Moving head on a tripod

[Crash_Override]

What are your thoughts on mounting a moving head to a tripod?
I would mount it on the center of the tripod, on top of the T-bar with 2 static lights(ETC CS spot/par) on the ends of T-bar?
Moving head weight: 9.9 kg (21.7 lbs) Robe LedBeam350. Stand: https://www.thomann.de/intl/hercules_stands_hcls700b.htm Hight about 3m (9ft).
I think two moving head hanging from T-Bar would be even worse?

I'd sandbag the hell out of them. You have two heads moving in sync and that could be a little bit of momentum swinging around at the top of the tree

Oh, forgot to add that it will be used for theatre, so not a lot of movement and usually with decent fade times.

What’s your opposition to a 10’ stick of truss and a 2 x 3 base plate with a pipe at the top? It would be the same footprint at the bottom.

Regardless if the tripod is rated to hold the weight go for it but any kind of movement could spill it as you have the tripod loaded heavy on one side with the mover. Even with a sandbag stack it only takes one kid to say hey watch this and swing it like it’s rock n roll.

I wouldn't do it, to be honest, even though you'll see disco Dave doing it every weekend at wedding receptions. Too easy for the stand to tip, even when well ballasted.

Depends a lot on where it is, as others have noted.

You'll need a *really sturdy* tripod, like an old ITE, designed for 100lbs of camera and prompter, to avoid torquing the tripod as you move the light, although that's less important on a light than on a camera. As long as the moving fixture is centered, and attached with a 5/8-18 (or maybe that's -16?), you can probably get away with this.

But like Amiers says: why not just truss?

@Jay Ashworth, my brain went the same direction, but if you look at the link it's actually a proper light stand being discussed rather than a camera tripod.
