For flying boxes (flown) boxes and defining the
splay angle, the pins must be inserted in the slot of
guide 2, whereas for stacking (stacked), the pin
goes through the top whole of the guide:
All units in a column will be flown from the
flying grid (bumper, frame), which allows for
flying both the and , as well as
providing several vertical aiming angles for the top
box (
only). The grid uses either one or two
pickup points, to allow for quick and easy vertical
aiming.
The pickup points will be used in conjunction
with electric hoists (motors) for load lifting. One or
two hoists shall be used, depending on array size.
Small 4 to 6 unit columns may use a single hoist.
Hoists used will be 1/2 ton when using two per
cluster, or 1 ton when using a single one. In either
case the user needs to check that the weight of
the complete array is lower than the load capacity
of the hoist.
If two hoists are used, the load capacity will be
given by the weight of the cluster divided by two:
Hoist load capacity> cluster weight/2
It must be noted that two hoists will be
required for configurations that require a large
number of units and/or need to tilt the cluster.

The G1A front guide provides a solid
connection to the box and whatever is on top of it,
while the G2A back guide determines the vertical
splay angle (whether stacked or flown), as a
function of the hole where the pin gets inserted.
To ease the setting of the G2A guide in the
corresponding hole in the top box, each hole is
labelled with an associated angle, both for stacked
and flown applications.
To fix the guides to the holes, highly resistant 6
mm quick release pins are used (AISI 4130 steel
alloy) with ball safety lock:
