BoSS Mobile Aluminium Towers are light-weight scaffold towers
used throughout the building and construction industry for both
indoor and outdoor access solutions where a stable and secure
platform is required. Ideal for maintenance and installation work
or short-term access, the highly versatile towers provide a strong
working platform for a variety of heights.
This user guide provides you with step by step instructions to
ensure your system is erected easily and safely, using the AGR
(Advance Guard Rail) method.
The law requires that personnel erecting, dismantling or altering
towers must be competent. Any person erecting a BoSS Mobile
Tower must have a copy of this user guide. For further information
on the use of mobile access and working towers consult the
PASMA operators’ code of practice.
If you need further information, design advice, additional
user guides or any other help with this product, please
contact the manufacturer on [phone] or email

Check that all components are onsite, undamaged and that
they are functioning correctly - (refer to Checklist and Quantity
Schedules). Damaged or incorrect components should not be
used.
Check if the ground on which the mobile access tower is to be
erected and moved is capable of supporting the tower.
The safe working load is 275kgs (606lbs), per platform level,
uniformly distributed up to a maximum of 950kgs (2100lbs), per
tower (including self-weight).
Towers must be climbed from the inside using the rungs
directly below the trapdoor during assembly and use.
It is recommended that towers should be tied to a solid
structure when left unattended.
Adjustable legs should only be used for levelling.
Tower components should be lifted using a reliable lifting
material (e.g. strong rope) employing a reliable knot (e.g. clove
hitch) to ensure safe fastening and always lift within the footprint
of the tower.
Assembled mobile towers should not be lifted with a crane or
other lifting device.
Safety First
Preparation and inspection
Safe use
Inspect the equipment before use to ensure that it is not
damaged and that it functions properly. Damaged or incorrect
components should not be used.

Stabilisers or outriggers and ballast weights should always be
tted when specied.
The Quantity Schedules show the recommended stabilisation.
In circumstances where there is restricted ground clearance for
stabilisers/outriggers, contact your supplier for advice. Ballast
must be of solid materials (i.e. not water or loose sand) and
should not be positioned to overload individual legs. Ballast
should be secured against accidental removal where practicable,
and be supported on the lowest rung of the bottom frame.
The tower should only be moved by manual effort, and
only from the base.
When moving the tower, beware of live electrical apparatus,
particularly overhead, plus wires or moving parts of machinery.
No person or materials should be on the tower during
movement.
Caution should be exercised when wheeling a tower over
rough, uneven or sloping ground, taking care to unlock and
lock castors. If stabilisers are tted, they should only be
lifted a maximum of 25mm above the ground to clear ground
obstructions.
The overall height of the tower when being moved,
should not exceed 2.5 times the minimum base dimensions, or 4
metres overall height.
Before use, check the tower is still correct and complete.
After every movement of the tower use a spirit level to
check that it is vertical and level and set the adjustable legs as
required.
Do not move the tower in wind speeds over 7.7 metres
per second (17mph).

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 (25mph), tie the tower
to a rigid structure. If the wind is likely to reach gale force, over
18 metres per second (40mph), the tower should be dismantled.

Beware of open-ended buildings, which can cause a funnelling
effect.
Do not abuse equipment. Damaged or incorrect components
should not be used.
Raising and lowering components, tools, and/or materials by
rope should be conducted within the lower 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.
Mobile towers are not designed to be suspended - please refer
to your supplier for advice.
Do not use boxes or stepladders or other objects on the platform
to gain extra height.

bossaccesstowers.com 6
Ties should be used when the tower goes beyond its safe height,
beyond the limits of the stabilisers/outriggers, or if there is a
danger of instability. They should be rigid, two way ties fastened
to both uprights of the frame with load-bearing right angled or
swivel couplers. Only couplers suitable for the 50.8mm diameter
tube of the tower should be used. Ideally, ties should be secured
to both faces of a solid structure by means of anchorages.
The tie frequency may vary depending on the application, but
they should (at a minimum) be every 4 metres height.
For further information on tying-in a tower please contact your
supplier or [email protected].
All components and their parts should be regularly inspected to
identify damage, particularly to joints. Lost or broken parts should
be replaced, and any tubing with indentation greater than 5mm
should not be used and put to one side for manufacture repair.
Adjustable leg threads should be cleaned and lightly lubricated to
keep them free running.
Brace claws, frame interlock clips, trapdoor latches and platform
wind-locks should be regularly checked to ensure they lock
correctly.
Refer to the BoSS User Guide for detailed inspection and
maintenance advice.
Components should be stored with due care to prevent damage.
Ensure components are not damaged by excessive strapping
forces when transported.

When building a BoSS Tower:
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 reduce the risk of a fall.
All platforms feature double guardrails on both faces of
either individual platforms or fully decked levels.
All guardrails should be 2 and 4 rungs (0.5m and 1.0m)
above platforms.
Never stand on an unguarded platform positioned above
the rst rung of a tower. If your risk assessment shows it
necessary, you may also need to guardrail platforms at this level.
Always start building with the smallest height frames
at the base of the tower:
