Fly mode array assembling and hoisting
The numbers in the text below, correspond with the LR24 loudspeaker overview pictured earlier.
Shown on the right depicts
array building in Fly mode
style. Shown with 2 hoists, 1x
GRD24B and 8x LR24
cabinets.
Start removing the
PRRGL24TOP plateaus.
Attach the GRD24B to the first
cabinet on the PRRGL24 pack
(A). Keep all red pins in their
parking slots. Pull the angle
setting pins (4) out and set the
correct angles using the Fly
slot in the angle arm (5). These
angles are determined by the
Alcons Ribbon Calculator™
simulation program. Hoist the
first pack from the pre-rig (B).
Connect the necessary cabling
to the signal input/ link (6)
connectors. Use a sling from
the grid for a tension free cable
hang. Set the angles of the
second pack and place it under
the raised array and make a
connection with both front
couplers (2) (C). Connect the second set of cabling. Lower the hoists, and/ or pull the pre-rig backwards to close the rear opening between the cabinets. Then
the rear connection of the angle arm(5) to the bottom cabinet pin (8) can be made (D). Raise the whole array and angle it to the desired positions.
Use slow speed or speed-controllable chain hoists. Avoid any form of excessive dynamic loading to the array
assembly
