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 funneling effect.
●
Do not abuse equipment. Damaged or incorrect components
should never be used.
●
Raising and lowering components, tools, and/or materials by
rope should be conducted within the tower base. Ensure that
the safe working load of the supporting decks and the tower
structure is not exceeded.
●
The assembled tower is a working platform and should not be
used as a means of access to other structures.
●
Beware of horizontal forces (e.g. power tools) which could
generate instability. Maximum horizontal force 20kg.
●
The stairway towers featuring an inclined staircase access are for
use with personnel frequently carrying tools and/or materials.
●
Mobile towers are not designed to be suspended - please
refer to your supplier for advice.
Ties
●
Ties should be used when the tower goes beyond its safe height
beyond the limits of the stabilisers/outriggers or if there is a
danger of instability. 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 dia. tube
of the tower should be used. Ideally ties should secure to both
faces of a solid structure or by means of anchorages.
●
The tie frequency may vary depending on the application, but
they should, at a minimum, be at every 4 metres height.
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 indentations greater than 5mm should
be put to one side for manufacture repair. Adjustable leg threads
should be cleaned and lightly lubricated to keep them free running.
