Assembly Procedure
Mobile towers - 850 3T method
Assembly for 850 towers
Always start building with the smallest height
frames at the base of the tower:
Platform height in metres
1.7, 2.2, 3.7, 4.2, 5.7, 6.2, 7.7, 8.2, 9.7, 10.2, 11.7, 12.2
2.7, 4.7, 6.7, 8.7, 10.7
1.2, 3.2, 5.2, 7.2, 9.2, 11.2
Where all 3 Heights are used in a tower, start with 4 rung frames at
the base, with the 6 rung frames next and the 8 rung frames on top.
Refer to the quantity schedules for detail. The procedure illustrated
shows a tower starting with an 8 rung frame.
Insert adjustable leg/castor assemblies into end frames and
1
lock the castors, (see diagram Step 1 - page 17). Base plates
can be fitted to the adjustable legs if it is not necessary to move the
tower. Fit two horizontal braces to the 850 end frames as shown in
steps 2 and 3 for the 1450 tower procedure (page 18). Ensure that
the frames are vertical and level by checking with a spirit level and
setting the adjustable legs required.
Fit a trapdoor deck on the 4th rung. Fix the horizontal braces
2
(red) as guardrails on the 6th and 8th rungs (2 and 4 rungs
above the platform) on both sides of the tower.
