12. ASSEMBLY WITH BRACKETS

Please refer to the table of tower models on page 8 to see which
tower models are allowed to be extended with brackets.
When brackets are used, the following points must be noted in addition:
– The tower may be loaded with 1.5 kN/m
working level only.
– The spindles must not be overextended.
– The corresponding working platform must be equipped with
complete side protection.
– The ladder frames must be assembled in the centre position.
The corresponding ballast weights (see ballasting table on p. 8 – 10)
must be attached before itting the brackets.
– A maximum of 2 bracket deck surfaces can be itted to a tower.
The bracket deck surfaces can be used either on one side, both on
one side or one on each side.
– The bracket deck surfaces can be itted at any level of the tower
where a deck is provided.
WARNING
If the ballasting table is not complied with, there is an increased risk of
accidents as a result of the tower tipping over due to one-sided loading.

(scaffold group 2) at one
1. Tower assembly up to the height required in accordance with
the assembly sequence already described (see page 11 ff.).
2. Before itting of brackets, remove the side protection at a height
of 0.5 m and the toe boards at this point.
3. At the access level, bolt on 2 brackets at each side using the
couplers in such a way that the rungs of the aluminium brackets
0.75 m are at the same level as the ladder frame rungs.
4. Now suspend the deck from the bracket rungs.
5. Fit a 1 m ladder frame onto each of the brackets 0.75 m and then
mount the side protection removed earlier at a height of 1 m.
The guardrail still remaining on the tower can be itted at a
height of 0.5 m
6. Place the intermediate deck 2.85 m between the deck and the
access deck and snap it into the bracket rungs 0.75 m.
7. Complete the regulation side protection, which depends on the
tower model concerned, by itting and adjusting the toe boards
2.85 m between the ladder frames on the bracket and secure them
by inserting end toe boards.
8. To attach a second bracket deck surface, repeat the steps 2 – 7.
Dismantling
Dismantling of the brackets is in the reverse order to that of the
assembly steps. After removal of the brackets, the entire tower can
be dismantled as described in "Dismantling" on page 16.
