This manual contains needed information for
flying DAS Audio line array systems, description of
the elements and safety precautions. To perform
any operations related to flying the system, read
the present document first, and act on the
warnings and advice given. The goal is to the allow
the user to become familiar with the mechanical
elements required to fly the acoustic system, as
well as the safety measures to be taken during
set-up and tear-down.
Only experienced installers with adequate
knowledge of the equipment and local safety
regulations should fly speaker boxes. It is the
user's responsibility to ensure that the systems to
be flown (including flying accessories) comply with
state and local regulations.
The working load limits in this manual are the
results of tests by independent laboratories. It is
the user's responsibility to stay within safe limits. It
is the user's responsibility to follow and comply
with safety factors, resistance values, periodical
supervisions and warnings given in this manual.
To this date, there is no international standard
regarding the flying of acoustic systems. However,
it is common practice to apply 5:1 safety factors
for enclosures and static elements. For slings and
elements exposed to material fatigue due to
friction and load variation the following ratios must
be met; 5:1 for steel cable slings, 4:1 for steel
chain slings and 7:1 polyester slings. Thus, an
element with a breaking load limit of 1000 kg may
be statically loaded with 200 kg (5:1 safety factor)
and dynamically loaded with 250 Kg (4:1 safety
factor).
When flying a system, the working load must
be lower than the resistance of each individual
flying point in the enclosure, as well as each box.
Hanging hardware should be regularly
inspected and suspect units replaced if in doubt.
This is important to avoid injury and absolutely no
risks should be taken on this respect. It is highly
recommended that you implement an inspection
and maintenance programme on flying elements,
including reports to be filled out by the personnel
that will carry out the inspections. Local
regulations may exist that, in case of accident,
may require you to present evidence of inspection
reports and corrective actions after defects were
found.
Absolutely no risks should be taken with
regards to public safety.
When flying enclosures from ceiling support
structures, extreme care should be taken to assure
the load bearing capabilities of the structures so
that the installation is absolutely safe. Do not fly
enclosures from unsafe structures. Consult a
certified professional if needed.
All flying accessories that are not supplied by
DAS Audio are the user's responsibility. Use at
your own risk.
DAS Audio line array systems ( )
include 2 structures on each side of the box.
These are manufactured from black painted zinc
plated steel; they are affixed to an internal plate
with special crop resistant screws. Two stainless
steel guides assembled on each of the structures:
G1A (front guide) y G2A (back guide), that allow for
stacking or flying of boxes. Angles can be
changed from 0º to 10º in 2.5º increments on the
. On the , three possible angles are
possible that allow for flying from it and stacking
on it; 0º, 2.5º and 5º angles. To lock both guides,
the quick release safety pin supplied (6) must be
used.
