More seriously, those things are pretty cool. There are several
manufacturers of them. They use them for news vans as well. Do you have
any information on the air pressure and volume required (some are fairly
low pressure, high volume.. others are high pressure, low volume).
Properly maintained, they'll cycle up and down several times a day for
years. They're also pretty fast (as in seconds to extend).
What they may not have is a huge amount of sideload capability, especially
while extending or retracting. The ones I've seen have been designed for a
top load of a few square feet (maybe 6-7). Maybe some fairly low windage
thing like a spider beam or a telerana would be appropriate.
