sam.henderson Posted October 22, 2004 Share Posted October 22, 2004 Hi Guys, I am going to be working on a show in a small studio type space (capacity aprox 250). We want to hoist a cage up with 2 people in it. We have some hugely experianced builder/ carpenter type people and an amazingly talented director but I dont know how it will work. What will we need to do this safely and to conform with H & S. Unfortunetly budget will not alow us to get the pros in (but if there is not a safe way of doing it we wont- so dont worry) Sam PS- The venue has no flying facilities at present.

Brian Posted October 22, 2004 Share Posted October 22, 2004 What height lift is required? Rather than hoist could you not raise? ie with something like a scissor lift? Link to comment Share on other sites More sharing options...
the kid Posted October 22, 2004 Share Posted October 22, 2004 Had a thought but do you meen like the cages you see in strip joints? If its like that you could try by asking there. Link to comment Share on other sites More sharing options...
tjkerr Posted October 22, 2004 Share Posted October 22, 2004 RSAMD has a show in right now where there using a "loadstar chain hoist" to lift and lower a cage with an actor in and out which sounds like what you want to do! This show is in the studio space...I will ask the TSM for the show what there plan is if they dont see this first they might post. Link to comment Share on other sites More sharing options...
sam.henderson Posted October 23, 2004 Author Share Posted October 23, 2004 Thanks for all the feedback so far, Yes like the ones in strip clubs. Only ebing raised about 4m (low celing height). Thinking about the chain hoist but how noisy is it? Sam PS- Its just like what you describe tjkerr! Link to comment Share on other sites More sharing options...
jagardner1984 Posted October 23, 2004 Share Posted October 23, 2004 Hi there, I am one of the TASMs on the aforementioned show. What we ahve basically done is put a beam clamp around the I Beam in the roof, then attached the Lodestar motor up, and hung a steel cage from it. The steel cage is rock solid - from 50mmx50mm steel, with a large clip on the top. The whole thing is welded and then decorated. It seems to be working a treat - tech next week. I think there are two things our TSM was especially cautious of: 1. The Point Load on the I Beam,2. The Integrity of the Cage. Both were looked into fully before we got anywhere near construction, let alone putting it in the air. If you need more info, PM me and I will put you in touch with her, James Link to comment Share on other sites More sharing options...
peter Posted October 23, 2004 Share Posted October 23, 2004 One other concern with LodeStars surely would be the noise of the motors? Link to comment Share on other sites More sharing options...
colinmonk Posted October 23, 2004 Share Posted October 23, 2004 is there a safety provision for motor failure? or point fail? only ask as am intersted... Link to comment Share on other sites More sharing options...
sam.henderson Posted October 23, 2004 Author Share Posted October 23, 2004 OK Thanks all! 2 things: Like I said (and peter) how noisy are these loadstars?? in a studio environment are they alright?? How quickly does it move??? Sam Link to comment Share on other sites More sharing options...
Pete McCrea Posted October 23, 2004 Share Posted October 23, 2004 Lodestars- If it's new then it'll be quieter than an old one. I think you'd know if it was to move during a show peice in a studio. Plus there's the clunk as they stop with the brake locking in (twice if it's a double breaked version). Lodestars move at between 8' and 64' per minute. You'll more than likely need a 3 phase supply, but there are single phase versions around I believe. Also lifting people comes under a whole different set of inspection regimes with respect to Loler. Check Chris Higgs books out for the details. Link to comment Share on other sites More sharing options...
oh lordy Posted October 23, 2004 Share Posted October 23, 2004 Hi Sam, to be quite honest you should get a pro to do it. If you are unfamiliar with the sound of a hoist you surely shouldnt be attempting to use one to lift personel in it. Sorry but get someone who knows and has done it before to do it for you.

sam.henderson Posted October 23, 2004 Author Share Posted October 23, 2004 Its like you read my mind Oh loardy, Having just had a look at some other topics on here and done some web research I was just about to come back and say that I am not confident to rig it or use it myself. I think we will probably get Stage Electrics in to rig it. However we still need to make the cage- so any ideas for that would be great. Thanks Sam Link to comment Share on other sites More sharing options...
slim_mcslim Posted October 23, 2004 Share Posted October 23, 2004 I was just about to come back and say that I am not confident to rig it or use it myself. I think we will probably get Stage Electrics in to rig it. I don't understand if you are not confident in the rigging of a single hoist then how you could be confident in the design and construction of a cage, which will have to be fairly strong to take being raised from a single load point.

sam.henderson Posted October 23, 2004 Author Share Posted October 23, 2004 Because I wont be making it or designing it properly just gathering ideas to pass on to the people who will be making it. I am just trying to get an idea for what we can do, I can assure you all that I would never attempt something like building the cage myself if I did not believe that I had the right qualifications and knowledge. not becuase it would controvine with HSE guidelines or for anything else other than the fact that I could not live with the fact that I had killed someone!!!

trussmonkey Posted October 23, 2004 Share Posted October 23, 2004 if you want to be really safe your probably looking for a double braked hoist. that way you could get around the whole secondary safety problem. Link to comment Share on other sites More sharing options...
