Setting up Ringlock Modular scaffolding requires careful planning and adherence to safety guidelines. While specific regulations and guidelines may vary by location, there are some general rules that are commonly followed. Keep in mind that these are general guidelines, and it’s crucial to consult local regulations and seek professional advice for your specific situation. Here are some primary rules for setting up Ringlock Modular scaffolding up to 5 meters in height:
- Foundation and Ground Conditions:
- Ensure that the ground is stable, level, and capable of supporting the weight of the scaffold and its intended load.
- Use larger or longer sole boards to distribute weight across a further distance on softer grounds.
- Use appropriate base plates or adjustable base jacks to distribute the load evenly and provide stability.
- When building scaffolding onto Deckings or Roofs, or any cantilevered or load baring platform then you need to use Shoring props under the platforms to support the weight of the load.
- Scaffold Components:
- Use only components provided by the manufacturer of the scaffolding system.
- Ensure that all components are in good condition, free from defects, and suitable for the intended use.
- Assembly and Disassembly:
- Follow the best practice assembly and disassembly instructions precisely.
- familiarise yourself with the Scaffolding best practice guidelines in New Zealand, WKS-5-scaffolding-in-New-Zealand
- Do not attempt to modify or alter components unless approved by the manufacturer.
- Bracing and Ties:
- Install diagonal and horizontal bracing to ensure the stability of the scaffold.
- Bracing must be applied every 4th bay or no more then 4 bays without braces before needing to apply.
- Braces must be applied every 2m in height on applicable bays.
- At least one of the scaffolding width ends should be braced also.
- Use appropriate ties or wall anchors to secure the scaffold to the structure it is leaning against, ensuring it is stable and resistant to movement.
- Alternatively use outriggers or rakers to prevent scaffolding from tipping over.
- Rules for needing outriggers, 3 x the width in height of the deck level and above needs outriggers or 3 x the least base width. For example .73m wide scaffolding needs outriggers at 2.1m deck height and above, with a width rule for the outriggers and scaffolding of 1/3 of the scaffolding platform height.
- Platform Construction:
- Guardrails and Toe boards:
- Install guardrails and toe boards on all working platforms, especially those located at height.
- Guard rails must be installed at 500mm high and 1m high.
- Use guard rails, When the scaffolding is further then 300mm from the building or there is a gap of 300mm or larger between the scaffolding and the wall.
- Ensure guardrails are at the appropriate height and meet local safety standards.
- Toe boards must be a minimum of 150mm in height. You can make your own or use wood, but it must be secured.
- Access and Egress:
- Provide safe and secure access to all working platforms using ladders, staircases, or other approved means.
- Ladders must not exceed 4.2m in height between working levels including the ground.
- We strongly recommend using internal ladder decks in-between deck levels.
- Ensure that access points are properly secured and equipped with guardrails.
- Load Capacity:
- Adhere to load capacity limits specified by the manufacturer.
- Consider the combined weight of workers, tools, and materials when calculating the load on the scaffold.
- Light duty scaffolding = 225kg per bay
- medium duty scaffolding = 450kg per bay
- Heavy duty scaffolding = 675kg per bay
- Although our scaffolding is tested to a heavy duty loading, it is generally considered to be constructed for a light duty purposes in the residential sector.
- Regularly inspect the scaffold before each use and after any alterations or adverse weather conditions.
- Only allow trained and authorised personnel to inspect, erect, alter, or dismantle the scaffold.
- Fall Protection:
- Implement fall protection measures, such as personal fall arrest systems, where there is a risk of falling from a height.
- When the deck level height of the scaffolding is within 1m of the roof edge or gutter edge, then roof edge protection rails can be applied to the outside of the scaffolding.
- When the deck level height of the scaffolding is further then 1m below the edge of the roof or gutter, Roof edge protection must be applied along the roof edge. There must be no more then 200mm of gap between the roof and the edge protection railing, 100mm is suggested.
- Edge protection railing must extend at least 1m up from the roof edge at intervals of 500mm and 1m including railing in line with the roof edge pitch going down.
