Is there a safe way to hang my truss from ceiling trusses?

I have global triangle sections that I'd like to hang from the ceiling trusses if possible. Is there a safe/legit method?

I'm going to be hanging probably 3 lights per 10 foot section totalling 75 lbs. per section.

I really do not understand what your trying to do. I don't get the "ceiling truss" but its 3am so maybe its me.

I'll take a guess, your referring to Steel I-beams, Steel getters or some type of steel structure supporting the ceiling and/or building. Is there a way to hang your truss off of that? YES! BUT I'm not going to tell you how. That falls under "rigging" so if you really want to do this hire a rigger. And since your asking im guessing you don't know how do please do not try to. Hang anything above peoples head is extremely dangerous and deadly.

So please look at the cost of hiring a rigger and then decided if you really want to do this.

There is, but if you've never done it before, then you shouldn't depend on getting all the info from a post on a chat board. There's a lot of variables, but assuming the steel is 20+ feet off the deck, here's a few general things you'll be required to do.

First, you'll need to get clearance from the venue with an itemized list of what is going to hang, including how long each stick is, and what the electrical and weight load is on it. BTW, how is the cable run going? Dropping off the end of the truss, a pick, a bridge? They'll probably want to see a CAD drawing so you'll need to find someone with Vectorworks Spotlight and you'll also need to know the rigging points for the venue.

Once you have that all known and approved, go to a rigging or production company. Tell them everything. They'll bring out for each stick of truss, 2 - 3 motors (probably 1/4 tons will be all you'll need), burlap, rigging steel, shackles, and a motor distro if their motors are 208. Unless you have to bridle stuff, which is more money, more time, more points, etc. Plus, they'll need feeder to get power from the panel to the distro. And a lift or a rigger to get into the steel and hang the points. All in all, the cost will probably be close to $1500, because a union rigger will want a 4 hour call for the in, plus a 2 hour call for the out, and the production company's rental, etc.

Can you wrap something around them? Motors are a bit overkill for 75lbs. Two chain blocks per section is more than enough. In my area, they can be rented for $20/each.

I can't really recommend anything else without seeing a pic of the beams.

If they're wooden beams, then you really shouldn't be using steel, you should be using a pin and sleeve drilled through the beam. I doubt they'll let you do that.

no offense to Kickascii, but I can't believe you guys are giving any info to this. Len I know you understand the danger of hanging anything overhead. But your giving information, very little but still its info that could help injury of kill someone.

It seems Kickascii hinted to not doing it. But Kickascii if you do PLEASE get a professional rigger to do it.

Nope, I got the hint when someone mentioned liability. Not to mention, I'm only getting paid $500. This is a club/pub that is looking at having me play for a clubnite that told them they should have. I only have 3 10ft. global trusses but I can only go in a straight line because of only having 2 stands.

Is there anybody you can borrow 2 more stands from? I think it would be cool to have 10' behind you at a higher level and then right below that, have the other 10' off either side going out at an angle to the other 2 stands. Stands are pretty cheap. I'd make the purchase. Let us know how it goes.

Stand cheap? The ones I have were about $500 each. Crank stands made by Work. They weigh about 40lbs. a piece...

I'm not sure that is what I call "cheap"... :)

I just picked up some "On Stage" cranks from Hytech gear for around $100 each. They have 150lb capacity and go 12 feet up. They weigh around 31lbs each.

So, yes, these are cheap compared to yours! :lol:

WOW, what a rig for a school event.

#1) I hope their crew were certified riggers.

Anyone want to guess at the power requirements for this rig? Must have been at least 200A@220V. 5 Atomics 8A@220V to start.

I doubt it. No certified rigger would use a sling through the end of a stick like that. It would cause the sling to wear out faster, and it really isn't safe. At least they used a safety. Chances are, the point was off from the truss and they didn't have the correct deck chains to deal with it.

As for the electric, the room is in the northeast corner, and getting a distro from it is fairly easy.

Looking at these pictures, how could you possibly know that?

You can tell N/S/E/W in an indoor photograph?

From the picture, no. But I know from the sign that is the Nequa Valley High School gym in Naperville. I worked a show there with Chris once before. Whoever took the picture (I assume it was Chris) is probably standing near the door to that room.

And yes, standing on a trunk isn't OSHA safe, but I do it all the time. I have to assume that they were doing that because the t-bar and X-spot on the left of that picture were too low to lower the rest of the truss to a more comfortable working height. Likely someone forgot to run a cable somewhere and didn't realize it until the t-bars were hung.
