Tower safety
Never overload the tower. The tower’s maximum
working load is 150kg on the platform. Only one
person is allowed on the platform, along with tools
and materials.
Never lean anything against the tower.
Never use if for jobs that excert repetative or
excessive force. Lateral force over 198N -
equivalent to a 20kg weight - make it unstable even
when fitted with stabilisers or balast. This section
includes a table (a) to indicate what level of lateral
force is exerted by typical jobs. Those jobs likley
to exert excessive sideways force should not be
carried out on this tower, whilst those likely to
excert moderate sideways force should be carried
out with due care.
Never use boxes, steps etc to gain extra height.
Never reach too far out to one side.
If the tower is to be repositioned on a higher step,
DO NOT attempt to move it as a complete
assembly. Always dismantle it and rebuild at the
new location.
General Safety
This tower is intended only for indoor use, and must
not be positioned where it could be subjected to
wind loads. Ensure that the site or stairwell where
it is erected does not induce any funneling or
concentrating effect of the wind, or where opening
of doors could introduce sudden wind loads.
Ensure that you are not contravening any health
and safety law (blocking a fire exit for example)
before proceeding to construct the tower on the
stairwell.

Assembly Procedure
1
Push base plates onto adjustable leg. Then insert
base plate/adjustabile leg assembly into 2
standard frames. Ensure they are equally they are
equaly extended so that they stand level. These will
now be reffered to as base frames.
2Fit an aditional frame to one of the base frames
and engage the interlock clips. Place the base
frame, fitted with an extra frame, on the lower stair
and the singular base frame on the upper stair,
allowing the correct distance between the frames for
the platform to fit (1.3 metres).

Assembly Procedure
3Link these two frames with two horizontal and two
diagonal braces as shown in the illustration, to
form the tower base - start by clipping the horizontal
braces to the frame uprights.
4Fit the platform to the top rungs of the two end
frames. Make sure all four platform end hooks are
in contact with the top rungs, then secure in place by
engaging the hook latches (see illustration). Fit a
standard frame to the top end of the frame that is at
the lower step, secureing it in place with the interlock
clips. Fit the gate frame to the top of the frame that is
resting on the uper step. Make sure that the access
bar is positioned so that it opens in towers the tower.

Assembly Procedure
5Now attach the four guard rails (see illustration)
ensuring that the claws face outward. To
complete the tower, the toeboards must be fitted on
all four sides of the platform.
6Now refer to the stabilisation guide (Page 7) and
table to use the correct means of stabilising the
tower.
The manufacturer strongly recomends that ballast is
used in all applications in addition to any method of
stabilisation used. Please contact your supplier ro
hire shop for details.
If stabiliser(s) are required, they must be fitted to
the corner(s) of the end frame on the lower step,
angled at 45 degrees. The clamps should be fitted to
the clear sections of the frame uprights, away from
the interlock clips and rungs. Once fitted they must
have a minimum sideways extension of 650mm and
also reach down the stairs for a minimum distance
of 650mm. Ensure that the rubber foot is firmly
in contact with the ground, and that the stabiliser
clamps ae securely tightened.

Stabilisation guide
Refer to the table below for the correct method(s) of
stabilising the tower for the stairwell in which you intend to
erect it:
Position of tower in
Stairwell
Staircase clear Width
0.8 to
1.4m
1.4 to
2.0m
2.0m or
greater
Free standing (No walls on
either side of staircase) A A A or C
Up against a wall on one
side of the staircase A or D A, B or D A, B or D
Mid-way between walls
on each side of staircase A or D A or D A or C
For additional stability more than one stabilisation method
may be used. The manufacturer strongly recomends
that ballast be used in all applications in addition to the
alternative methods indicated by this guide.
Methods of stabilisation:
AStrongly recomended: The tower is fitted with 150kg of
ballast uniformly spread along the bottom rung of
each base frame (i.e. 75kg at each end). Please contact
your supplier or hire shop for details.
BThe tower is positioned up against a wall on one side,
and a stabiliser is fitted on the other, to the end frame
on the lower step. The stabiliser must have a minimum
sideways extension of 650mm, and reach down the stairs
for a minimum distance of 650mm.
CThe tower is fitted with a stabiliser on both sides, each
with a minimum sideways extension of 650mm, and
reaching down the stairs for a minimum distance of
650mm. Additional stabiliser available from your supplier or
hire shop.
DThe tower is fixed solidly to a wall on one side with ties.
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 secure to either the face of a solid structure or by
means of anchorages. Tying in with rope or non rigid
members is not acceptable.
