MiniMax
Mobile Aluminium Tower
USER GUIDE
Introduction Safe Use
This Assembly Guide is designed to provide you with step
bystep instructions to ensure that your system is erected
with themaximum of ease and safety. Before assembly,
please read thesafety notes. Operatives must be qualified
or competent toerect the tower. If the scaffold is passed
on to another personthey should also receive these
instructions. Consult the PASMA Guide for full information
on the use of Mobile Towers.
Checklist
Inspect components prior to erection
Inspect tower prior to use
Tower upright
Castors locked and legs correctly adjusted
Braces & platform level
Stabilisers fitted as specified
Platforms located & windlocks on
Handrails in place
Toeboards located
Refer to this checklist before using each time.
Check that all components are on site and that they are
functioning correctly – (refer to check list and quantities).
Check that the ground is level and capable of
supporting the weight of the strucure.
During erection it is recommended that a temporary
guardrail brace be employed.
The safe working load is 220 kgs per platform uniformly
distributed, 500kg per tower structure.
This must not be exceeded.
The tower should always be climbed from the inside.
Do not use boxes or step ladders on the platform to
gain additional height.
Lifting of Equipment
Components should be firmly secured by a reliable
lifting material (eg rope), employing a reliable knot to
ensure safe fastening and always lift within the tower.

Safety First
Stabilisers/Ballast
All 4 stabilisers must be fitted when specified.
When using the 1.7m tower externally, 4 small stabilisers
must be fitted.
In circumstances where there are ground restrictions for
stabilisers to be positioned as specified, ballast may be
required, contact your supplier for advice.
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.
The height of the tower, when being moved, should not
exceed 3.7 metres. Max free standing height 5.8 metres.
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 m.p.h.), cease working on
the tower. If the wind becomes a strong breeze, expected
to reach 11.3 metres per second (25 m.p.h.), tie the tower
to a rigid structure. If the wind is likely to reach gale force,
over 18 metres per second (40 m.p.h.), the tower should
be dismantled.

Beware of open ended buildings, which can cause
funnelling effect.
Do not abuse equipment. Damaged or incorrect
components should never be used.
The assembled tower is a working platform and should
not be used as a means of access to other structures.
Beware of horizontal forces (eg power tools) which
could generate instability. Maximum horizontal force 20 kg.
Ties
When ties are required, they should be rigid (ie solid
tube and couplers).
Always tie to a solid structure.
The tie frequency should be at every 4m intervals
vertically.
Maintenance
All components and their parts should be regularly
inspected to identify damage, particularly to welds. Lost
or broken parts should be replaced, and any tubing with
indentation greater than 5mm should not be used.
Adjustable leg threads should be cleaned and lightly
lubricated to keep them free running.

From this stage on you will require the guardrail pack
for platform heights up to 1.7m
1.7m platform height with added guardrails
Stage 2: Base Pack, 2m Extension
Pack & Guardrail Pack
(for heights up to 3.7m)
CHECK NOW if ground is uneven t adjustable legs.
5Fitting Adjustable Legs
Turn Base Unit upside
down so wheels are facing
upwards as shown. Use a
19mm AF spanner to loosen
bolt and remove fixed castor.
Connect legs to castors.
Insert adjustable legs into
tubes, once complete
reverse base frame with
wheels being on floor. Adjust
legs to produce a level
structure. We recommend
that two persons are
required, to ease the
erection process.
Assembly
6Follow the Base Unit procedure, place Horizontal
Brace on bottom rung. Ensure structure is level before
tower system. Use adjustable legs to level. Now fit Spring
Interlock clips (supplied in Guardrail Pack). Assemble the
4 spring locking clips as shown, expand spring over end
and slide down into hole of tube.
7Insert 2 m (8 rung) Lift Frame in Base Frame, ensure
the interlock clips are engaged.

shown. Ensure claws are locked
into position. To unlock press
trigger and lift.
9Attach one stabiliser to each corner of the tower.
Loosen clamp and place around vertical tube, tighten
using handle. Refer to Stabiliser Section for positioning
diagrams. To attach one stabiliser to each corner of
the tower loosen clamp and place around vertical tube,
tighten using handle.

Assembly
During assembly a Temporary Guardrail will be employed.
10 Position Trapdoor Deck on 8th rung. Ensure windlocks
on both sides are locked (see Fig 3). Ascend the tower
through the trap door of the platform.
All components must be passed through the trap door
or be lifted well within the footprint of the tower.
Temporary Horizontal Guardrails must be positioned 4
rungs up from the platform during building.
Assembly
Stage 3
11 Fit temporary Guardrails. Locate Guardrail Frames
and Guardrails. Ensure the interlock clips are engaged.
Bracing pattern should follow a simple zig-zag shape (see
insert).
12 Ensure Intermediate Guardrails are positioned onto
the upright above the horizontal tube, with the claws
locked outwards as shown. Then move the platform and
temporary Guardrails down 2 rungs.
12 13
Assembly
13 Move other platform to the top rung of the 2m
Extension Frame. Ensure all Windlocks are locked.
14 Position upper Guardrails. Now fit toeboards correctly,
ensuring there are no gaps large enough for objects to fall
through and that the trap door can open and close with
ease. (see Toeboard section).
Your Tower is now complete
and is ready to use.
For increased heights refer to
quantity schedule for additional
packs, erect as described in
stage 2.
To dismantle see
dismantling on page 16.

5.8m Platform Height: Add 2m Extension
Pack And Use Medium (SP10) Stabilisers
15 For the 5.8m height 2 further 8 Rung Frames will be
required plus additional Diagonal and Horizontal Braces,
and a further Trapdoor Platform. Build as shown in
stages 11 to 14, taking paticular care to ensure that you
are fully protected by Guardrails on a Platform during as-
sembly.
Should the platforms or braces obstruct on any one
level, simply re-position one of these components by
one rung to suit.
Dismantling
The dismantling procedure should follow steps 1 through
to 14 in the reverse order, but taking particular care with
the gradual removal of Guardrails and Platforms. You
should ensure that you are standing in a safe position and
protected by Temporary Guardrailing, ensuring that no
Diagonal Braces or Stabilisers are prematurely released.
1Remove Toeboards and upper Guardrails.
2Go down to lower platform, remove upper platform.
3Move lower platform and Guardrails up two rungs, so
that you can handle the components above without
over-reaching.
4From the upper platform, remove Guardrail Frames and
their Guardrails.
5Remove remaining platforms, 8 Rung Frames, upper
Guardrails and Diagonals.

Lower Height Setting
Platform Height = 1.7m
Working Height = 3.7m
Packs Required
1 × Base Pack
1 × Guardrail Pack
2 × Small Stabiliser Packs (if used externally) For internal
use stabilisers are not required if horizontal forces are
less than 20kg.
Fitting Toeboards
Start with the End Boards which have red plastic clips.
There are two slots depending on which side you posi-
tion the diagonal brace. Clip into correct slots, as shown,
ensuring that no large objects can fall through and that
the trap door can open with ease.
17

Stabilisers
Attach one stabiliser to each corner of tower at approx. 45
degrees. The bottom clamp should be fitted as low as
possible, refer to the diagram below. Ensure that all 4
rubber feet are in contact with the ground and that the
clamps are secured.
Position stabilisers as shown in diagrams.
When using the medium stabilisers, always extend the
telescopic legs to their maximum position and lock into
position with the interlock clip.
When moving tower lock each telescopic leg just clear of
the ground, unlock castors ensuring area is firm and clear
of all obstructions both on the ground and above. After
moving check all castors are firmly on the ground and
locked, and that the tower is vertical. Re-position stabilis-
ers as above.
