ASSEMBLY PRINCIPLES
The manufacturer recommends that 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.
Always start building with the smallest height frames at the base
of the tower:
850 & 1450 towers:
Platform height in metres Frame at base
2.2, 4.2, 6.2, 8.2, 10.2, 12.2 4 rung
2.7, 4.7, 6.7, 8.7, 10.7 6 rung
3.7, 5.7, 7.7, 9.7, 11.7 4 & 6 rung
ASSEMBLY PROCEDURE
AGR Method
Push four castors onto four adjustable legs. Insert adjustable
1
legs into two end frames as shown. Lock castor brakes.
Base plates can be fitted to adjustable legs if it is not necessary to
move the tower.
Unlocked
Locked
Fit an AGR on both sides of the tower. The bottom of
5
the AGR must be fitted to the 6th rung of the tower, as
shown. The AGR should be placed up against the end frame
verticals.
Continue to add pairs of end frames, AGRs and fit decks as
9
shown in the previous steps.
Continue until the required height is reached.
Where all three frame 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 the top. Refer to the Quantity Schedules for
detail. The procedure illustrated shows a 1450 tower starting
with a 4 rung frame and a platform height of 4.2m. If building an
850 tower, the following method can be used with single decks
at all levels.
Fit one horizontal brace (red) onto the vertical of an end
2
frame, just above the bottom rung, with the claw facing
outwards.
Note: All locking claws must be opened before fitting.
Locked
Fit the stabilisers. If required, fit a temporary deck on the
6
lowest rungs of the tower. Fit a trapdoor deck on the 8th
rung on one side of the tower. Ensure the trapdoor is positioned with
the hinges towards the outside of the tower as shown. Fit a fixed
deck next to the trapdoor deck on the 8th rung. The platform is now
complete. Climb the end frame below the trapdoor on the inside of
the tower.
If fitted, remove the temporary deck from the lowest rungs.
Fit the toe boards - see the components section for guidance
10
on how to fit.
The tower is now complete.
During use
Beware of high winds in exposed, gusty or medium breeze conditions. We recommend that in wind speeds over 7.7 metres per second
(17mph), cease working on the tower and do not attempt to move it. If the wind becomes a strong breeze, (expected to reach 11.3 metres per
second - 25 mph) tie the tower to a rigid structure. If the wind is likely to reach gale force, (over 18 metres per second - 40 mph) the tower
should be dismantled.
Wind description Beaufort scale
Medium breeze Raises dust and loose paper, twigs snap off
Strong breeze Large branches in motion, telegraph wires whistle
Gale force Walking is difficult
• Beware of open-ended buildings, which can cause a funneling effect.
• Raising and lowering components, tools, and/or materials by rope should be conducted within the tower base. Ensure that the safe working
load of the supporting decks and the tower structure is not exceeded.
• The assembled tower is a working platform and should not be used as a means of access or egress to other structures.
• Beware of horizontal forces (e.g. power tools) which could generate instability.
• The stairway towers, featuring an inclined staircase access, are for frequent use by personnel carrying tools and/or materials.
• Do not use boxes or stepladders or other objects on the platform to gain extra height.
Position the second end frame as shown and fit the other
3
end of the horizontal brace on to the vertical, just above the
bottom rung. Fit a second horizontal brace on the bottom rungs on
the other side of the frames to square the tower.
NOTE: The following diagrams show the tower without
stabilisers to improve clarity of views.
Fit two additional end frames.

DISMANTLING PROCEDURE
To take down the tower reverse the building sequence. Unlock the
camlocks at the bottom of the AGR frame, then lift off the AGR from
the end frames.
Beaufort no. Speed in mph Speed in m/sec
4 8 - 12 4 - 6
6 25 - 31 11 - 14
8 39 - 46 17 - 21
Maximum horizontal force 20kg.
Fit two additional end frames and check the frame
4
interlock clips are engaged. Fit two diagonal braces (blue)
in opposing directions, from the 2nd rung to the 6th rung on the
opposing side. Ensure the frames are vertical and level by checking
with a spirit level and setting the adjustable legs as required.
IMPORTANT - Only use the adjustable legs to level the tower
and not to gain extra height.
INTERLOCK CLIP
Locked Unlocked
Fit two more AGRs to the end frames, with the top claws on
8
the 20th rungs. Fit a trapdoor deck on the 16th rung, with the
trapdoor in line with the one below. Place a fixed deck on the 16th
rung next to the trapdoor deck.
The tower now has a platform height of 4.2m. If finishing at this
height, move on to Step 10. If greater platform heights are required,
move on to Step 9.
