3. ASSEMBLING AN ARRAY
3.1TRANSPORTING THE CABINETS
AERO-48 units can be transported by using
the front panel dolly PL-48 or by using the PL-48S steel
dolly which can transport a maximum of 3 AERO-48
stacked in an arc or 4 units stacked vertically.
The Aero-218SUB can be transported on the
rear located casters. Their rectangular shape
facilitates stacking without the use of the rigging
hardware.
3.2 PLANNING/INSPECTION
3.3 ASSEMBLING AN ARRAY “ONE
BY ONE”
When few units are to be used (minimum
systems recommended is 6 units) or when the dolly
platforms cannot be used due to a lack of space, the
enclosures will have to be hung “one by one”. The first
step will to attach the AX-AERO48 grid structure to
the hoists. The chain slings need to be attached to the
structure using the shackles provided with the grid.
Once this has been accomplished, the grid structure
can be placed in a vertical position by lifting the rear
hoist and lowering the front hoist so that the rear of
the grid is on top and the front of the grid at the
bottom, ready to receive the first box.
The next step is to attach the first unit to the
grid by introducing the G1A48 and G2A48 guides in
the receiving points of the grid structure and assuring
them with the six safety pins. The safety pins should
be inserted in the slot of the G2A48. It is very
important to make sure that the pins have been
inserted and locked correctly.

Once the first unit of the array has been
attached to the AX-AERO48, the assembly should be
lifted by way of the rear hoist until the wheels of the
PL-48 dolly platform lift off the ground. From this point
on, the front hoist can be used to lift the box into a
horizontal position.
Before installing the AERO systems it is a
good idea to run a simulation with the AEROWARE
program utilizing the venue dimensions. This way we
can determine the needs that should be met by the
rigging structures such as hoists, cranes, beams,
rigging points, etc. Besides providing weight
information, the program also provides users with
splay angle information, safety pin positions and
coverage predictions.
Inspection is the next step after planning
and acquiring all the necessary parts needed to
elevate the systems. All parts, including the hardware
attached to the enclosure, the safety pins, etc. should
be thoroughly inspected before each use. Units
exhibiting deformations, cracks or any other defect
should be replaced with new units.
It is extremely important to assure that each
and every one of the aforementioned structures is
capable of supporting a superior load than that of the
complete system.
It is important to establish an inspection
routine for the complete rigging system before each
event or installation as well as establishing the
maximum load specifications of the hoists to be used.
Rigging should be carried out by experts
familiar with the way the systems function and their
characteristics.
On occasions, it may be convenient to have
additional tie down points to impede the array from
twisting or swinging.
