3.6 Ground-stacked Mid/High
Enclosures
Ensure that the (inverted) top rigging frame is placed
securely on the ground or stage. Secure the mid/high
stack to prevent slippage!
3.7 Pick Points for Flying
COHEDRA
® Mid/high Enclosures
Use only the top rigging frame's shackles to attach
motors, chain hoists and straps. Insert them into
the eyelets in the centre rail designed to accept
shackles!
Never use the round pole on the top rigging frame
to attach shackles or mount motors! This pole is
used only for guiding and securing cables.
Use only the bottom rigging frame to curve the array.
Clear the area immediately below arrays of people
before raising or lowering loads.
Lift and lower flown mid/high enclosures smoothly,
avoiding abrupt stops or jerky motions.
Secure the flown mid/high array in place with straps
so that it remains immovable, for example, despite
gusts of wind. Use the eyelets in the bottom rigging
frame to affix straps.
