Hydraulics at "O"

[derekleffew]

Other than the orchestra pit and maybe a scissor lift, how many have hydraulics in your theatres? I thought this might be interesting to some: Entertainment Engineering - Volume 5 Issue 12.

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.

Ok, you gotta explain how they did that. Ram connected to cables I assume?

The only hydraulics we have are the man lift and the elevator.

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.
