    Now that's the way to pack truss.

    Interesting. I would be concerned about the load limits if it's THAT portable. I suppose it's more of a light duty application. I would be afraid to hang a bunch of Mac 2k's on truss that folds.

    The truss is up and the lights are hung... nobody move! :shifty:

    It doesn't fold. It is welded in the form of a V. I'll have loading data on Monday and post it.

    I just found out that a ten foot span has a center point load capacity of 195#. No, you're not going to hand a bunch of Mac's from it but you could probably fill it with LED pars.

    The picture also doesnt have fixtures hung from it so really all its showing is how well the car can store a full set of truss in its trunk.

    I'm having a bit of a brain crap but I think I remember # means kilograms if so a Mac 2k wash weighs 34 kg and therefore 4 lights on the piece of truss would be cake and if the necessary cable isn't real heavy you could even get a 5th light and still be under weight.

    This also hinges on me being right when I assume that you're talking center point load you're doing so because that's the point that will cause the piece of truss to bend the most and the amount of the bend is what will eventually cause failure in the truss. Weight not in the center of the truss would cause the truss to bend less and therefore not be as detrimental to the integrity of the truss.

    # is lbs. 2.2 lbs per kilogram. The other number we need here is Uniform Distributed Load.

    "#" means pound, hogsteak, (~0.45 kg). By comparison, for the company's Model 109-T10 truss, which I suspect is the closest non-V variety: a 10' length has a Max. UDL of 649# and a Max. Point load of 396#.

    Industry-standard 12"x12" x 10' light-duty box truss (plated), has a Max. UDL of 4460# and a center point load of 2231. Tomcat - Light Duty Truss.

    So this product is really just designed to do what it shows in the picture... which is to use for things like show booths and maybe a small DJ setup. You can't hang more than a few lightweight fixtures on it. So it's not something that Derek needs at work but there are people out there that would love a lightweight solution.

    :lol::mrgreen::clap:
    AWESOME!!!

    Mmm steak, I suppose truss like this would be great for your mobile DJs though, I presume that's what the product is aimed at.

    I can see a lot of applications for this kind of stuff. Not necessarily for straight theater or rigging Mac2K, but other stuff.

    Bill, do they offer base plates?

    Len,

    All of the standard 109 accessories will interface with the V-Truss.

    Is see lots of applications in theatre for a product like the V-Truss. Set construction is one. Flying soft goods is another off the top of my head.

    I believe the primary target market is the trade show industry but I'm confident Imagineering will create quite a demand for a product such as this.

    One other note: Rated loads for truss are at least listed at a factor of 3.

    Care to elaborate, I'm sure that makes sense to someone that knows what you're talking about, but that doesn't really make sense to me.

    Pieces of gear that are used in load situations are given a rated load.

    Let's use chain as an example. If a chain is rated for 1000 pounds of load, a factor of three means the chain actually fails when a load of 3000 pounds is applied. The factor is different for catagories of equipment and can be as much as 10 to 1.

    Oh, and there is the converse. Static loads (like a par can) work on rated loads, but moving loads actually require higher ratings. So, a 75 pound mover needs to be looked at as if it were a much larger static load. In other words, the 75 pound mover could exceed the design capacity of a truss rated at 100 pounds, even if the break point was 300 pounds!

    Still, this product looks very interesting as long as all factors are kept in mind.

    everything has its place and application. As Bill says you could hang a number of aluminium parcans of this truss, in a small church hall, hotel ballroom etc. it has its place. After all there are many venues where moving lights and the truss required to fly them can't fit. The trick is knowing what works in each application and making it look like a $1 million.

    And for those theatres that don't have a full warehouse worth of storage to put their gear away into, I imagine this is really nice for those applications where space is tight. To each product, it's own purpose, especially for people touring the country out of the back of their car or truck, should they be putting on a magic show or giving presentations. I've had people show up with eight 6' booms in their car plus as many S4's as they can cram into it, and somewhere up front, they have a place to sit while they drive.
