samrennie Posted February 3, 2004 Share Posted February 3, 2004 hello all,Just wondering about the legality of LTM truss being rigged by competent professionals. It is about 20 meters long in a venue that I know. it has 4 points of suspension and 2 large safeties over the majority of the weight. it has about 200kg on it and is completely static, i.e. it is not moving up or down. 1/ can it stay there indefinately 2/ if so does anyone know where the HSE legeslation is for it3/ if not what needs to happen to it to make it nice and legal. if u would post here if u need more info or any ideas cheers Sam Link to comment Share on other sites More sharing options...

Wilf dLampy Posted February 4, 2004 Share Posted February 4, 2004 Just wondering about the legality of LTM truss being rigged by competent professionals.The competent professionals should be able to advise you on this, as they are aware of the methods and materials of attachment used, what they're attached to and how it was rigged. I don't think we should speculate on safety matters like this. Link to comment Share on other sites More sharing options...
samrennie Posted February 4, 2004 Author Share Posted February 4, 2004 yer fair do's, I was just wondering if any one was going to scream ILLEGAL at me at the top of their voice!?!?! I'm not to worried as it was installed by a professional company but my experience is that by using strops it was deemed Temparary and therefore shouldn't be up for more than two weeks without being checked.

j_b Posted February 4, 2004 Share Posted February 4, 2004 FWIW, A venue I've worked in has custom designed brackets holding up the truss, which is definately permanently installed. It still gets inspected annually, as part of the overall venue lifting equipment inspection. Wilf d'Lampy is right though. Get the competant professionals to recommend an inspection period - it will need one, as by what you've said some of those components have a limited lifetime. UV light for example, will cause the polyester slings to deteriorate, if that is what you infer is being used. Vibration can cause bits to come undone. The people who installed it should recommend an inspection period, and also have a plan for getting it down again! Link to comment Share on other sites More sharing options...
gil-galad Posted February 4, 2004 Share Posted February 4, 2004 There is some argument as to what is classed at temprary and what is permananent. I would also say it would be worth looking at the possibilities of fatigue on the truss if the run is long and the loading is not even. Link to comment Share on other sites More sharing options...
Ellis Posted February 4, 2004 Share Posted February 4, 2004 Don't quote me, but in some circumstances, the prescence of a permanent lighting rig might breach development control (Planning) regulations (use of premeses, etc). When I was at uni, the TV studio rig had to come down annually to prove it was temporary (it was in a listed building) Link to comment Share on other sites More sharing options...
