D.A.S. Audio ST Series - Manual (Page 18)

2.1 Introduction
Models ST-1510 and ST-182 feature internal steel
angles, with 4 mounting threads each, so that 4 eyebolt
flying points are available for each angle. 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 fixed installations where the
boxes are permanently flown.
The illustration shows the internal metal hardware
of an enclosure with eyebolt flying only.
In addition to the eyebolt flying points, the ST-1510
provides two aeronautical-type AncraTracks on the top and
bottom panels and one rear-located short track for vertical
orientation. This system allows fast system flying using two
or four rigging points.
The illustration shows the internal metal hardware
and hanging of an enclosure with eyebolt and track-based
flying.
NOTE : Truss modules and rigging accessories are available
from DAS Audio. Consult your distributor for information.
2.2 Flying with eyebolts
The Allen-head screws must be removed and
replaced by M10 eyebolts on one side of the enclosure. Each
rigging point has 200 Kg (440 lb) working load limit. Then
choose the slings or chains of 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, we can provide vertical orientation
by using the back bottom eyebolt points on the units that
feature them.
The ANL-2 set is an optional set of four eyebolts
and four carabiners. Each ANL-2 eyebolt has a rated working
load of 200 kg. (440 lbs.). Each ANL-2 carabiner has a
working load of 330 kg (726 lbs.). 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 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.
