Page 32/67 GEO T RIGGING PROCEDURE
4.4.8 Positioning the cluster
• Adjust the overall height and aiming angle of the array by adjusting the front and rear motor
hoists accordingly. Note that the accuracy of the angle and height of the array are critical and the
appropriate measurement tools are necessary to achieve this (see the appendix for a
recommended list of installation tools).
• Install a secondary safety steel between the Kelping Beam and a suitable point in the supporting
structure.
IMPORTANT
The requirements for secondary safety systems vary with territories. However, the
secondary safety steel MUST have a SWL equivalent to or greater than that of the rigging
system.
4.4.9 De-rigging and loading out
Taking the system down is just a case of doing
the reverse procedure to flying the array.
However, there are some important factors to
consider.
• Lower the array running the
two motor hoists
simultaneously until the
bottom cabinet is just off the
floor.
• Run the rear motor hoist
down until there is no
tension on the GEO T
kelping chain and no
compression on the system.
• Disconnect the GEO T
kelping chain from the GEO
T bottom bumper and
remove the bottom bumper
from the array. (You may
have to remove the T2815’s
first)
• Run the rear motor hoist
back up until the GEO T
kelping beam is level and
the array hangs vertically.
• Link cables must be
disconnected and stowed
away in the recesses in the
rear of each cabinet.
• NB : As the system is
lowered it is good practise to
disconnect as many
loudspeaker cables as can
be reached without climbing
the array. This ensures that
10 GEO T 4805 + 2 GEO T 2815 set in compression mode
