He's talking about the Bensink gate.http://www.bensinkbmxgates.com/8pgate_en.html
The gate actually drops into its own dedicated concrete pit. i think I heard somewhere that an 8-Man installation at a Euro-based track was like US $37,000 (I'd imagine shipping that whole assembly to the states would add another $5k easily, plus crane rentals and the expenses of prepping the area). It is all self contained, so you do not have any above-ground air or electrical to tangle with, which is kinda cool. There is a video of an installation at the above link.
For far less (around $25K) you could get your track a Pro-Gate "Safety Gate" this is where each position is a separate gate, and is set up in such a way that you could put your foot under it on a drop and not be injured.http://www.progate.net/14.html
I think I heard that the Worlds is using this type of gate this year.
So sorry to hear about your injury. When I think of a fully loaded steel gate falling on someone's arm, it makes me cringe as if someone said "I got kicked in the nuts by a lead boot."
Heal fast and straight.
