COSMO Line Array – Instructions for use
16
You may fasten ropes to the pull-back frame's attachment
points to tie the array to truss bars or the like to prevent it
from twisting in the wind.
Note: Use only ropes with suffi
cient tensile strength to
this end. Carabiner or snap hooks are suitable for attaching
ropes.

Heads up: Setting up and tearing down arrays can
be dangerous. People may get hurt and property damaged if
the rig or parts thereof fall, move in unexpected ways, or
are improperly assembled and disassembled. Make sure
quick-release pins, shackles and all other connecting
components in the load line are properly engaged and
secured to prevent them from loosening.
Wear suitable protective headgear,
gloves and footwear when assembling and disassembling
the array.
The following instructions and illustrations apply to both
the CRF-60 and CRF-80.
Note: These instructions for curving an array in fi xed mode
assume that all M/H units have been connected one at a
time to the neighboring cabinet. Easy, safe rigging in fi xed
mode requires at least two people.
1
Attach the C-PPA Pick-point adapter by inserting its two quick-
release pins into the desired positions in the rigging frame's
mounting rail.
2
Connect the chain hoist or other hoisting equipment to the
C-PPA's shackle and lift the rigging frame to a convenient
working height.
Heads up: You may dispense with a secondary
safety device or arrest wire in cases where the attaching
device is intrinsically safe, requires tools to unfasten, and is
secured with a locking mechanism to prevent it from
disengaging on its own. Be sure to heed the applicable local
laws, regulations, and engineering rules.
3
Insert the individual angle pins at the desired position and
remove the fi x pin from the M/H unit's angle plate before
attaching each M/H unit.
