5.3 - Permanent Installations
Any installation (permanent or temporary) must be securely attached to the structure of
the building using chain, steel wire or web straps that are certified and load rated for the
loudspeaker system. Consideration must be taken when determining the loading on the
structure to include loudspeakers and rigging hardware, and the appropriate safety factor
can then be decided upon. If you are in any doubt whatsoever, please contact your
EM Acoustics dealer who will be able to refer you to an experienced rigging company. A
reputable rigging organisation should also be able to advise on legislation regarding safety
factors for suspended systems of this type.
5.4 - Attachment of the FC-159v vertical flying cradle
The FC-159v vertical flying cradle is intended particularly for
touring purposes, hence the extremely quick attachment
method.
To attach the cradle, first release the two ball-lock pins from the
coffin plate on the cradle. Position the cradle over the top or
bottom of the loudspeaker (it can be flown either way up) and
insert the bosses on the bottom of the cradle’s coffin-shaped
plate into the keyholes on the enclosure’s flying plate. Slide the
cradle to the rear of the enclosure until the two ¼” diameter
locking-pin holes line up. Insert the two ball-lock pins into the
holes to lock the cradle in place. IMPORTANT: DO NOT
ATTEMPT TO LIFT THE LOUDSPEAKER WITHOUT BOTH
BALL-LOCK PINS IN PLACE. The point on the top of the flying cradle can be used for
permanent installations or to secure a hook clamp. Ensure that an eyebolt is secured to
the rear point on the MSE-159/MSE-156 (M8 at the rear) or one of the top points (M10 on
top or bottom) to use as a secondary safety. To set the angle of the loudspeaker, there
are standard clamping levers on each side as a primary system however as a secondary,
and to act as a repeatable method for flying, the holes and ball-lock pins allow quick and
easy angle setting in 5-degree increments.
