Suspension Scaffold, Lifts, and Hoists
A suspension scaffold contains one or more platforms suspended by ropes or other non-rigid means from an overhead structure, such as the following scaffolds: single-point, multipoint, multi-level, two-point, adjustable, boatswains' chair, catenary, chimney hoist, continuous run, elevator false car, go-devils, interior hung, masons', and stone setters'. We will discuss eight of the general types of suspension scaffolds, lifts, and hoists. 1926.450(b)
Single-Point Adjustable
A single-point adjustable scaffold consists of a platform suspended by one rope from an overhead support and equipped with means to allow movement of the platform to desired work levels. The most common among these is the scaffold used by window washers to clean the outside of a skyscraper (also known as a boatswain's chair). More information on this scaffold.
Two-Point Swing Stage
The two-point adjustable suspension scaffold, also known as a swing-stage scaffold, is perhaps the most common type of suspended scaffold. Hung by ropes or cables connected to stirrups at each end of the platform, it is typically used by window washers on skyscrapers, but plays a prominent role in high-rise construction as well.
