Unlike all other types of suspended scaffolding, if the ladders are long enough, multiple platforms can rest on them to create multiple layers. A platform runs between the two ladders, resting on the rungs. Multilevel scaffolding is suspended from the structure by ropes or wires, each of which supports a ladder that faces perpendicular to the structure. When you see scaffolding hanging on the side of skyscrapers, this is usually two-point (swing stage) scaffolding. The most common type of suspended scaffolding, two-point (swing stage) scaffolding consists of a platform supported at either end by ropes or wires, which can be moved up and down. Interior hung scaffolding is exactly like float scaffolding, but the ropes or wires hang from two parallel support beams running parallel to the structure instead of one. It is also referred to as ship scaffolding. Like catenary scaffolding, float scaffolding is not mobile. The ropes or wires support the two ledgers that support the platform. Float Scaffoldingįixed-length ropes or wires hanging from a support beam running parallel to the structure. A platform rests on the horizontal ropes or wires.Ĭatenary scaffolding is not mobile, so it can’t be adjusted to a different height or easily moved to reach a new area. These vertical wires or ropes connect to two ropes or wires running horizontally and parallel to the structure. In catenary scaffolding, ropes or wires hang from a structure above. Suspended scaffolding can also be dangerous to use in high winds, as a swaying platform can snap the support lines. However, weight limits are a concern and horizontal reach may be limited. Suspended scaffolding is preferred for reaching the tops of tall buildings, for which supported scaffolding may be too expensive and time-consuming to construct. Suspended scaffolding consists of platforms that are suspended from above, usually a rooftop, by non-rigid materials like ropes or wires.

We’ve compiled a list of the most common types, plus two alternatives and safety tips below. A double frame means the scaffolding is independent from the structure itself. A single frame means there is only one frame supporting one side of the scaffolding with the structure itself acting as another support. Scaffolding can either be a single frame or a double frame. Scaffolding made entirely from wood materials is referred to as wood pole scaffolding. Even though it is more expensive, steel is the preferred material for scaffolding because of its durability and safety. There are 17 different types of scaffolding made from different materials, but the most common materials are wood and steel. Scaffolding is a temporary elevated structure designed to support workers and materials as they work, usually alongside a structure like a building.
