RIGGING SYSTEM
Warning
Due to the numerous images needed to
explain the aero 20A array system setup, this
manual can´t offer all the necessary information to
rig the DAS Audio system. In this document only
we reflect the safety precautions and a summary
of the elements.
To log in to the complete information, please
consult Rigging Manual, which you will find on
the web page.
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
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 D.A.S. Audio
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 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).
Accessories
aero 20A systems are rigged with the
accessories AX-AERO20, AX-Combo2040 and PickUp
AX-AERO20 (if you need another lift motor).
The platform PL-20S allows the transport of four
units.
Consult the Rigging Manual for more
information about the accessories.
The metal parts are made of steel, covered
with zinc and painting in black, with high
resistency screws which act to reinforce the
stacking and the rigging.
Next, we name the accessories with images.
Manual del Usuario / aero 20A / User’s Manual
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 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 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 D.A.S. Audio
are the user´s responsibility. Use at your own risk.
