Specific requirements are described below. Fall protection consists of either personal fall-arrest systems or guardrail systems and must be provided on any scaffold 10 feet or more above a lower level. The number one scaffold hazard is worker falls. Fabricated Frame Scaffold Fall Protection They are frequently used in one or two tiers by residential contractors, painters, etc., but their modular frames and braces can also be stacked several stories high for use on large-scale construction jobs. Scaffolding In Placeįabricated frame scaffolds are the most common type of scaffolding because they are versatile, economical, and easy to use. There are more modern scaffolding options these days. If you’re unsure which ones are best suited for your project, you can always consult established scaffolding contractors that offer both equipment and services.Fabricated frame scaffold: A scaffold consisting of platforms supported on fabricated end frames with integral posts, horizontal bearers, and intermediate members. So when you need a more lightweight system, suspended scaffolds are a more cost-effective choice.Įach type of scaffolding system has specific requirements when it comes to securely fastening them. Thus, some companies use them for building maintenance and window washing. This scaffolding type is best for high-rise applications that do not involve massive or heavy loads. Catenary: A platform is supported by vertical and parallel cables attached to a part of the building.Multi-level: A multi-level is simply a multi-point or a two-point suspension with two or more platforms or levels.Multi-point Adjustable: If a single-point is supported by one rope, the multi-point uses more than two ropes to carry the platform.It has similar use with two-point scaffolds. Single-point Adjustable: It consists of one rope tied to overhead support to hold one platform.It is typically used by window washers but is widely used in high-rise construction as well. Two-point Scaffold: The most common subtype of a suspended scaffold is the two-point, where ropes hang the platform from stirrups.The subtypes of suspended scaffolds include: They are also called “swing-stage” or “suspended cradle” and are typically used for medium-height buildings to skyscrapers. Unlike supported scaffolds, these types are tied to a structure and are often adjustable. Suspended scaffolds use non-rigid overhead support, such as metal or fibre ropes to carry one or more platforms. For example, a mobile scaffold can be assembled up to 12 meters, while most supported scaffolds follow a height-to-base ratio, as specified by the equipment manufacturer and Safe Work Australia. These types support significant loads in construction, from supporting workers to carrying building materials like masonry blocks. They can be built in multiple directions and are best used for heavier loads. From the name itself, this subtype consists of coupling devices that connect tubing members. They are commonly used in plastering, painting, and other finishing works where it is necessary to keep changing positions. Also known as manual or propelled, they are designed with wheels or casters to be able to move freely. They are versatile for a variety of projects and make an economical option. These are modular frames that can be stacked from two levels to several stories. The most common subtype of supported scaffolds. The subtypes of supported scaffolds include: If its foundation isn’t level, the whole assembly will be at risk. They are freestanding and need stable footing. Supported scaffolds consist of firm, load-bearing parts (legs, poles, frames, brackets, outriggers) and their accessories to support one or more platforms. Thus, scaffolds can be either supported or suspended. Usually, they use scaffolds to reach high walls and roofs, but they can use them for large excavations, as well. Scaffolds are temporary platforms that are used by workers to access different heights. Generally, scaffolds can be categorized into two basic types and subsequently classified into several subtypes each. Since a scaffold is always essential in most construction projects, you only need to decide on the type that best serves your project needs. As nonpermanent structures, they can take specific configurations depending on what a project requires, i.e., a good foundation, the maximum load, hazards to avoid, how wide or narrow your space is, and many other factors. There are different types of scaffolds for a variety of purposes.
