12/27/2023 0 Comments Types of suspended scaffoldingCounterweights can not be made of flowable materials such as sand, gravel, and similar materials that can shift, move, or easily be dislocated. Never use masonry units, rolls of roofing felt, and other similar construction materials as counterweights. Only items specifically designed as counterweights may be used to counterweight scaffold systems. Counterweights must be secured by mechanical means to the outrigger beams to prevent accidental displacement. Suspended scaffold outrigger beams must be stabilized to the supporting surface using counterweights or bolts or direct connections to the floor or deck. OSHA Standard 1926.451(a)(4) Each suspension rope, including connecting hardware, used on adjustable suspension scaffolds shall be capable of supporting, without failure, at least 6 times the maximum intended load applied or transmitted to that rope with the scaffold operating at either the rated load of the hoist, or 2 (minimum) times the stall load of the hoist, whichever is greater. Suspension ropes, including connecting hardware, used on suspension scaffolds must be capable of supporting at least 6 times the maximum intended load applied. All components used as part of the scaffold must also be able to support the workers and scaffold itself. Suspension scaffold outrigger beams, cornice hooks, parapet clamps, and similar devices, must rest on surfaces capable of supporting at least 4 times the load imposed on them by the scaffold, operating at the rated load of the hoist. Workers must ensure that the surface or roof they use to anchor to is strong enough to support the suspended scaffold. The anchorage is critical because it holds the weight of the workers, their tools, and supplies as well as the entire platform, the cables, and the hoists being used to operate the suspended scaffold. The first step to ensuring worker safety when using suspended scaffolds is to start with a sound and secure anchorage system. In addition, workers must be trained and familiar with the precautions and manufacturer’s operating procedures for the specific model and brand of scaffolding systems they are using at their site. Most suspended scaffolds must meet basic OSHA regulatory requirements however, it is always important to follow the regulations for the specific type of suspended scaffold. ![]() These types of scaffolds are usually hung by rope or cables connected to stirrups at each end of a platform and allow the workers to be raised and lowered to reach various work locations. ![]() For especially difficult areas the safest approach may be to use a suspended scaffold.Īccording to OSHA, two-point adjustable suspension scaffolds, also known as swing-stage scaffolds, are perhaps the most common type of suspended scaffold. Using scaffolds to access hard-to-reach areas is often necessary for many construction activities. Working at height is always dangerous which makes it extremely important to provide a safe way for workers to access their job location.
