YouTube - Air Spring Dump Trailer
Surprised she wasn't wearing the tongue of that trailer, when the box raised.
Wonder what the availability of these air springs are in that configuration. Anyone have more info on them?

I've used these in industrial applications for years, like lift tables, clamps, without fail. Check this link.Firestone Industrial Products Co. ~ North America Industrial Applications
Look at the last one it has 53,600 lbs of force applied right you could move anything, well almost.

And the advantage and cost comparison to doing the same comparable job/lift with hydraulic is what?
What did the woman "trigger" to get the trailer to raise in the YouTube vid?
I noticed she didn't demonstrate but a "lift" of an empty trailer. Was air added to the air spring to get it to lift?

It sure was easy with an empty trailer.
It appears to be about 10" in diameter and @ 100psi of air that would give roughly 11,000lbs of force. But hydraulics are positive displacement. The fluid wont compress, which means hydraulics will raise just as fast under load as empty.
Look at the volume of air required to fill that bladder with 100psi. How long would it take your air compressor to fill a tank that size to 100psi??? I am guessing longer than if it were a hydraulic trailer. That trailer with 7k on it looks like it would raise pretty slow to me.

Interesting.
To me the advantage of the air spring is the reserve capacity created by a tank. There's no cheap and portable way to store hydraulic energy. With a moderately sized tank, a very small compressor can store enough compressed air for a dump.
The inverse would also be true. The same sized motor could dump a lot faster or a lot more weight via stored compressed air than could be done with hydraulics.
I wonder how much these would cost.

- 1993 NH 2120 (the best), 1974 MF 135 (sold, but solid), 1947 Farmall A (bought, sold, bought back, sold again), 1956 MH50 lbt (sold, in 1980, darn it)
Maybe the advantage to air is the smaller compressed size, so the geometry can be easier and still have a low bed.
