- Page 3 Scaffold Introduction and Guideline_TUV Stability of Scaffold Scaffold Users A scaffold should not be used unless it is properly constructed and is suitable for the purpose for which it is required and has been inspected. Where the scaffolding exceeds 2m in height, each contractor (including subcon- tractors and the self-employed) should be satisfied that the scaffold has been inspected by a competent person within the previous 7 days and should therefore ask to see the report of the inspection.
- Page 4 Scaffold Introduction and Guideline_TUV Promptly report defects in the scaffold to whoever is in control of the scaffold Not leave a scaffold in a hazardous condition for current or subsequent users Check all parts, auxiliary tools and safety equipment( helmet, ropes ...) are available on site.

- Page 6 Scaffold Introduction and Guideline_TUV How to move scaffolding Tower Step Before moving the scaffolding tower, make sure everyone has left the rack and clean up all the debris. No person or materials should be on the tower during movement. Tower should be reduced in height to 4m platform height before movement. Release the support of the outriggers to a half height from the ground (ie 12 mm) Determining the safety of the tower route and having sufficient height to avoid...
- Page 7 Scaffold Introduction and Guideline_TUV Inspection Before and During Use Scaffolds should be inspected before use and again at least every 7 days and after any circumstance that might affect the stability or safety of the scaffold. Such circum- stances include: Modification Period without use Exposure to bad weather...
- Page 8 Scaffold Introduction and Guideline_TUV A report of the inspection should be made on a suitable form and a copy of the report should be retained on site. It is not allowed to extend the height of the platform by the use of ladders, boxes or other devices.

- Page 10 Scaffold Introduction and Guideline_TUV NUMBER OF WORKING PLATFORMS ALLOWED & PLATFORMS ALLOWED Load Path: To following the EN1004:2004, the gravity loads has designed to including dead load, self-weight and uniform distribution load acting on the platform will be resist by the bending stress of the platform and then the loading will transfer to the alu- minium beams supporting the platform and then the loading will be transfer to the vertical aluminium elements and the bracings are added as restrain to the vertical members.
- Page 11 Scaffold Introduction and Guideline_TUV Uniform distributed load 2.0kN/m2 (Load Class 3) The Suppliers instruction manual will detail the maximum lads that the tower can support. The safe loading: Maximum Design Load supported on platform, e.g. 275kg. Maximum Design Load supported on whole tower, e.g. 950kg.
- Page 12 Scaffold Introduction and Guideline_TUV Vertical Alignment Using a spirit level to set the adjustable legs and check the frames are vertical and level. Connections - The Wellclaws Horizontal and diagonal bracing are fundamental in the structure of scaffolding, with claws locking them onto frames.
- Page 13 Scaffold Introduction and Guideline_TUV Connections - The Flames Install the next upper frames and check the frame interlock clips are engaged. Lifting of Components Tower components should be lifted using a reliable lifting material (e.g. strong rope), employ- ing a reliable knot (e.g. clove hitch), to ensure safe fastening and always lift within the foot- print of the tower.
- Page 14 Scaffold Introduction and Guideline_TUV Safety work macro code Use flow-through metal frame Mobile access tower, which can only be built or dismantled by qualified trainees The top guardrail frame of the mobile access tower shall not be less than 950 mm and not more than 1150 mm.
- Page 15 Scaffold Introduction and Guideline_TUV Ties Ties should be used when the tower goes beyond its safe height, beyond the limits of the stabilisers/outriggers, or if there is a danger of instability. When the tower is left unattended, it should be tied. For further information on tying-in a tower please contact your supplier or the manufacturer.

- Page 21 Scaffold Introduction and Guideline_TUV Before scaffold erection, the trained and competent workers should check the location of the scaffold to prevent hazards during erection and dismantling, moving with respect to the ground conditions, level and slope, obstructions and wind conditions. It shall be checked that all parts, auxiliary tools and safety equipment (ropes, etc.) for erect- ing the scaffold are available on site.
- Page 22 Scaffold Introduction and Guideline_TUV Place the platform onto the designated rung level. Make sure the trapdoor opening is put on a Laddaspan. Snap another pair of horizontal bracings onto the first and the second rungs of the frame. Install four stabilizers onto the tower. Install 2 rung frames with the detachable handrails.
- Page 23 Scaffold Introduction and Guideline_TUV Erection Procedure - Double-Width Scaffold Assemble the leg and castor / base plat combo and plug them into the base of frames. The safety lock has to be ‘clicked’ for completing the plugging. Stand up the frames and lock up the castors by applying the brake.
- Page 24 Scaffold Introduction and Guideline_TUV Guardrails All platforms need double guardrails. The guardrails should be 1 & 2 rungs (Double Guardrails) above platforms. (1 rung = 0.51m, 2 rungs = 0.97 m) Never stand on an unguarded platform positioned above the first rung of a tower. If your risk assess- ment shows it necessary, you may also need to guardrail platforms at this level.
