Projectors in Sports Halls
Good Morning All!
We've recently had a projector fitted in the sports hall here... I'm sure you've already guessed where this is going...
When the hall's used in the evenings/weekends, the little toe-rags are obviously booting balls at it as hard as they can to try to move/damage it...
We got a secure enclosure for it, and there are guide wires securing it in place, but they're obviously not doing the trick...
I'm thinking a cage built around it but not touching it at all would be the obvious solution, but it's at quite a height, so seems a bit of a H&S nightmare...
If you've got a projector in your sports hall, or are aware of other more suitable/effective methods of ensuring it's not moved...

Exactly like you said, we would install a protective cage around the projector so that the little "darlings" couldn't damage it as easy (they'll have to be more creative). Regarding the H&S, you're right. Depending on the height, we'd probably use scaffolding or a mobile crane.
Let me know if you need any quotes

Do you have any photos of what you mentioned? I'd like to be able to show something to the powers-that-be and say this is what we need...

Hmmm, not sure chap. Let me have a word with engineering

Not a problem...
I'll get onto the company that installed it too...

Aren't they being supervised? Bill the department that is meant to be supervising for the damage and time to correct the problem. They'll soon learn?

It's done through an external lettings company, and there were a few users over the half term break... we will be charging them for some of the preventative measures we implement though...

A cage will stop damage but it won't stop it moving. I'm guessing it will be on a fairly long pole? The longer the pole the more the projector will move with on 1 degree of movement.

Seems odd that the company you used didn't offer you a security cage as an option, it would be logical to offer that for a sports hall. With regards to H+S, if a company has the correct credentials, training and equipment it should not be an issue.

It does have a security cage, to protect it from damage / theft... but that doesn't stop it moving on the pole...
I'm talking about a separate (probably wire) cage with a space between that and the projector...
I know what I mean, I'm just not describing it very well lol...

Ah I see, my bad. I guess the wire would have to be pretty solid though. The force that some lads can kick (or throw) sports equipment is ridiculous.

So do you have a projector that drops from the ceiling projecting onto a wall XX feet away?
Based on what you have what about using wire strops, I'm talking like sailing yacht mast type here so that it is help in position and cant be moved.
Surely a very short throw projector would of been better.

Ah, so i take it this link won't be of any use to you?

There are a number of options, you can use and Ultra Close Focus Hitachi (it fastens to the wall above screen or whiteboard) and with a cage on those they are quite tough, or a tile mount if you have a ceiling void it lowers the projector for use then hides it behind a tile when not in use in the ceiling protecting it from target practice.

I've done this, we fixed the projector on a 50cm unicol pole on an I beam clamp, and then using I beam clamps we had a cage created out of 1" steel mesh attached to the I beam with beam clamps with a hole cut for the lens and filled with plexi-glass the cage had an all round clearance of 30cm to ensure any shock was not transmitted to the projector. If I can find some pictures I'll post them.
