INTRODUCTION
Please read this guide carefully.
Please note that diagrams are for illustrative purposes
only.
User guides are also available to download from our
website at youngmangroup.com
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 Youngman BoSS mobile tower must have a copy of this
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
guides or any other help with this product, please contact

PREPARATION AND INSPECTION
Inspect the equipment before use to ensure that it is not
damaged and that it functions properly. Damaged or incorrect
components shall not be used.
SAFE USE
Check that all components are on site, undamaged and
that they are functioning correctly – (refer to Checklist
and Quantity Schedules). Damaged or incorrect
components shall 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 275 kgs (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 trap door 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.
LIFTING OF EQUIPMENT
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.

STABILISERS / BALLAST
Stabilisers or outriggers and ballast weights shall always
be fitted when specified.
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.
MOVEMENT
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 fitted, 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).

Safety First
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 (17 mph), 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.

Do not abuse equipment. Damaged or incorrect
components shall 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 20 kg.
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.

Safety First
TIES
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 Youngman.
MAINTENANCE - STORAGE - TRANSPORT
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 windlocks should be regularly checked to
ensure they lock correctly.
Refer to the BoSS Inspection Manual 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.

1450 Width Towers
NUMBER OF WORKING PLATFORMS ALLOWED
The MAXIMUM SAFE WORKING LOAD (the combined
weight of the users, tools and materials) that may be
placed on the tower is the total weight less the self weight
of the tower. The total weight for the towers shown in the
schedule is 950kg.
Example 1:
A 1450 Clima tower built using the AGR method with a
4.2m platform height and a platform length of 1.8m has a
self weight of 201kg.
950kg — 201kg =749kg maximum safe working load
total weight self weight (users, tools and materials)
Example 2:
A 1450 Clima tower built using the AGR method with a
11.7m platform height and a platform length of 2.5m has a
self weight of 548kg.
950kg — 548kg = 402kg maximum safe working load
total weight self weight (users, tools and materials)
For greater heights and loads, consult Youngman for
guidance.
PLATFORM LOADING
On a 1450 tower a platform may comprise of a single
deck or two decks placed side by side. The maximum safe
working load (the combined weight of the users, tools and
materials) that may be placed on a platform is 275kg. This
must be evenly distributed over either one deck, or two
decks placed side by side.
The quantities on page 9 will enable BoSS towers to be
built safely and therefore comply with the requirements
of the Work at Height Regulations. They include double
guardrails to all platforms, and toeboards will need to be
added if any levels are used as working platforms and for
storage of materials.
EN 1004 requires platforms at least every 4.2m, and these
measures will exceed that requirement.

NUMBER OF WORKING PLATFORMS ALLOWED
The MAXIMUM SAFE WORKING LOAD (the combined
weight of the users, tools and materials) that may be
placed on the tower is the total weight less the self weight
of the tower. The total weight for the towers shown in the
schedule is 950kg.
Example 1:
An 850 Clima tower built using the AGR method with a
4.2m platform height and a platform length of 1.8m has a
self weight of 158kg.
950kg — 158kg = 792kg maximum safe working load

Example 2:
An 850 Clima tower built using the AGR method with a
10.2m platform height and a platform length of 2.5m has a
self weight of 348kg.
950kg — 348kg = 602kg maximum safe working load
total weight self weight (users, tools and materials)
For greater heights and loads, consult Youngman for
guidance.
PLATFORM LOADING
On an 850 tower a platform comprises of a single deck
only. The maximum safe working load (the combined
weight of the users, tools and materials) that may be
placed on a platform is 275kg, evenly distributed over the
deck.
The quantities on page 12, will enable BoSS towers to be
built safely and therefore comply with the requirements
of the Work at Height Regulations. They include double
guardrails to all platforms, and toeboards will need to be
added if any levels
are used as working platforms and for storage of materials.
EN 1004 requires platforms at least every 4.2m, and these

Assembly Procedure
AGR Method
ASSEMBLY AND DISMANTLING PROCEDURES
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 first 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:

Stabilisers and Outriggers
Mobile Towers - AGR Method
STABILISERS
Attach one stabiliser to each corner of the tower as shown. Ensure
stabiliser feet are equally spaced to form a square.
SP10 and SP15 telescopic stabilisers must always be fully
extended.
Position the lower clamp so that the lower arm is as close to the
horizontal as possible. Adjust the position of the top clamp to
ensure the stabiliser foot is in firm contact with the ground. Ensure
clamps are secure.
Stabilisers are used when the tower is to be moved occasionally,
frequent movement will require mobile outriggers.
When moving the tower, adjust the top clamps to lift the four
stabiliser feet a maximum of 25mm off the ground and then
unlock the castor brakes. After moving ensure all four stabiliser
feet are repositioned in firm contact with the ground.
