RIGGING SYSTEM
Warnings
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 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 DAS. 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 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 DAS Audio are the user's responsibility. Use at
your own risk.
Description
DAS Audio
AERO-12A
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 guides are assembled to each of
the structures, allow for stacking or flying of boxes.
Splay angles can be changed from 0º to 3º in 0.5º
increments and from 3º to 10º in 1º increments.
