I'm looking to purchase a technocrane-style telescoping crane in the range of 20ft to 25ft. Here's the catch. I need this telescoping crane to be able to do moves over timelapse periods of time -- IE, to make a pre-programmed move over a period of, say, 10 hours. Or 8 hours. Or three minutes. I also need it to be able to do real-time moves with an Epic filming 24 frames per second, like any normal telescoping crane would.
Any suggestions? The more portable the crane, the better. Does anyone have ideas for which crane might be best? Does anything like this exist already, or would it require special software, special motors, etc?
(I am NOT looking for information about a single, custom-made crane that already exists in the hands of one person. I am looking to buy a crane from a major crane manufacturer, and then make any modifications necessary).
