ACCESSORIES
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.
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).
The load capacity, of each lift motor, should be correspond to a safety factor of 10:1.
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.
