Persons using this scaffold should be provided with a copy of this document.

This scaffold meets the standards of Appendix B, Appendix C and Appendix E of ASNZS1576.3 2015 Prefabricated and Tube and Coupler Scaffolding.

These instructions provide general guidance for scaffold users on safe means of erection, these instructions may not be suitable for all sites and configurations.

Users must inspect all equipment prior to erection to verify that it is not damaged. Any damaged equipment should be tagged as damaged and removed from the place of work to ensure that it is not used. These instructions relate only to the use of Ringlock scaffold supplied by ScaffoldMe.

Scaffolding should be transported, erected and dismantled by persons who are qualified/competent to do so. For guidance on appropriate qualifications/competency please refer to “Scaffolding – Best Practice Guideline for Scaffolding in New Zealand”, available from Worksafe New Zealand.

Users of this scaffold should develop task specific hazard assessments prior to using the scaffold. It is recommended that as part of this task specific hazard assessment, appropriate minimum Personal Protective Equipment is identified. For persons transporting, erecting and dismantling this scaffold this should include (as a minimum) hard hat, safety glasses, steel toe boots and gloves.

Limitations:

The maximum design height for this scaffold is 30m. This scaffold is classed as Heavy Duty (with a maximum platform capacity of 6.6kN (approx 660 kgs), including a concentrated point load not exceeding 2kN (approx. 200 kgs). A maximum of one platform within each bay should be used as a working platform at a time – the remaining bays (above and/or below) should be closed off or otherwise marked as “out of duty”. The scaffold should not be erected to heights in excess of those specified or for duty ratings greater than those set out above unless proven safe to do so by a suitably qualified person. All users of the scaffold should be instructed on the safe working loads outlined herein.

Care of Scaffold

Although the scaffold is designed to be used outdoors, to ensure that your scaffold remains in the best possible condition, we recommend that all components are stored flat on dedicated racks or stillage and covered where possible to prevent excess exposure to weathering (especially salt spray) when not in use. Scaffold should not be left stacked on bare ground where moisture is expected.

The protective surface (galvanised) is prone to wear and tear, and as such visual inspection and periodic maintenance of this coating is recommended to ensure the life of the scaffold is maximised. Any noticeable damage to the galvanised surface should be cleaned and repaired with suitable rust inhibiting primers/paints in accordance with manufacturer’s instructions.

Scaffolding components are heavy and may require multiple persons to lift safely. When moving scaffolding components, items should not be dropped or thrown. When transporting scaffold, dedicated stillages should be used to reduce the likelihood of damage to the scaffold.

RINGLOCK NODE CONNECTION

Ringlock node connection consists of standards with rosettes every 0.5m and horizontal members with a cast end captive wedge (Ledger/Transom). When connected together the ledger ends and rosettes create a very strong connection. It is this connection that transmits forces throughout the scaffold structure

The Ringlock rosette has been manufactured to have 8 holes, 4 of which are small and 4 are large. The smaller holes represent the 90 degree angle at which Ledgers/Transoms are fitted. The larger holes accommodate the diagonal bay braces and ledgers at variable angles.

The rosette also allows for the Ledgers to be connected into the larger holes which gives up to 15 degree of manoeuvrability.

TO MAKE A CONNECTION

Slide Ledger head over the hole in the rosette that is to be used Rotate wedge and insert through hole in rosette Hammer home wedge to secure in place to create a strong and rigid connection

Typical Erection Process

In order to meet New Zealand Best Practice Guidelines, Scaffold must be erected on suitable ground (refer to sections 2.8.1.1 and 3.3 of the guidelines for specific details on suitable ground), and timber sole boards (sole boards should be sized in accordance with New Zealand Best Practice Guidelines section 3.3). Sole boards are not shown in photos.

Step 1. Position sole boards at the planned locations of the adjustable base jacks. Starting at the highest end of the scaffold first, position the adjustable base jacks, base collars and O-ledgers. Set the heights of the adjustable base jacks to ensure the scaffold is level. Adjustable base jacks should be set at the lowest level possible and must not be set more than 500mm high – this is to ensure that at least 150mm of the base jack spigot remains inside the vertical standards.

Step 2. Position the vertical standards inside the base collars/over the adjustable base jacks.

Step 3. Position deck ledgers in the rosettes at the height of the first working platform, this should be no greater than 2m above the height of the base collars.

Step 4. Position long O-ledgers in the rosettes at the height of the first working platform, and 0.5m below the working platform. These will form a handrail and midrail for a temporary platform.

Step 5. Position deck ledgers in the rosettes 1.0m below the first working platform. Place steel decks inside these to provide a temporary platform 1.0m below the working platform.

Step 6. From the temporary working platform, position long O-ledgers in the rosettes at 0.5m and 1.0m above the height of the first working platform. These will form a handrail and midrail for the working platform. Midrails and handrails should always be positioned in rosettes 0.5m and 1.0m respectively above the working platforms. Handrails and midrails must also be fitted to the inside face of any scaffold platform (temporary or working platform) that is greater than 300mm from the building to the platform edge.

Step 7. Remove the steel decks from the temporary work platform and place steel decks in the working platform. Remove the deck ledgers from the temporary work platform level, remove the temporary work platform midrail and handrail*. Repeat steps 3-7 for all bays in the first working platform.

* If steel decks with lift off covers are used then long O-ledgers are not required at deck level.

Step 8. Install diagonal bracing at a minimum frequency of 1 brace per 4 bays. From the working platform, install the deck lift off covers to prevent steel decks from shifting.

Repeat steps 2-8 to create second and subsequent lifts paying attention to anchor requirements. (The scaffold must be anchored to a building or otherwise secured by extending the minimum base dimensions to prevent taller scaffolds from tipping over).

IMPORTANT NOTE:

Anchoring should be secured to vertical standards at each working platform level above the first working level. Scaffold anchoring must take into consideration the type of building facades, the strength of the building and the fasteners used. Anchor forces should be calculated according to local codes or regulations and should consider the scaffold plus drag created by presence of toe boards, netting or tarpaulin/shrink wrap. Refer to section 4.5 of the Best Practice Guidelines for Scaffolding in New Zealand for minimum tie specifications.