- Ensure that workers involved in the assembly, disassembly, and use of the scaffold are properly trained and familiar with safety procedures.
Always consult with a qualified scaffolding professional or engineer to ensure compliance with local regulations and to address site-specific considerations. Safety should be the top priority when working with scaffolding at any height.
Assembly Sequence for Ringlock modular scaffolding.
Please check our Use Instructions page for some of our set-up instructions on mobile towers. More can be found on the individual package pages of the mobile scaffold category.
The assembly sequence for Ringlock modular scaffolding around a standard 2-story house typically involves several steps to ensure safety, stability, and efficient construction. Keep in mind that the specific steps may vary depending on the design of the scaffolding system and the requirements of the particular job site. Here is a general assembly sequence:
- Safety Check:
- Site Preparation:
- Clear the work area around the house to create enough space for assembling and erecting the scaffolding.
- Check the ground for stability and make any necessary preparations, such as leveling the ground.
- Base Assembly:
- Ledgers & U Transoms:
- Install ledgers between the vertical standards at base level both width and length. This provides Stability to the structure.
- Install U Transoms between the vertical standards at the deck level. This provides a cavity for the decks to go into.
- Ensure that the ledgers & U Transoms are securely connected to the standards.
- Hammer in the pins, with force.
- Build Upwards:
- Platform Installation:
- Guardrails and Toe Boards:
- Continue Building Up:
- Final Inspection:
- Conduct a final inspection to ensure that all components are properly assembled and secured.
- Make sure the scaffolding is plumb, level, and stable.
- When the work is complete, follow a systematic dismantling process in the reverse order of assembly.
- Ensure that all workers are clear of the scaffolding before dismantling any components.
Always follow the best practice guidelines and safety regulations when assembling and erecting scaffolding. Additionally, it’s essential to have a competent person oversee the assembly process and conduct regular inspections to ensure ongoing safety and stability.
Falling from heights, best practice summary
Below is an excerpt taken from the
Around scaffolding and roof edge protection. We recommended a thorough read of the document as it is very informative when working at heights in NZ.
Scaffolds are a common way to provide a safe work platform. There are a wide variety of scaffolding systems available.
All scaffolds should comply with the Scaffolding, Access & Rigging New Zealand, Scaffolding Best Practice Guidelines for Scaffolding in New Zealand or equivalent guidelines or a higher standard.
All scaffolds should be erected, altered and dismantled by persons who have been trained and have suitable experience with the type of scaffolding being used.
All scaffolds from which a person or object could fall more than five metres, as well as all suspended scaffolds, should be erected, altered and dismantled by or under the direct supervision of a person with an appropriate Certificate of Competency. This work must be notified to the Ministry of Business, Innovation and Employment as particularly hazardous work. A scaffold register should be kept on site as a record of regular inspection. More information about Notification of Particular Hazardous Work can be found in section 8.6.
All scaffolds shall be supplied with adequate information for the scaffold user, such as a scaffold tag or handover certificate. The information supplied shall include:
- › its intended use
- › safe working load
- › dates of inspections (as applicable—the scaffold provider can advise the frequency of these dates)
- › manufacturer’s instructions for assembly
- › any special conditions and limitations.If a scaffold has been altered, modified, tampered with and/or appears to be unsafe, the scaffold shall not be used until it has been checked and certified as safe by a competent person as outlined in the Scaffolding Best Practice Guidelines for Scaffolding in New Zealand.
Where work is performed using mobile scaffolds, employers should ensure that workers understand that the scaffold should:
- › be erected by a competent person and used in accordance to the manufacturer’s specifications
- › remain level and plumb at all times
- › be kept at least one metre from open floor edges and openings unless the edge is protected to prevent the scaffold tipping
- › never be accessed until all the castors are locked to prevent movement
- › never be moved while anyone is on it
- › be clear from overhead powerlines.
