•
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.
Maximum horizontal force 30kg.
•
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.
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.
ASSEMBLY PROCEDURE
From the ground level, position a
trapdoor deck on rung 8. Engage
the wind-locks. Locate assembly bracket
No. 1 on front face of lowest camlock
guardrail. Locate the second
assembly bracket on rung 10 of the
end frames.
6
Hang four camlock guardrail units in order on the front
assembly bracket and then 1 x folding toe board. Place the
last camlock guardrail on the end frame assembly bracket No 2.
Hang two pairs of connected 4 rung frames on the end bracket No 2.
then hang the second trapdoor deck on the bracket.
Climb the tower from the inside and from a protected
position on the trapdoor. Reach to the side bracket and take
one camlock guardrail. Position the guardrail on the rear of the tower
as shown. All guardrails should fix to the 2nd and 4th rung above
the platform deck. Repeat with second camlock guardrail frame on
the front of tower to fully secure platform. Engage and lock camlock
claws.
Do not climb onto the platform until guardrails are in place.
8

bossaccesstowers.com/literature
Standing up on the protected platform, lift the second
trapdoor deck onto the platform. Store by the rear guardrail
clear of the end frames.
9
Add the connected pairs
of end frames taking care
to engage the locking clips. Add a
camlock guardrail to rungs 13 & 15
and lock.
10
Remove the end frame
assembly bracket from
rung 10 of the end frame and
re-position on the top camlock.
Position the folding toe board
set and then the remaining
two camlock frames on the
uppermost bracket.
11
Place the trapdoor deck onto the 16th rung of the tower and
engage wind-locks.
Climb the end frame from within and from the protected trapdoor
position, fit the camlock guardrails as shown.

•
To comply with the ‘Work at Height Regulations’, we show
assembly procedures with platforms every 2 metres in height
and the locating of guardrails (in advance of climbing onto a
platform) to increase safety and reduce the risk of a fall.
•
Never stand on an unguarded platform positioned above the first
rung of a tower. If your risk assessment shows it necessary, you
may also need to add guardrail platforms at this level.
The procedure illustrated shows a 6.2m working height tower.
Insert castor into adjustable leg. Apply brake by pushing The
lever down, release frame interlock clips and fit the leg and
castor assembly into a 1m base frame. Repeat with the remaining
legs and castors. Adjustable legs should only be used for levelling.
1
FOLDING BASE METHOD:
Release brakes on castors at one end frame until the locks
engage on the rear folding frame.
Ensure both hinges positively lock into position. Engage brakes on
second frame.
2
Locate the horizontal brace on the lowest rung with the
hooks facing downwards - check the brace is correctly
locked on the tube at both ends. Check the base unit is square and
level using a spirit level. Adjust legs only to level and not to gain
additional height.
3
STEP 1: Connect two 4 rung frames together. Check the
interlock clips are engaged and add onto the base unit.
Repeat for the other side.
STEP 2: Position one camlock guardrail unit. The top hooks should
locate on the 7
th
rung from base level.
STEP 3: Engage camlocks as shown to lock guardrail unit in
position.
4
Fit stabilisers to tower before extending
telescopic leg. Position top clamp above rung 6,
second clamp locates above rung 2. Extend telescopic leg
by removing the interlock clip. Slide the leg out until the leg
reaches the ground. Rotate the leg until the interlock clip
holes line up. Lock the leg by using the interlock clip and
adjust the stabiliser to ensure the stabilisers are engaged.

Unclip the storage strap from the folding toe board set,
unfold and fit the toe board into position on the working
platform. Move assembly brackets to base of the tower and fit to the
lowest rungs of the end frames.

DISMANTLING PROCEDURE
Simply follow the assembly steps in reverse, ensuring that the 3T
method is followed.
STORAGE TROLLEY
ASSEMBLY
Assemble the folding base frame with one trapdoor deck
placed on the bottom rung forming the base of the trolley.
Lower all adjustable legs as far as possible.
1
Fit the folding toe board set to the trapdoor deck.Position
the 1.3m horizontal brace on the front upright, just above
the 4
th
rung.
Place the assembly brackets, one at each end on the inside of the
folding base unit end frames.
2
Place the camlock frames,
three at either end within the
trolley. Ensure the diagonal struts of
the camlock frames fit between the
arms of the assembly brackets.
3
Place the 1m end frames
in the centre of the trolley
between the guardrail frames.
4
Add the final trapdoor deck
in front of the 1m end frames.
Fit the four SP4 stabilisers in front of
the trapdoor deck.
The trolley unit is now complete.

The BoSS SOLO
700
system has been developed so that a single
person can safely build the tower to a platform height of 4.2m.
