BEFORE YOU START
Page 11
PREPARATION
The staircase 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.
3T (THROUGH THE TRAPDOOR) SYSTEM
The 3T method of construction has been developed to reduce the risk of the erector falling from a tower during
construction. To ensure the erector is always protected by a set of guardrails, they will be attached to the frames
whilst the erector sits on the platform with legs through the hatch.
TYING IN
Mi TOWER STAIRS heights outside the scope of this instruction guide can be built using special components and
tying in the Mi TOWER STAIRS structure to add stability. In these instances contact the manufacturer for further
information and guidance.
BALLAST
Where shown in the component list, ballast must be used to stabilise against overturning. Only use solid
materials as ballast (i.e. no loose materials) and position to avoid overloading individual components. Ballast
should be supported by the base of your Mi TOWER STAIRS and securely fastened to prevent removal.
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 Mi TOWER STAIRS
Mi TOWER STAIRS is easily dismantled by simply reversing the erection procedure.
You must, however, be protected by guardrail brace panels when standing on any platform and ensure that you
use the 3T method when removing guardrail brace panels.