Scaffolds must have:
- › the height to the top-most platform not greater than three times the minimum base dimension
- › safe access
- › stable foundations
- › stable and safe work platforms and enough room to work.Where a scaffold is used as a means of protecting people working on a roof, it is preferred that the scaffold is set up in a manner that prevents a fall from occurring, regardless of the distance of the fall.For further information on the safe selection, erection and use of scaffolds, including suspended work platforms, refer to the AS/NZS 1576.1 – 6 Scaffolding Series, and Scaffolding Best Practice Guidelines for Scaffolding in New Zealand.
6.2 Edge protection
Edge protection is used to prevent persons, objects or materials from falling.
Areas where the likelihood of a fall exists and edge protection should be used include:
- › perimeters of working places
- › openings
- › where there is brittle material that cannot safely support the weight of a person. Edge protection may be temporary, for example during the course of construction. It may also be used in completed buildings, for example a permanent balustrade preventing a fall from a mezzanine floor.
Reduce the gap to 100 mm or less from gutter where practicable. Maximum permissible 200 mm from guttering to guardrails
Guardrail within 200 mm of roof projection
Note: A dogleg brace can be used to stabilise the extended standard
Integrity of the edge protection
Edge protection may involve:
- › a proprietary (engineered) system
- › materials to form a guardrail and/or physical barriers
- › erected scaffolding that supports a temporary edge-protection system
- › a combination of solutions.
Ensure edge protection is:
- › erected, used and maintained in accordance with its design information
- › regularly inspected by a competent person
- › inspected after a storm or other occurrence that could affect its purpose to prevent falls
- › free of any defects before use.
Erecting edge protection
Persons erecting edge protection could potentially be exposed to the hazard of working at height until the installation is completed. Pre-planning, such as a task analysis and a hazard analysis, will identify the hazards involved and which controls can be implemented to prevent harm during the erection process. Installation workers must have hazard controls in place.
A guardrail is a barrier that is capable of physically preventing workers from falling. Guardrails are a group control that can be installed to protect workers from building edges, roof edges, building openings, lift shafts and other similar ducts with wall or floor openings.
A guardrail must be constructed to withstand the forces that are likely to be applied to it during as a result of the work. Temporary guardrails should generally be constructed using a proprietary metal tube and clip system.
General guardrail systems shall be between 900 mm and 1100 mm in height with a single mid rail located halfway between the work platform and the top rail. If there is a potential for tools or objects to be dropped during work, a toe board should also be installed. Refer to the Scaffolding Best Practice Guidelines for Scaffolding in New Zealand.
Guardrail systems that are installed to protect an edge of a sloping roof surface have specific design requirements because of the increased potential for workers to fall against them and the potential for a person to slip under the mid rail.
Guardrail systems for sloping roofs shall be configured to prevent a worker sliding between the roof surface and the rails. It is important that such systems are installed by a competent person. For guidance on the configuration of such edge – protection systems refer to the standard AS/NZS 4994.2:2009 Temporary edge protection – Roof edge protection – Installation and dismantling.
If the slope of the roof exceeds 25 degrees, a roof ladder should be used in addition to perimeter guardrails (or a harness system) to reduce the likelihood of worker slipping.
Floor openings may also be protected by a fit-for-purpose, fully decked working platform. Work inside of shafts should, when practicable, be undertaken from a fully decked working platform; if this is not practicable, a harness system shall be used.
Barriers to restrict access (also known as bump rails):
Barriers should be used to cordon off elevated areas including roofs, balconies and open excavations where edge protection is not provided and people are not permitted access. The barriers should be secure and with access restricted to authorised people only. Signs should warn against entry to a cordoned-off area.
Barriers should be placed at least two metres in from any unprotected edge or opening. They should be highly visible and capable of remaining in place during adverse weather conditions.
Installing timber temporary edge protection:
Temporary timber guardrails are sometimes used for edge protection. Timber edge protection shall be constructed by a competent person and extreme caution is required to ensure the appropriateness of all materials used. Construction must take into account the forces that are likely to be applied to the edge protection as a result of the work undertaken.
