Fly The Ceiling Assembly
1. Clean all debris from the ceiling panels and remove any tools
resting on the ceiling panels.
2. Get the weight of the ceiling assembly and the
arbor weight calculation from the installation drawings.
3. Start adding the weights to the arbor.
a. Three or more people should
work together, adding weights
and tending to the line to see
if the ceiling assembly can be
liftedfromtheoor.
b. Check the ceiling assembly
counter balance early and often
(after adding each increment).
4. Using the rigging system,
lift the ceiling panels from the
stage surface and apply around
100 lb (45 kg) of tension to
each lead-set cable.
5. Keeping the ceiling assembly
horizontal, lift it
4' to 5' (1219 to 1524 mm)
fromtheoor.

2. With a box level, check the along the length of the ceiling panel row and make sure that it is
straight and level.
a. Turn the adjustment screw on the hanger arms to correct any non-straight or out-of-level conditions.
b. Rotate the ceiling assembly as little as possible when making adjustments.
3. With one person standing and observing at the end of the ceiling panel row:
a. Rotate the ceiling panel row until the bottom surface faces downstage.
b. Then, rotate the ceiling panel row until the bottom surface faces upstage.
c. Any ceiling panel row bowing in either vertical position indicates that further leveling
is required.
