Caterpillar, that construction company that makes bulldozers and other heavy machinery, has its own smartphone, called the B15. Never heard of it? Yeah, you're probably not going to find it at your local AT&T store. It's primarily for construction workers, who have to worry about their smartphones falling a few floors from scaffolding, or having it ran over by a truck carry cement from a site.

In order to show off how durable their B15 is, Caterpillar pieced together this video to show the device can withstand a fall from 35 feet, and being crushed by a Cat 277D that weighs 4.6 tons.
