Typically, projector lifts and projectors ARE NOT UL approved. However, the parts (motor, power supply etc) are UL approved. I had an installation in San Francisco years ago where the electrical inspector demanded UL approval of the lift and the Projector. I had to hire Underwriters Laboratories to send an engineer to travel to San Francisco and write a report. The report did not give UL approval but indicated that since the parts were UL approved the installation was probably safe. This cost $2500 in 1992 dollars. The building inspector accepted this report in lieu of actual UL approval.
Since then I've seen hundreds of projectors and lifts installed, none UL approved (only Sony projectors are UL approved as far as I know) without comment by electrical inspectors. Luck of the draw!
