Suspended scaffold is used give support and access to working areas such as construction sites, industrial plants, and large structured buildings. The suspended scaffolds are installed on high-rise buildings, with the support of cable pulleys, for purposes like window washing, repainting buildings and bridges, repairing broken structures and much more.
Due to their baseless hanging structure, these suspended scaffoldings require unique safety measures.
Types of Suspended Scaffolds
Before understanding the safety measures of suspended scaffold, it is important identify the types of scaffolding.
#1 Double -Rope – Scaffolds supported with double suspension ropes is known as Double-Rope scaffolds.
#2 Boatswain’s Chair – A scaffolding with seating arrangement for a single person is termed as Boatswain’s Chair.
#3 Swing Stages – Framework supported by single rope suspensions, which are mostly used for light works is known as Swing Stages.
#4 Work Cages – Small racks or cradles hanging with a support of one suspension rope is a Work Cage.
#5 False Cars – One of the most specialised types of suspended scaffold, False Cars are mostly used for lift constructions.
How to control risk factors associated to suspended scaffolds?
Here are some the basic safety measures you need to follow while working with a suspended scaffold:
#1 Thoroughly investigate the mechanical linkages between the system parts.
#2 Based on the outboard and inboard projections, the counterweight should always be triple the highest rope tension of the support line.
#3 Design of the needles or suspension rigs should be verified by an expert to support the highest cable tension in the outboard.
#4 To prevent unwanted detachment of counterweights, they should be attached properly to the suspension rigs.
#5 Before installation, it is vital to double check the authenticity of winch ropes and other such materials.
#6 For your suspended scaffolding installations, you should only trust an Advanced Rigging or Advanced Scaffolding certified individual.
#7 Do not forget to check the ratings of the suspended scaffold. A reliable scaffold is marked with SWL (rated capacity).
#8 After you complete the installation, you should regularly do a maintenance check for the pulleys, cables, rooftop fastening, framework support and couplers.
#9 While working on a suspended scaffold you should never enforce any natural motion to the cradle or overload it. It can induce pendular movement and cause an accident.
#10 With suspended scaffoldings, it is crucial to check adequate power supply to the structure and flexibility of cables.
#11 Although prevention is better than cure; you should always be prepared for unwanted situations like an accident or natural calamity. There should be a properly planned emergency rescue process to bring out the trapped workers safely.
Safety Training Transitioning
Although the suspended structure of scaffolding looks different to the primary erected scaffold, certain similarities need to be considered. Just like the standard ground scaffold, you should check the stability of the systems like the locked castors, rooftop anchoring structures and the outriggers. Also, the placed counterweights should be well balanced with the daily load consideration.
