They are designed with security features such as guardrails and toeboards to reduce the risk of fall accidents. They offer safer access than traditional scaffolding structures.
7. Space-Saving
One of the significant benefits of suspended scaffolding is that it is a space-saving temporary structure. Swing stage scaffolds take less ground space, which proves quite useful in crowded urban areas projects. They allow construction managers to keep the ground clear as there is no large scaffolding base they need to install. As a result, there is minimal disruption at the ground, while workers still enjoy a great deal of accessibility to construction or maintenance sites.
What are Disadvantages of Suspended Scaffolding?
The eight disadvantages of suspended scaffolding are as follows:
- Limited to High-Rise Buildings
- Not Suitable for Heavy Construction
- Low Surface Coverage
- High Loading Restrictions
- Complex Setup
- Weather Sensitivity
- Wind Sensitivity
- Higher Setup Costs
1. Limited to High-Rise Buildings
The biggest drawback of suspended scaffolds is their unsuitability for low-rise buildings. They are designed for only high-rise buildings and tall structures where you need to anchor the structure from above. They can’t be used for projects that don’t have significant heights. Therefore, they are helpful only for urban settings and high-rise projects and unsuitable for other construction projects.
2. Not Suitable for Heavy Construction: Suspended scaffolds have limited load capacity and must be more suitable for heavy-load construction. You can’t use a scaffold when a project requires extensive facade renovations requiring heavy cladding material. They can bear loads of large-scale masonry.
3. Low Surface Coverage: Another disadvantage of suspended scaffolding is its low surface coverage. Conversely, workers can access wide and tall areas with traditional scaffolding. It is time-consuming for workers to reposition the scaffold to access other exterior areas of the building, and this adjustment works efficiently.
4. High Loading Restrictions: Workers must adhere to load limits with suspended scaffolding. This structure’s structure is its high loading restriction. Careful planning is required regarding load weights because exceeding the limit will lead to security risks. Workers should constantly monitor the weight limit to prevent unfortunate incidents.
5. Complex Setup: The setup of a suspended load is complex and requires skilled personnel. An expert installer needs to secure the anchor balance to ensure that the suspended scaffold is installed properly. Any error or mistake during the setup process will increase significant security risks.
6. Weather Sensitivity Another disadvantage of suspended scaffolding is that it remains highly vulnerable to extreme weather conditions such as rain, snow, heavy wind, etc. Harsh weather can create dangerous work scenarios for workers as tools or materials can fall from the height, causing the platform to sway.
7. Wind Sensitivity Another drawback of suspended scaffolding is that it is highly wind-sensitive. This structure hangs from above, and moderate winds can induce swinging and pose serious safety risks. Workers need help continuing to do their regular tasks during heavy wind scenarios.
8. Higher Setup Costs The Overall setup cost of a suspended scaffold is high. Many factors contribute to this high cost. First, it needs specialized equipment and skilled labour. Once the setup is done, rigorous checks need to be performed to ensure that the complete setup is safe for workers’ use.
What are the uses of Suspended Scaffolding?
The ten uses of suspended scaffolding are as follows:
- Building Facades
- Window Installation and Cleaning
- Bridge Maintenance
- Industrial Maintenance
- Tower and Wind Turbine Maintenance
- Ship Maintenance
- Heritage Building Restoration
- Ceiling Renovations
- Billboard Installation
- Exterior Cleaning Tasks.
1. Building Facade
Suspended scaffolding is mainly used to inspect, maintain and clean building faces. The facade accumulates dirt and pollution over time, and workers access the exterior of the building through this temporary structure and perform cleaning tasks across the entire height and width of the building using tools like pressure washers, scrapers, and chemical cleaners. Inspectors use suspended structures to inspect the building’s exterior and check the facade for any wear, tear, or potential damage. Maintenance tasks such as minor repair, repointing mortar joints, sealing cracks, etc, are done at various heights using a suspended scaffold.
2. Window Installation and Cleaning
Another common use of suspended scaffolding is window installation and cleaning. Workers use a swing stage to fit the window frame in the facade structure. They install the windows and ensure that they are sealed properly. They are also used to clean windows of high-rise structures. This cleaning is crucial for maintaining the building’s aesthetic value, and cleaners rely on suspended scaffolding to perform tasks with ease and speed.
3. Bridge Maintenance
Suspended scaffolding is also used in the bridge maintenance process. Inspectors use a swing stage to inspect the bridge’s facade for wear, tear, or damage. Later, they hire workers who can address the damages caused by environmental exposure. Workers perform painting, minor repairs, or sealing bridge facades. This regular maintenance increases the lifespan of bridges and boosts infrastructure safety.
