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.
