I have a small portable lift that is made for stage use. I also have some pneumatic rams that no one has ever touched, that is about it.

All of our linesets were hydraulic, before they were replaced a year and a half ago with an all-new electric system. We have something like 34 linesets.

What's a hydraulic?
At mai school we have manually operated flylines capable of lifting no more than 10 pounds.(Well probably more, but...)
Nearest hydraulic thing I can think of is the elevator that goes from lobby level to stage door level(half a floor)

We've got a pallet jack. Does that count?![]()
Sounds about right. I never used the system myself, though. I do know that the linesets were divided up into groups of three, and you could only move one of the three at any time (I think we had only 1/3 the pumps). It was also a royal pain to work with, because there was like an 8:1 ratio making it nigh impossible to fly anything in to any precision. It also took forever for something to move.
In comparison, the new electric system is an absolute dream - fully automated, you can move any six linesets at once, and quiet as a mouse.

For a basic description see this:
HowStuffWorks "How Hydraulic Machines Work"
If you've watched construction equipment - backhoes for example - you've seen hydraulically powered equipment.

Okay. Aside from the scissor lift and the man lift, we have a portable scissor lift for raising set pieces, two hydraulic paint bridges in our paint shop, a floor jack in the scene shop, and a class IV forklift.

Hm... the only thing that I can think of is the swell box on the Organ... Oh, wait... that's pneumatic. Does that count?

I know it's not hydraulic, but if anyone has worked with spiralift systems, I'd be interested in hearing their thoughts about them versus hydraulics.

Nothing other than our genie on which the hydraulics recently burst so I havnen't one and some lamps that need replacing for a show on Thursday. Yup, it sucks.
I have a question, how do you aim lights when you have an electric that comes down? Wouldn't you have to move it constantly? Maybe I'm missing something.

Commonly known as "bounce focus" or "yo-yo focus": Bring in the pipe, make adjustments, fly to trim, repeat until satisfied, or until you give up from frustration.

Hydraulics? Well, we've got a weelchair lift down to the pit. Other than that, we have access to a scissor lift and a smaller genie lift, both of which I'm pretty sure use hydraulics. When we can't get a hold of the lifts, which is pretty often, we do a yo-yo focus. The more often you have to do it, the better you get at it. Go figure.

Pshht, Genie lift.
