Building the Tower Fit the next pair of diagonal braces in opposing directions between the 3 and 5 rungs. Add two additional end frames. Add two more diagonal braces between the 5 and 7 rungs. If finishing at this height (4.2m platform) reposition the fixed deck to the 8 rung on the tower.
Page 17
Building the Tower Continue to add pairs of end frames, diagonal braces and fit trapdoor decks as shown in the previous steps. Add guardrails at 0.5m and 1.0m, (in that order), above the platform from the protected trapdoor position. Do not climb onto the deck until all guardrails are in place.
Building the Tower 2.5.2 Assembly for 850 Towers The procedure illustrated shows a 3.2m platform height tower starting with a 4 rung frame. Insert adjustable leg/castor assemblies into end frames and lock the castors (see diagram Step 1 - page 11). Base plates can be fitted to the adjustable legs if it is not necessary to move the tower.

Building the Tower Climb up the inside of the tower and from the protected position of the trapdoor, fit guardrails to the 7 rungs (in that order) on both sides of the tower. Continue the procedure until the required working height is reached, adding additional pairs of end frames, diagonal braces and fitting trapdoor platforms, as shown on previous...
