MiTOWER Components
1. Guardrail Brace Panel
Claws are tted to the guardrail brace panels and each has an automatic
locking jaw which is released by simply moving the jaw’s trigger. The claw
must only be attached to the frame with the opening facing outward.
Attachment with the jaw’s opening facing inward will not fully protect
the user if lent upon and may cause serious injury or death. Always
ensure that each claw is positively locked in position before using your
MiTOWER.
5. Platform with built in Component Hangers
To enable one man to erect MiTOWER, each hatch platform is tted
with four component hangers which are stowed (two either side) within
the platform’s frame. The hangers can be extended when needed and
retracted when not. To extend and lock a hanger, take a hold of the
hanger stop end and pull from the frame. Once the stop rivet is clear of
the slot, turn the hanger 45 degrees anticlockwise then gently slide back
in until it stops. To retract the hanger, simply reverse the procedure.
4. Wind-lock Catch
The wind-lock catch is a drop down jaw tted to the side of the hatch
platform’s mounting hook and prevents the platform from lifting in
windy conditions. It is attached to the horizontal tube of the frame.
To disengage, simply lift and hold the jaw as you raise the platform
clear.
6. Adjustable Leg and Castor
The adjustable leg and castor allows for accurate positioning of your
MiTOWER in relation to your workplace. The leg can be extended or
retracted to allow for levelling and the brake must be applied to prevent
movement.
2. Frame Clips
The frame clip’s pin locates into a retaining hole in the frames to lock
tower sections together when placed one on top of the other. The pin is
locked in place by a red tab to ensure that it remains in place.
From the disengaged position, pivot the pin / tab to bring the pin
horizontal. Insert the pin fully through the retaining hole with its tail
pointing down. Next ip the tab vertically to lock the pin in place.
Removal is simply a reversal of the tting sequence.
3. Stabiliser Coupler Clamp
The coupler clamps are used to secure the stabilisers to MiTOWER’s
vertical tubing. With the clamp jaw open, offer it to the tube. Bring the
jaw around the tube and set the buckle on to the hook, then close the
clamp arm to lock the stabiliser in position. A similar clamp is tted to
the stabiliser extension leg.

10 Before You Start
Preparation
The oor area must be clear of any obstructions including materials and debris. Check
that you have all the components necessary to construct the tower height you require.
Check also each component for condition and correct function. If any part is missing or
damaged/not working correctly it must be replaced before assembling the tower. The
use of a combination of tower parts of different brands/manufacturers is not permitted
Towers for professional use must be inspected annually for any defects by an expert.
Method of construction
The method of construction has been developed to reduce the risk of an erector
falling from a tower during construction. The erector must sit on the platform
with legs through the hatch and feet on the frame rungs when attaching guardrail
brace panels above the platform. This ensures the erector is always protected by a
set of guardrail brace panels.
Assembly Guide
These instructions must always be made available to the user. If replacement copies
are required, please contact your supplier.
Damaged Components
Regularly inspect all components for damage. Damaged components must be
quarantined so that they cannot be used. Where safe to do so, the component can be
repaired but only by a qualied repairer. If in doubt contact your supplier for advice.
Dismantling Your MiTOWER
MiTOWER is easily dismantled by simply reversing the erection procedure. Make
sure that the component hangers are evenly loaded to ensure your MiTOWER
remains balanced. You must, however, be protected by guardrail brace panels when
standing on any platform and ensure that you use the method of construction when
removing guardrail brace panels.
Tying In
You should consider tying in the tower to add to stability, but this may only be
carried out by a suitably trained person.

11

Getting Started
Getting Started
MiTOWER requires only one person to assemble and dismantle it. Your MiTOWER is
supplied with uniform 1m high 4 rung frames which can be used at any stage of the
assembly. During erection, the frames may be connected together to create 2m high
frames which makes assembly both quicker and easier.
Moving Your MiTOWER
When your MiTOWER needs to be moved a small distance to enable you to continue
your task, this can be achieved provided the stabilisers can remain in pattern and all
tools, materials and personnel are removed from the tower.
You will need to raise the stabilisers so that they are no more than 25mm above the
oor and properly locked. However, if the stabilisers have to be repositioned and this
reduces the footprint, your MiTOWER must be reduced in height to 2m.
You must only move MiTOWER by manual effort at a slow pace and only after fully
assessing the risk. Once moved, always check MiTOWER before using.
If MiTOWER is to be moved to a new location, a new level or over rough terrain, it
must be fully dismantled and rebuilt at the new location. Hoisting or suspending the
MiTOWER is not permitted.
Stabilisers Positioning
Stabilisers are supplied and must be used for all MiTOWER heights.
For maximum effect arrange the stabilisers by positioning at an angle of 45 degrees to
give a footprint as close to square as possible, as shown in g.1.
If the tower is to be positioned against a wall, the stabiliser footprint can be altered
as shown in g.2 but only where the height of the wall is a minimum of two thirds the
height of the top working platform.
Ensure that all four stabilisers’ feet are in contact with the ground and that the ground
can support the weight of the tower and stabilisers.

