They get stacked on the bottom if he wasn't clear.

Thanks, I misunderstood. I thought he said the guy stacked them "on the forks".

There are some local guys that use lifts that I believe are Genie. They don't appear to have outriggers. They pile a bunch of road cases on the base and then fly 2 boxes of a JBL curve array beneath 2 subwoofers. The last time I saw them they were suspending the speakers from a nylon strap. The wind would make them turn sideways.
You can see the base of the lift very well in this video. I take it that these are the "not for entertainment use" model.

screen shot attached.

No Genie's are supposed to be used outside (in the wind) without guy wires.  If they are turning in the wind the rigging is screwed up too.

What you describe is nylon straps is more than likely spansets and that's how it is supposed to be done.  We use one set on the clevis and another around the back to keep them from sliding forward.  Using a flybar and rigging so they don't twist is the basics.

That's a single road case, if it's empty it's worthless, if it's full of sandbags that's another matter. 

I could not see the fork rigging or how this was leveled so not sure what is up.  I appreciate the video.

Unless those road cases are loaded with ballast, what's the point ?

Ya, Whatever. Just throw a '57 on it, and get off my stage.

Even with ballast, the SLA base configuration just isn't safe enough vs the Supertower's greater and more evenly spaced spread with levelers.

Best regards,

Genie offers no information on how to properly install guy wires, and I have not seen any way to install them without adding to the load of the tower or lift.  We have banned Genie towers from campus because nobody can provide an engineer's stamped drawing on how to deploy them safely.  To be fair, no stages, roofs, scaffold towers, or other towers go up without proper engineering documentation.  Genie makes great material lifts, but as a support for sound and lighting, I am not a fan, I've seen too many failures.

I am guessing the road cases are empty.
Attached is a photo of the same lifts where you can see the speakers they are flying.
