Suspended lights fitting ideas

[ipf]

Nice bit of Genesis 9:13 going on there.
Looking good and inventive way to future proof maintenance.
Why is it that insulation never goes down neat and ends up looking like scrambled eggs?

Like that when I found it. It might just have something to do with the original method of suspension. From the adjustable wire rope tensioner above the fitting, round the higher beam about 5m away and round the beam above the fitting position. In the 2nd picture you can see the 3/8''steel 'rope' over the two higher beams...and get that spacing from the bottom beam.
Heath Robinson, eat your heart out. It took some cutting and removing. It favoured a rat trap and took a bit of care.

Sorry for delay in getting these, been a bit mental. So you can see in the images, there's two wires, as I've said I believe these to be rated to 8kg each and the light is 7kg.

I spent a good half hour pinging footballs off it today and it's solid. But yes, the previous wire was straight drops, I've strapped this up with an angled wire which will put more strain on it I imagine.

I could wire it straight down as previous but it'll hang slightly lower I expect.

Angled support wires definitely increase the force in each wire. With two wires and a 120 deg angle between the wires, each wire will have a force equal to the weight of the object. As you increase the angle between the wires, the forces increase. With the angle you have there, I estimate that each wire will be subject to a force of about twice the weight of the light.

It's easy to calculate, or look up info on angled lifting slings.

You can get safety wires which would hold the fitting if one of the grapples broke.
Don’t need to be tensioned, just looped of the strut and through the eye bolt.

That's what I was thinking - continue to fix them as per photos but then have an untentioned safety wire going straight up in the event of them snapping. I'm going back up in the lift today, I'm going to try suspending them with straight drops to see how they react when hit.
