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.
The DAS VANTEC-20A incorporates structures
in each side of the enclosure. Thess ironworks are
made of steel and aluminum and are fixed with
special screws in the wood side of the two systems.
On each one of these structures there is a steel rod
with a special axis screw which allows to stack or rig
the enclosures. The angles vary from 15º to 15º
with each VANTEC-20A. The use of safety pins
isn’t necessary as in other models. This system
allows for easy and safe rigging or stacking.
Flyable vantec series models feature internal
steel angles, so that flying points are available.
Eyebolt flying points are factory sealed with M10
screws, which are replaced with eyebolts on the
flying points as required. Flying with eyebolts is
very economical and safe, and is specially
recommended for installations where the boxes are
permanently fixed.
Manual del Usuario / vantec series / User’s Manual
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 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.
