A beautifully done, video series on quarry equipment and operation. Photography is unique and voice-over is sexy. ... Most entertaining. Of course, CAT equipment is featured. Go here >>> https://www.cat.com/en_US/by-industry/quarry-aggregates/quarry-series.html
I looked at the first one. Nice series for general knowledge. It's shot in the dark to focus viewer attention on the lights and machines and hide imperfections is the surrounding area. I'm guessing it's a nice series of propaganda programs to possibly generate interest in young people coming into the business. I'll try to watch more as I get time. Thanks for sharing
