Compact CDR 210 C Subwoofers
• No more than six CDR 210 C subwoofers may be
flown in stacked array with the standard rigging
frame.
Warning: Flying more than six subwoofers in stacked
array voids the safety standards authority TÜV’s
certification!
CDR 210 C subwoofers and CDR 108 C mid/high
units may also be flown together on one rigging frame.
Refer to table 2 to determine flown loads. The sum
of the weights of CDR 210 C subwoofers and
COHEDRA
® Compact mid/high enclosures plus the
weight of the rigging frames equals the total load.
Note: Ensure that you add the weights of chain
hoists, motors, cables and further stops to determine
total weight!

2.6 Pick Points for Flying
COHEDRA
® Compact Enclosures
Use only the top rigging frame’s shackles to attach
motors, chain hoists and straps. Shackles are inserted
into the elongated holes in the center rail!
Clear the area below arrays immediately of people
before raising or lowering loads.
Lift and lower flown mid/high enclosures smoothly,
avoiding abrupt stops or jerky motions.
Secure the flown array with straps to prevent it from
moving, for example, in the event of wind.
