4.2 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, 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 millimetres)
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.

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.
