The load capacity, of each lift motor, should 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 D.A.S. Audio are the user's responsibility. Use at your own
risk.
ANL-2
To hang the units, the Allen-head screws must be removed and replaced by M10 eyebolts on one side of
the enclosure. Each rigging point has a 200 kg (440 lb) working load limit.
Then choose the slings or chains of a required load resistance and length, bearing in mind that the length
difference between the front and back slings or chains will determine the vertical orientation. Alternatively, the
back bottom eyebolt points can be used to provide vertical orientation.
The ANL-2 set is an optional set of four eyebolts and four carabiners. (Dimensions are in milimetres).
Each ANL-2 eyebolt has a rated working load of 200 kg. (440 lb). Each ANL-2 carabiner has a working
load of 330 kg (726 lb). If using other hardware, make sure it is rated to handle the required load.
When using eyebolts it is important to bear in mind that the rated working load is only true for a load
applied in the plane of the eye, and is significantly reduced for other angles. The drawing above illustrates the
concept.
The table shows the variation of the working load as a function of the load angle. In the case of the ANL-2
eyebolt, this means that the 200 kg working load becomes 60 kg at 45 degrees. Do not use eyebolt flying if
the load angle is higher than 45 degrees.
Note: As always, when we handle heavy loads, we should wear appropriate clothing and
protective elements such as gloves, safety shoes, etc.
