James Chillman Posted December 9, 2003 Share Posted December 9, 2003 I have been aksed by the teacher at my school in charge of Health and saftey to see if there are any alternitives to having to go up a ladder to get to the bars to rig the lighting? Any suggesstions (even if its remotley crazy) James Link to comment Share on other sites More sharing options...
Ike Posted December 9, 2003 Share Posted December 9, 2003 You could use motorised bars (or hand winched) to enable them to be lowered into the deck to rig, however, you would still need to get at the bars to focus. For focusing would a scaffold tower be a better option? Of course this depends on having a competent person to rig and de rig the thing as well as good access to the area under the bars. You would also require training in order to use it. Link to comment Share on other sites More sharing options...
James Chillman Posted December 9, 2003 Author Share Posted December 9, 2003 Scaffolding presents a problem! Over a certain height we must employ a company to errect the scaffolding tower. Is there a course that can be done to make me competent? James Link to comment Share on other sites More sharing options...
Andrew C Posted December 9, 2003 Share Posted December 9, 2003 What about ETCs new (not yet available) moving heads. Expected to be £3k+ plus motorised shutters. Details in the new year, deliveries around Easter. My choice at the moment is;- a) ladder & harnessb) cablenet from Slingcoc) 20 very sexy looking lanterns :D Link to comment Share on other sites More sharing options...
James Chillman Posted December 9, 2003 Author Share Posted December 9, 2003 if I used a harness where would I attach it to that is secure? James Link to comment Share on other sites More sharing options...

I dont know your age so im just guessing that you are 16 or under. While you can go on courses to become competent, in the sense you know what you are doing and can do it safely, many insurence companys will simply not allow you to erect or dismantle scaff towers. I can't however see any reason why, with the proper training and supervision, you could not use the tower to rig from. EDIT: as for harneses it could involve having rigging points instaled and wires slung between them to clip into. cablenet from Slingcothis may well be the best option depending on your venue. I realy have no idea what I am talking about when it comes to these so I will leave somebody else to explain. Link to comment Share on other sites More sharing options...
Andrew C Posted December 9, 2003 Share Posted December 9, 2003 Depends. It needs to be a girder or similar capable of taking the dynamic load in N of a "standard" focuser (100kg?) falling of the ladder and dropping X metres, accelerating at 9.8mss. The girder should not have sharp edges to cut into your strops. You should consider shock absorbing lanyards, but these should not be so long as to allow you to hit the floor before it arrests your fall. In a nutshell, you need professional advice, and a site visit to ascertain what equipment is needed and how it should be used. Link to comment Share on other sites More sharing options...
mac500 Posted December 9, 2003 Share Posted December 9, 2003 Catwalks, wire-tensioned grids all viable options except they're probably all very expensive to install especially in a school environment. Or using a rig of VL1000's. Link to comment Share on other sites More sharing options...
richard Posted December 9, 2003 Share Posted December 9, 2003 I would heavily advise against the use of any permanent intelligent lighting in the rig, just because the lights are able to move themselves does not mean that they willl change their own lamps when they blow, or fix themselves. The art to using a moving light is not just moving it, you need to position it for the specific production and maintain it so that it works. After seeing how most schools maintain their kit (yearly if that) I can't see that moving lights would be very happy, and moving a moving light with a ladder is not an easy thing to do (especially lamps such as the VL1000 of ETC's thing - which are massive and heavy). I would also doubt that harnesses would be a viable option - all such systems rely heavily on adequate training and supervision being in place, and many insurance companies and Health and Safety advisors would, I expect, doubt the ability of a child (or person under 16) to be deemed competant in such practices. I would think that the only way that you could produce a working model where students were allowed to work at height would be some kind of tensioned grid that you can walk on (as mentioned) although certain procedures would still need to be followed and certain supervision required to ensure that items were not going to fall from the rigging area on to people below.

Andrew C Posted December 12, 2003 Share Posted December 12, 2003 Your bar still has to take a huge dynamic load, which they almost certainly weren't designed for. Link to comment Share on other sites More sharing options...
robdavy Posted December 15, 2003 Share Posted December 15, 2003 I'm suprised no one has suggested a Geni Powered Lift. As far as I'm aware, they're quite favoured by LEA's/Schools versus Ladders.They're not cheap (couple of £k), but they can be used for alsorts in a school. Anyone got any thoughts?
