Warning
This manual offers all the necessary
information for flying or stacking EVENT Line
Array series systems of DAS Audio. This
information is illustrated with drawings and
required safety precautions.
To any operations related to flying a
system, read the present document first and
act on the warnings and advice given. The
goal is to 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
teardown.
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
follow and comply with safety factors,
resistance values, periodical supervisions
and warnings given in this manual. Product
improvement by means of research and
development is on going at DAS Audio Group,
S.L. Specifications are subject to change
without notice.
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
clable slings; 4:1 for steel chain slings and 7:1
for 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 142 kg (7:1 safety
factor).
When a system is flying, 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
in this respect. It is highly recommended that
y o u i m p l e m e n t a n i n s p e c t i o n a n d
maintenance program 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 prevent 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.
