Page 8: Assembly
Assembly Procedure A minimum of two people is required for the assembly of the 850/1450 tower. Only climb the tower from the inside using the ladder section. Always start building with the smallest height frames at the base of the tower: For even platform height towers (2.2m/4.2m/6.2m etc) ALWAYS start with a 2 RUNG... - Page 9 Assembly (cont’d) Insert 4 rung frames to correspond with the 2 rung frames (see below) and lock the locking clips (refer to page 5). Attach diagonal braces on both sides from the 1st rung to the 3rd rung of the structure, in opposite directions. Place a solid deck platform on the 1st rung* and a trap door platform on the 4th rung, both on the ladder side of the structure.
- Page 10 Assembly (cont’d) Attach stabilisers as required for working height (see page 15). Climb the ladder and from a protected through the trapdoor position, attach horizontal guardrail braces to the 5th and then 6th rungs, on both sides of the platform. Never climb onto a platform that is not fully guardrailed.
- Page 11 Assembly (cont’d) Attach 2nd pair of diagonal braces following on from those fitted in step 4. Attach the next 4 rung frames and lock clips (see below).
- Page 12 Assembly (cont’d) If completing the tower at this height (4.2m platform height), continue with step 8. When building beyond this level, repeat steps 4, 5 and 6 until desired level is achieved, then complete the tower with steps 8 and 9. When building the tower with a platform height of over 4.2 metres, remove the first platform and 4 horizontal braces that accompany it and use these to complete the structure.
- Page 13 Assembly (cont’d) Fit the final diagonal braces as shown. This stage will provide a platform height of 4.2m. Attach diagonal braces (see below). The fixed platform should be moved up to the 8th rung and moved across to the far side of the structure, the trapdoor platform can now be fitted alongside it.
- Page 14 Assembly (cont’d) Fit toe boards to all working platforms (see instructions on page 4). When building the tower with a platform height of over 4.2 metres, remove the first platform and 4 horizontal braces that accompany it and use these to complete the structure. When building the tower with a platform height of over 8.2 metres, remove the first and third platform from the base, along with the accompanying horizontal braces and use these to complete structure.
