5 Truss clamps needed asap (for next week) 15KG strength per clamps preferred.

Just a thought Al, are those still compliant if you use them with the block fixed the way you have it?
Shouldn't the block slip over the g clamp?

I think I last paid about 60% of the AC listed price for a recent order why not just keep spare clamps? they're useful

@Pj and the the others who uses these clamps.
I don't know who told you these clamps will he highligh adviced for kvants but think about the following situation.
You hang you kvant 13kg on a truss with safety's, the truss goes up and then the disaster strikes.
Truss comes down and luckily stops halfway instantly!!!
Your clamp which is tested MAX LOAD 15KG (your not allowed to use it with more weight) will fail!!!
A static weight isn't the same as something which is coming down.
I doubt the 250kg which the clamps i use will hold but it will hold allot longer then the 15kg clamps for sure.
It's up to you, but don't be disappointed when the insurance will say, sorry mister Pj we are not gone pay because the clamps you used where not mend for this situation.
And that for a difference of 20 euro's a clamp, i think take your responsibility and go for as safe as you can.

You are not correctly understanding the Safe Working Load rating, and therefore scaremongering, and also potentially costing yourself unneccessary money by buying massively over rated fixings (which is no bad thing, but do it out of choice rather than than misunderstanding )

They are usually rated to withstand N times the static load, where N is a number usually between 4 and 10, typically 4 to 6 for non-safety critical applications, and 10 for any application where it could cause risk to life (which would apply to most of our show situations overhead of a stage)

Note that (in the UK at least) use of a secondary fixing is only necessary if there is access to the area underneath the fixture. If there is no access, or the hazard is controlled in another way then it is not mandatory (although probably good practise from a fixture security point of view)

My projector is 12KG and not 15KG.
I have weighted this unit.
My projectors do not come close to the 15KG limit.
My other projectors weigh 9KG.

It's 15KG with a safety margin already taken into account.
Are you seriously convinced these clamps will rightout fail when you go over the 15KG?
The reason why they file them for 15KG max is that they feel that this is their super super save zone where there is NO way possible that it can fail.
Also no truss is going to fall down, the venue has this truss installed and it cannot be moved the whole ceiling is one big truss.

These clamps are used in shows and aren't exactly cheap, these are professional clamps sir astatic.
No offense really but the way I feel about it is that if you your self have never hanged up a projector before in a truss you should not make these statements without consulting someone yourself.

Also it's ment and not mend (just helping you out here preventing you to constantly make that same mistake).

The reason why I prefer you'd not do that is that there are people selling these clamps and because your giving the wrong idea about these clamps people could get mis-informed.

You are not correctly understanding the Safe Working Load rating, and therefore scaremongering, and also potentially costing yourself unneccessary money by buying massively over rated fixings (which is no bad thing, but do it out of choice rather than than misunderstanding )

Thanks Norty, way more informative and I prefer statements with actual facts to support the named statement.

Yeah you should put them over the clamp bar. I just arranged them quickly for the photo.

The UK forum 'Blue Room' has a dedicated section for rigging type questions, and as it's a predominantly professional forum, you get good answers, and often links to regulations and guidance, which is increasingly Europe wide, so of interest to a lot of people here.

Here's one about SWL if you have a stomach for it...

actually it is "meant" (just helping you out here preventing you to constantly make that same mistake)

Pieter Jan, why so unkind and trying to piss me off?
I was only helping you out.
If you don't want that just let me know, we are grown adults.
And i do expect a little respect from you when you talk to me, thank you!

Kind regards.

@Norty,

I understand what your saying.
I don't know how the insurance company's in the UK are but in here they try to find a way to get away with it if they can.
What i want to say is that when you work to the max of your equipment you take a risk.
I know, the maximum load is set to 15kg static weight, but with the kvant spectrum 1.6/2W of kvant it only leaves a 2kg space (one of my 1.6W is 13kg).
That's why i said better overate it to be safe and proof them you did all you can to avoid any problems then get involved into a discussion with the insurance company which you really don't want, not talking about if there where victims involved.

And i'm sorry to disagree with PJ but there have been some company's who told there rigging is the best and it won't come down.
Some of the employees of these company's can't say this anymore, so be prepared for the worse (i don't want to have a falling projector on my head even it was only 1 meter).
But maybe i'm a bit overreacting, who nows i'm a father of two little kids and got a little cautious when they got into the family.
