ceo Bell Engineering did the Sandia Peak Aerial Tramway in Albuquerque - most recent major work done was a full cab replacement in 2016. They’re also working on rebuilding a gondola in Texas - or I’m almost certain I read somewhere a few weeks ago that they are.
Edit: Nope, you’re definitely right - I had thought they were still around - and they are, but they’re not in the ski lift business anymore. They did have a presence in the Americas though - Sandia Peak, El Paso, Banff, Vail to name a few places. The cab replacement completed in 2016 was done by CWA which is just another Dopp subsidiary– I did myself in by skimming rather than reading carefully.
Here’s an old ad that has a little bit of info on them.
