Always start building with the smallest height
frames at the base of the tower:
Platform Heights in Metres
Frame
at Base
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 rung
2.7 4.7 6.7 8.7 10.7
3 rung
1.2 3.2 5.2 7.2 9.2 11.2
4 rung
Where all 3 frame heights are used in a tower, start with 2 rung
frames at the base, with the 3 rung frames next and the 4 rung
frames on the top. Refer to the quantity schedules for detail. The
procedure illustrated shows a tower starting with a 2 rung frame.
Youngman recommend two persons are used to build
BOSS towers. Above 4m height it is essential that at
least two persons are used. Only climb the tower from
the inside.
1
Push castor onto adjustable
leg. Insert adjustable
leg/castor assemblies into 2
rung span frame. Lock
castors. Repeat with ladder
frame. Base plates can be
fitted to adjustable legs if it is not necessary to move the tower.
2
Fit a horizontal brace (red) onto the vertical of the span frame,
facing claws outwards. The frame will now be self-supporting.
Note:
All locking claws must be opened before fitting.
3
Position ladder frame as shown.
Fit the other end of the horizontal
brace onto the ladder frame
