffolds aerial?
There are three basic types of scaffolds: Supported scaffolds, which consist of one or more platforms supported by rigid, load-bearing members, such as poles, legs, frames, outriggers, etc. Suspended scaffolds, which are one or more platforms suspended by ropes or other nonrigid, overhead support.
What are five requirements for scaffolding?
safe working load / load class. maximum leg loads. maximum tie spacing both horizontal and vertical and tie duty. details of additional elements such as beamed bridges, fans, loading bays etc, which may be a standard configuration (see note 1 ref TG20:13) or specifically designed.
What is the strongest scaffolding?
Double Scaffolding This scaffolding type is generally stronger and provides better support for construction works as compared to brick layer’s (single) scaffolding. Double scaffolding differs from single scaffolding in that it features two rows of standards separated by ledgers for better support.
What are the 2 types of scaffolds?
There are 8 different types of scaffolding including:
- Single Scaffolding.
- Double Scaffolding.
- Aluminium Scaffolding.
- Steel Scaffolding.
- Kwikstage Scaffolding.
- Scaffold Towers.
- Cantilever Scaffolding.
- Trestle Scaffolding.
Can I erect my own scaffolding?
Because working at heights poses significant risks, both to those working on the scaffold and those below, we do not recommend that you attempt to erect a scaffold on your own, unless you are trained and competent in scaffold erection. The safety of lives is too important to make scaffolding a DIY project.
What is the minimum height for scaffolding?
In the general industry, the height requirement for scaffolding is 4 feet above a lower level. For construction work, the height requirement is 6 feet above a lower level. All workers 10 feet above a lower level must have fall protection.
How high can bamboo scaffolding go?
Because of these dangers, there are specific requirements for sourcing bamboo. A usable piece is three to five years old and air-dried indoors for at least three months. The preferred length is around 20 feet, not long considering some structures can reach up to 600 feet.
Why do they call it bakers scaffold?
Narrow frame scaffolds are also called Baker for Perry scaffolding. Because of their small size, portability and configuration options, they can be used in many different construction and work applications. They function the same as a platform ladder and they are safer and cost less.

What are the specifications for a form scaffold?
(g) “Form scaffolds and carpenters’ bracket scaffolds.” (1) Brackets shall consist of a triangular-shaped frame made of wood with a cross-section not less than 2 inches by 3 inches, or of 1 1/4 inch x 1 1/4 inch x 1/8 inch structural angle iron. (2) Bolts used to attach brackets to structures shall not be less than 5/8 inches in diameter.
How much weight can a scaffold platform support?
Note: Platform units used to make scaffold platforms intended for light-duty use shall be capable of supporting at least 25 pounds per square foot applied uniformly over the entire unit-span area, or a 250-pound point load placed on the unit at the center of the span, whichever load produces the greater shear force.
How big does a metal bracket scaffold need to be?
(6) Metal bracket scaffolds: Maximum intended load: 25 lb/ft. (2) Uprights: 2 x 4 inch Bearers: As designed. Braces: As designed. (7) Wood bracket scaffolds: Maximum intended load: 25 lb/ft. (2) Uprights: 2 x 4 in or 2 x 6 in Bearers: 2 x 6 in Maximum scaffold width: 3 ft 6 in Braces: 1 x 6 in