4. Industrial Maintenance
Another use of suspended scaffolding is in industrial maintenance tasks. Workers use swing space during surface cleaning, structural element repair, and maintenance of industrial ventilation systems.
5. Tower and Wind Turbine Maintenance
Suspended scaffolding is also used to maintain the external surfaces of towers and wind turbines. Workers use a scaffold platform to complete tasks such as painting, composite material repair, and bolt tightening.
6. Ship Maintenance
Suspended scaffolds are also useful in various ship maintenance tasks. Workers perform regular inspections and address issues like corrosion and other damages. They also prove useful during the application of protective coatings on the ship’s facade and cleaning its exterior to maintain its aesthetic appeal.
7. Heritage Building Restoration
Suspended scaffolding proves quite useful in heritage building restoration. Renovations of historic buildings are sensitive as workers need to clean, repair, or replace the facade elements without compromising the architectural integrity of the structure. They need to match the material with the original as closely as possible, and this task can be done with precision and without damaging ground level with a suspended platform.
8. Ceiling Renovations
Suspended scaffolds are used during ceiling renovation and remodelling tasks in tall structures. Workers stand on the swing stage and install acoustic panels, decorative elements, and other things on the walls, interiors, and ceilings.
9. Billboard Installation
Suspended scaffolds are also used during the billboard installation process.
10. Exterior Cleaning Tasks
Suspended scaffolds are also useful in cleaning entire facades. Over time, dirt, grime, pollutant deposits, and biological growth on the facade lead to material degradation. Workers deep clean the facade to prevent degradation and keep the area sparkling.
What are the parts of Suspended Scaffolding?
The twelve parts of suspended scaffolding are as follows:
- Platform
- Support Cables
- Stirrups
- Hoist
- Guardrails and Toeboards
- Counterweights
- Safety Harness and Lanyards
- Outriggers
- Tie Backs
- Electric Motors
- Pulleys
- Anchors
1.Platform
The platform is the most crucial part of the suspended scaffold system. Workers stand in this main work area and do their regular tasks. The platform is made from durable and lightweight materials. The exact size of the platform depends on the project requirement, but it should be strong enough to hold the weight of tools, materials, and workers.
2.Support Cables
Support cables are high-tensile strength steel cables used to suspend the scaffold platform from the overhead structure. They maintain scaffold stability and safety. Inspectors need to inspect these cables regularly so issues like wear, corrosion, and damage can be fixed on time.
3.Stirrups
Stirrups are U-shaped brackets that connect support cables to scaffold platforms. They allow easy platform height adjustment and play an important role in the overall levelling and stability of the swing stage.
4.Hoist
A hoist is a device used to raise or lower the scaffold platform. It can be operated manually or through electricity. The hoist mechanism comprises gears, brakes, and other parts and ensures smooth platform movement.
5.Guardrails and Toeboards
Guardrails are safety rails installed at the edge of the platform. These safety measures prevent workers from accidentally stepping out of the platform. Toeboards are raised edges around the bottom of the platform. These boards ensure that tools and materials don’t fall from the platform or cause damage or injuries on the ground.
6.Counterweights
Counterweights are weights placed on the opposite side of the rigging system. They balance the load of the scaffold and ensure the stability of a non-anchored suspended system.
7.Safety Harness and Lanyards
The safety harness is a full-body harness that workers wear. This harness distributes the force of a fall across the body and protects the workers by keeping them upright. It prevents them from hitting the ground. The lanyard connects the harness to an anchor point and reduces the risk of injury by arresting a fall. Safety harnesses and lanyards are essential to the personal fall arrest system. The primary purpose of these components is to ensure that workers can be caught safely if a fall occurs.
8.Outriggers
Outriggers are beams that extend horizontally from the building. They distribute the weight of the scaffold away from the building’s edge. They often bear the counterweight and support the load of scaffolding.
9.Tie Backs
Tiebacks are ropes or cables that tie scaffolds to a sturdy part of the building. They are used to secure the scaffold to the building. These additional safety features of the scaffold increase the stability and security of the swing stage and prevent it from swaying.
10.Electric Motors
Electrical motors power the hoist to raise or lower the scaffolding platform. These motors should be strong enough to hold the load. Another essential feature of electric motors is their durability; they must withstand various construction environments,
11.Pulleys
Pulleys are the mechanical system of a suspended scaffold. They let the hoist function properly by guiding the support cables. They also allow smooth raising and lowering of the platform.
12.Anchors
Anchors are fixed points on the building to which the scaffolding system is secured. They should be firm and rough to hold the weight of the scaffold and the dynamic load usually applied to them during scaffolding use.
