The industry is changing

摘要

Pit & Quarry magazine has been around for nearly 100 years, and looking through old issues, I'm struck not by how much things have changed, but by how much things have stayed the same. Go to the "Looking Back" page at the end of most of our issues (page 56 in this one), and you'll often see 50-year-old equipment that doesn't look all that different from what you use today.
