January 11, 2021How to hang lighting truss from the ceiling? A question we’re asked by our partners many times.
2020 has been a challenging year for the Entertainment industry. While concerts and festivals are being canceled, we are looking to permanent locations that are quickly converted to “Insta” broadcasting studios. You see them everywhere, your local house of worship and in the boardroom.
This post will break down the fundamentals of how to hang lighting truss. The rigging that is recommended and accessories you could use for hanging a lighting truss from a ceiling.
We think it would be wise to start by defining the task of how to hang lighting truss, with a few questions to ask yourself.
Whats my pick point ? When we say “pick point” we mean that you need to first look up and see what kind of structure you want to hang your lighting truss on. Is the structure made of steel, are you in a commercial unit? Or do you need to drill studs into concrete and create a pick point.
These variants will have an effect on how much weight you should put on your lighting truss.
What am I planning on hanging on the truss ? Whether it’s Led stage lights , professional speakers or LED video wall panels. You will need to calculate the max weight you’re planning to hang on the lighting truss.
Lighting truss usually have deflection charts that are certified by TUV. These charts adhere to specific trusses and manufacturers and tell you how many points you would need to hang your lighting truss off of , based on the model of lighting truss you’ve purchased and weight planned to be hung off it.
Bellow is an example of a deflection chart for GTR Truss G34P series of conical lighting truss
So you can see that, with the above specific truss, if you have a span of 20 ft GTR G34P lighting truss hung over 2 pick points. You will be able to hang a total of 4550 lbs divided every ft by 231lb. I decided to hang something in the middle? The max load would be 2277 lb and the bend/deflection would be 1.1 inches. Which is the maximum safe allowed deflection for this lighting truss at this specific span length.
Another important thing we would like you to know is the recommended ways to choke the truss when trying to create a connection to the pick point.

Many Manufacturers also provide lighting truss accessories
