Ceiling Installation (continued)
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 persons should work together, one person adding weights and one person tending
to the line to see if the ceiling assembly can be lifted from the floor.
b. Check the ceiling assembly counter balance early and often
(after adding each increment of one hundred pounds).
4. Using the rigging system, lift the ceiling panels from the stage
surface and apply about 100 lb (45 kg) of tension to each
lead-set cable (to set each cable).
5. Keeping the ceiling assembly horizontal,
lift it 4' to 5' (1219 to 1524 mm) from the floor.

Make sure that all rigging and rigging hardware
is capable of lifting the ceiling panel component

Always comply with local codes and regulations.
Make sure that all fasteners
are tight before adding any
weight to the arbor.
