You don’t see many operation videos that are nearly as interesting as this one. And better yet, it only gets more interesting as it goes on. The video is a compilation of situations shot in Taiwan originally posted to YouTube by user wEnYi Liu.
First we see the operator working in a bit of muck, tilting the machine nearly to the tips of its treads several times. Then we see what he was working to pull up: a giant boulder. Then we see him working to climb an extreme grade. Check it out below.
