4.3 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, 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 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.
4.4 Rigging with AX-TRUSS
The AX-TRUSS rigging hardware has been
designed to fly the cabinets from structure trusses of
50 mm diameter (2 in diameter). The AX-TRUSS base
must be fixed to the upper rear corner of the box by
means of two M10 screws. The screw needed to
attach the AX-TRUSS base to the upper side of the box
is the same that comes with the box on that position.
The screw to be inserted on the rear side of the box is
a special one that is provided with the AX-TRUSS
accessory.
AX-TRUSS allows for several vertical angles
from +10º to -35º. The vertical angle is set up by
inserting a highly resistant quick release pin into the
holes in the AX-TRUSS base.
