Safety First
STABILISERS/BALLAST
● Stabilisers or outriggers and ballast weights shall always be tted
when specied.
● The Quantity Schedules show the recommended stabilisation.
In circumstances where there is restricted ground clearance for
stabilisers/outriggers, contact your supplier for advice. Ballast
must be of solid materials (i.e. not water or loose sand) and should
not be positioned to overload individual legs. Ballast should be
secured against accidental removal where practicable, and be
supported on the lowest rung of the bottom frame.
MOVEMENT
● The tower should only be moved by manual effort, and only from
the base.
● When moving the tower, beware of live electrical apparatus,
(particularly overhead) plus wires or moving parts of machinery.
● No person or materials should be on the tower during movement.
● Caution should be exercised when wheeling a tower over rough,
uneven or sloping ground, taking care to unlock and lock castors.
If stabilisers are tted, they should only be lifted a maximum of
25mm above the ground to clear ground obstructions.
● The overall height of the tower when being moved, should not
exceed 2.5 times the minimum base dimensions, or 4 metres
overall height.
● Before use, check that the tower is still correct and complete.
● After every movement of the tower, use a spirit level to check that
it is vertical and level and set the adjustable legs as required.
● Do not move the tower in wind speeds over 7.7 metres per second
(17mph).
