ANL-2
12 Manual del Usuario / DR 500 passive series / User’s Manual
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, the back
bottom eyebolt points can be used to provide
vertical orientation.
The ANL-2 set is an optional set of three
eyebolts and three carabiners. (Dimensions are in
milimetres).
Flying with eyebolts
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
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.
The following illustrations show different views
on eyebolt flying for a single box. The length of the
back cables or chains determines the vertical
angle of the box.
