Lock Indicator Buttons
The red and yellow buttons are used to show that the lock
mechanisms are engaged or not when erecting the Tower.
At all height settings, the yellow buttons should always be
in the locked position i.e. guard rails should be in place, see
page 8. At the 2 metre height setting, all
yellow and red buttons should be in their locked position.
The locking mechanism of a rung is situated at each end of
the rung immediately below it.
As a rung is lifted, it automatically locks to the frame when
it is in the correct position. When this happens an audible
‘click’ will be heard. At the same time the red or yellow buttons on the rung
immediately below the one being lifted will move to the locked position, see the
example shown right.
Red buttons
The red buttons on the rungs are used to release the locking mechanism during the
time the Tower is being collapsed. There is a red release-button located near
each end of the rungs labelled RUNG 4, RUNG 5, RUNG 6 and RUNG 7. When a
button is activated by sliding it away from the end of the rung, the locking pin at this
position is retracted which allows the rung immediately above (and any rungs and
or structures above this) to move downwards.
Yellow buttons
The yellow buttons act in the same way as the red buttons and are used during the
time the Tower is being collapsed. The yellow release-buttons are located at
each end of RUNG 2 and RUNG 3. These buttons allow the erected safety cage to
be collapsed.
Castors/Stabalisers
A stabiliser leg is an integral part of each castor. In addition to providing a larger
more stabilized foot print, the stabilisers are used to allow the Tower to be used on
an uneven surfaces.
The stabiliser can be rotated through 270 degrees.
It can be locked in one of five positions set at 45
degree intervals.
The castors and adjustable stabiliser legs are
supplied as a single item.
