3.6. Secondary Safety
Four x 45° steel tabs at the front and back corners of the array frame allow for a
secondary point of safety. The secondary rigging point should be independent of the
main rigging point and must be capable of supporting the entire load.
From each safety point on the frame one tonne shackles must be used attached to
wire slings to form an equilateral triangle maintaining the maximum sling angle of
60°. A further two shackles must be used on the other end of the wire slings and then
attached to a load ring, and from there to the secondary safety point in the venue or
tower that the array is suspended from.

3.7. Cable Pick
On the rear of the frame 2 x 10 mm holes are positioned for use with 10 mm eyebolts
as cable picks. When
fl
ying CORA-S these can be utilised for cable strain relief. When
fl
ying CORA/CORA-A array the motor point should be used for strain relief so that the
arrays angle is not compromised.