12 MiTOWER 2m - Assembly
Fully insert the adjustable legs with
castors into two frames, turning the leg’s
height adjustment collar to bring each leg
25mm from the lowest position.
Step 1
Construct two sets of conjoined frames, these will give you
two 2m sections and will speed up the erection process.
Release the frame clips on one four rung frame and t
it on to a second four rung frame. Apply the frame clips
and ensure they are correctly locked. Repeat this with
the second set. Fit one set of conjoined frames to a base
frame and apply the frame clips. Repeat this with the
second set.
Next, attach one guardrail brace panel with its upper
jaw positioned beneath the eighth frame rung. It must
be tted on the opposite side to the rst guardrail brace
panel to ensure stability. Ensure all claws are facing
outward and correctly locked on to the frame tube.
Step 3
Step 4
Attach a guardrail brace panel to the
vertical tube of one frame with the upper
claw positioned above the fourth rung
and with all claws facing outward. Make
sure the claws are correctly locked on to
the frame tube. Now attach the second
frame to the guardrail brace panel to
create the base frame assembly. Lock all
four castors and using a spirit level as a
guide, adjust each leg to bring the base
square and level.
Step 2

12
MiTOWER 2m - Assembly
Stand inside the tower and t a platform on to the eighth
rung, making sure that the wind-lock catches engage.
Step 5
Fit a stabiliser to each corner of the tower. Position the
lower horizontal stabiliser coupler clamp just above
the frame’s second rung, then secure the top stabiliser
coupler clamp just above the frame’s fth rung. Adjust
the stabilisers so that you create as square a footprint
as possible. Adjust each stabiliser’s length so that they
are in contact with the ground. Make sure all coupler
clamps are correctly secured. Extend and lock the
four component hangers located on either side of the
platform.
Step 6
Place two guardrail brace panels on to one set of
hangers, and the toe boards in to the opposite set.
Enter the tower framework and climb the frame rungs
until you are half way through the platform’s trap door.
Now manoeuvre yourself so that you are sitting on the
platform, with your legs through the trap door and your
feet on the frame rungs. From this position, you should
take each of the guardrail brace panels, one at a time,
and attach so that the upper jaws are positioned above
the twelfth rung.
Step 7
With both panels in position, you may access
the platform. Unfold the toe board set and
position so that they sit on to the outer edge of
the platform. Finally, retract all hangers and the
tower is now complete and ready to use.
Step 8

14 MiTOWER 3m - Assembly
Replicate steps 1 & 2 from 2m assembly.
Fit a single 1m frame to a base frame and
apply the frame clips. Fit a second 1m frame
to the other base frame.
Step 1
Fit a platform on to the fourth rung,
making sure that the wind-lock catches
engage. Next, attach a pair of guardrail
brace panels opposite each other with
their upper jaws positioned above the
eighth frame rung. Ensure all claws are
facing outward and correctly locked on
to the frame tube.
Step 2
Fit a stabiliser to each corner of the tower.
Position the lower horizontal stabiliser
coupler clamp just above the frame’s second
rung, and then secure the top stabiliser
coupler clamp just above the frame’s fth
rung. Adjust the stabilisers so that you create
as square a footprint as possible. Adjust each
stabiliser’s length so that they are in contact
with the ground. Make sure all coupler
clamps are correctly secured.
Step 3
Construct two sets of conjoined frames,
these will give you two 2m sections. Release
the frame clips on one four rung frame and
t it on to a second four rung frame. Apply
the frame clips and ensure they are correctly
locked. Repeat this with the second set.
Place the conjoined frames one at each end
of the tower ready to be tted. Extend and
lock the four component hangers located on
either side of rst platform.
Step 4

MiTOWER 3m - Assembly
Place a guardrail brace panel on to a component
hanger on one side of the platform and a second
platform on the other side. Access the rst
platform and attach the guardrail brace panel
with its upper jaw positioned beneath the twelfth
frame rung. Ensure all claws are facing outward
and correctly locked on to the frame tube. Now
carefully t the second platform on to the twelfth
rung, making sure that the wind-lock catches
engage. Extend and lock the four component
hangers located on either side of the platform.
Descend the tower and from the ground place
two guardrail brace panels onto the hangers on
one side of the second platform and a set of toe
boards on the other side.
Step 5
Access the tower until you are half way through
the second platform’s trap door. Now manoeuvre
yourself so that you are sitting on the platform,
with your legs through the trap door and your
feet on the frame rungs. From this position, you
should take each of the guardrail brace panels,
one at a time, and attach so that the upper jaws
are positioned above the sixteenth rung.
Step 6
With both panels in position, you may access
the platform. Unfold the toe board set and
position so that they sit on to the outer edge of
the platform. Finally, retract all hangers and the
tower is now complete and ready to use.

MiTOWER PLUS Components
1. Guardrail Brace Panel
Claws are tted to the guardrail brace panels and each has an automatic
locking jaw which is released by simply moving the jaw’s trigger. The claw
must only be attached to the frame with the opening facing outward.
Attachment with the jaw’s opening facing inward will not fully protect
the user if lent upon and may cause serious injury or death. Always
ensure that each claw is positively locked in position before using your
MiTOWER PLUS.
5. Platform with built in Component Hangers
To enable one man to erect MiTOWER PLUS, each hatch platform is
tted with four component hangers which are stowed (two either side)
within the platform’s frame. The hangers can be extended when needed
and retracted when not. To extend and lock a hanger, take a hold of the
hanger stop end and pull from the frame. Once the stop rivet is clear of
the slot, turn the hanger 45 degrees anticlockwise then gently slide back
in until it stops. To retract the hanger, simply reverse the procedure.
4. Wind-lock Catch
The wind-lock catch is a drop down jaw tted to the side of the hatch
platform’s mounting hook and prevents the platform from lifting in
windy conditions. It is attached to the horizontal tube of the frame.
To disengage, simply lift and hold the jaw as you raise the platform
clear.
6. Adjustable Leg and Castor
The adjustable leg and castor allows for accurate positioning of your
MiTOWER PLUS in relation to your workplace. The leg can be extended
or retracted to allow for levelling and the brake must be applied to
prevent movement.
2. Frame Clips
The frame clip’s pin locates into a retaining hole in the frames to lock
tower sections together when placed one on top of the other. The pin is
locked in place by a red tab to ensure that it remains in place.
From the disengaged position, pivot the pin / tab to bring the pin
