There are several articles in Yale Tech Briefs, USITT Tech Expo catalogs and USITT Technical Source Guide about using pneumatic cylinders as platform lifts or brakes.
A Technical Source Guide (early 90's?) and Exhibit #2 from the 1995 Tech Expo(some words are jumbled from scan conversion) are attached.
As Nick mentioned, Technical Design Solutions for Theatre (Yale Tech Briefs) Vol. 2 p.200 has an example as does Vol. 3 p246 and p249.
