RIGGING SYSTEM
Warning
This manual contains needed information for
flying D.A.S. 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 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 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.
Product improvement by means of research
and development is on going at D.A.S.
Specifications are subject to change without
notice.
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 142 Kg
(7:1 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 in this respect. It is highly
recommended that you implement an inspection
and 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 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
D.A.S. Audio are the user's responsibility. Use at
your own risk.
Description
D.A.S. Audio
æro
8A
line array systems, include
2 rigging structures on each side of the box.
Manufactured from zinc plated steel they are
painted black and are affixed to an internal plate
with special crop resistant screws. Two special
stainless steel cam links are assembled to each of
the structures, allow for stacking or flying of boxes.
Splay angles can be changed from 0º to 10º in 1º
increments.
