2.3 SAFETY FACTORS
breaking load limit and the
maximum safe working load limit (SWLL). In this
case, the breaking load limit of each of the flying
points is 4,000 kg (8,820 lbs) as determined by
destructive testing in independent laboratories. With
a 10:1 safety factor, a total amount of 1,600 kg (3,527
lbs) can be flown from the 4 flying points. Each flying
point has a capacity of 400 kg (882 lbs) with a 10:1
safety factor.
The safety factor is defined as the
coefficient between the
T
The use of two hoists with a load capacity as
expressed on the previous page is mandatory. It
should be kept in mind that at certain moments, the
complete load may be supported by only one of the
hoists.
he maximum number of AERO-38 units
that can be suspended from the AX-AERO48 flying
grid is 20 (with 10:1 safety factor). T
The
maximum limits established by the manufacturer
should never be exceeded.
This is why the load capacity of the individual
hoist must be superior to the weight of the array
column.
NOTE: The rigging systems of the AERO-38 and the
AERO-48 are compatible. Some accessories (AX-
AERO38, AX-AERO48) can be used by both systems.
he maximum
number of AERO-182 units that can be suspended
from the AX-AERO48 flying grid is 16 (10:1).

rotated (clicked) into place will the AC turn on. The
connector can be used as a switch, rotating the
connector to or from the locked position will turn the
unit on or off, respectively. Mute the signal feeding the

units, which will share the same input. The output can
also be used to provide signal for an outboard power
amplifier.
