descending rigging/trussing.

[goboloco]

hi there. I have 2 spare trusses, and 8 or 12 stairville l.e.d. moving heads that I never used in my current "show"{ a big night club} . I kept em back,never used them, as I all ready had 4 trusses with 20 moving heads mounted 50ft up.

 

NOW......... im fed-up of my current lightning rig. I was going to add the remaining trusses, and suspend them below the others, as I have plenty of head room. I would like to have the additional trusses lower on command. to close in on the dance floor .the "u.f.o" landing effect/ tons of stroby truss lights. like a boxing title fight, or indeed a Rush concert.

has anyone any experience with installing heavy duty servo motors? I would love to hear some storys about movable rigging. in any enviroment.

 

regards, Goboloco.

Truss rising and lowering over the audience is not to be taken lightly. Get yourself to PLASA show and see the truss and motor suppliers. Have some figures ready for loads, heights and ratings of the loading points. Get a specialist rigging company in to do the install and provide all the documents needed to comply with your national regulations.

Have a look at Kinesys (http://www.kinesys.co.uk) - it is a chain motor based system designed for lowering and raising trusses during shows to preset limits. We use it with Vector primarily for our installed motors to get trusses in the air quickly, but have also used it to lower a DJ stage to the floor during an event.

Be aware that - "Moving a load over people" = "Not at all cheap"

Kinesys is great but you can't buy it with your pocket money. For 2 trusses you'll have to buy all the expensive bits and then just 4 of the cheap bits so it'll be quite uneconomical.

 

You can buy an older IBEX automation unit for much less.

 

However, unless you're automating, you can just control them manually using 4 chain hoists and a 4 way controller... but as has been said, if lifting them over people they need to be Cat-1 motors and use a suitable form of attachment to the truss (such as gacflex). If flying over the public I highly recommend you bring in a rigging company to do the job for you.

Indeed Andrew . I would not take the safety of the customer for granted . I'm sure there would be concideable expense . However - I already have the moving heads and trusses .the venue has over 1000 people on a sat night , and my boss understands the importance of dramatic effect from lights and projections -I'n conjunction with the music .

I have no problems with a budget of 20k for motors and ancillerys .

Plasashow.com is a month away, be there and see the suppliers for motors and control gear.

 

The days of just doing it are over, you really do need a papertrail to assure your insurers that you are operating safely. SO! load rating certificates for the rigging points, proper fastenings and control for the motors, and properly calculated load handling for the truss itself. Also you need to add a system to get power and DMX to the flown lanterns.

 

Your National regulations may stipulate a service interval for the moving truss, this service record is part of the paper trail required for continued safety and compliance.

Will there be beer at this show you talk about :)

Yes ad yes to a paper trail . Compliance to insurance regulation is must I'n Ireland . The entertainment industry is literally on it's knees due to regulation v cost .

I'm just glad I have a decent budget .

 

My Martin 575s and jp vary scan p3's .....are they concidered " old " yet ? I feel like I still have not gotten te best out if them yet with regards programming ....

Why do we need to defend LCD panels? No one is attacking them as far as I can see?

Sounds an ideal application for a self-climbing truss with a zero-fleet hoist inside it - like the one we introduced at ABTT this June. 350Kg on the truss, 3-4 lines, 12m travel, dual brakes, control & BGV certs. You could probably get three for your £20k budget.....! See it at PLASA on stand 2-R28.

didnt know the Blueroom has turned into a sales opportunity ;)

 

I doubt a self climbing truss in a nightclub is going to be very safe with all those p***ed up punters about.

 

if you have the budget definitely invest in a Kinesys system. If you only need a couple of trusses to move and the trusses are not very long then a couple of hoists on each with a load arrester as a back up could be a viable option. You will need to keep the speed low ish and avoid any fast accelerations otherwise the load arrester will lock up !!

 

you could probably do 4 hoists with all the Kinesys bits an pieces and control software and training for £20k ish.

 

give them a call. Speak to Dave Weatherhead or Martin Honeywill.

 

Employ a rigging company or to have a look over the plans for you. I can recommend a couple of good people for the job if you PM me.

Moderation: Chas replied with a direct recommendation of a solution to a posters problem. He did not show prices, or other frowned on information. Well within the T&Cs.
