What is Lighting Truss

Lighting or Stage Concert Truss allows lighting designers the
freedom to hang LED or Automated fixtures, often called “movers” where ever they
choose. Lighting Truss can be found in Theater, concert, performance arts, or
tradeshows, arenas and stadiums. Anywhere staging equipment is deployed you are
likely to find aluminum lighting truss.

“Sticks” or sections of the truss can be connected together to
create a structure allowing lighting fixtures, video, audio or other staging
equipment to be hung with ease. Lighting Truss comes in several different
lengths and when connected together, create longer spans or different
shapes.

What is Lighting Truss Made of?

The primary materials most commonly used for stage lighting
trusses are Aluminum and Steel.

Aluminum, because of its durability, light weight and ease of
transport, is the optimum choice for use in concert or stage production. Its
weight allows for a quick and easy setup and teardown.

For installations that are permanent such or where high load
ratings are required steel truss is the easy choice. No matter what the project,
always know the load ratings of your truss and deal with
professionals.

Common Sizes

Lighting truss comes in sectional lengths that may be connected
together to create longer spans or different shapes. These truss structures are
used to support lighting, audio and video equipment. The most common truss
lengths are 1 foot, 5, 8 and 10 feet.

Deployment Terms

When Lighting truss is supported overhead it is referred to as
being “flown”. If the truss structure is standing on the ground or is part of a
larger design that is free standing it is most often called “ground supported”
or ground support.

Formats

The most commonly used format for lighting truss are Box truss
and Triangle truss. A valuable format that XSF has designed is Space Saving
truss. Space Saver Truss can transport 100’s of feet more of truss in truck
trailers because of its unique design.

Lighting Truss Applications

The most commonly thought of applications for lighting truss are
concert, stage, theatrical, architectural, trade show and houses of worship. If
you are to dig a little deeper you see that lighting truss is found anywhere
lighting fixtures are deployed.

Manufacturing and Fabrication

Lighting or stage truss is typically fabricated from 2 inch
round aluminum tubes referred to as chords. Truss sections generally consist of
2, 3 or 4 chords. Two chord light truss is often referred to as Ladder Truss,
three chord truss are often referred to as Triangle Truss and four chords would
be a box truss.

The diagonal members or webbing in the truss is generally a
smaller diameter round tube. There are a variety of connections available on the
market that provide an array of different strengths and load ratings.
