So, while I was searching youtube for a video to convince my sisters that you could crush a can using nothing but changing air pressure, I found this. It’s the coke can experiment that everyone loves… but on a bigger scale
First of all, the video posted by huberje is not of a backhoe, it is of an excavator. Second, both are designed to handle the situations shown, the backhoe just has modified outriggers to help it attach to rail cars.
Here is a promotional video showing some of what excavators are designed to handle.
Look up the Menzi Muck if you want to see a excavator built for extreme terrain.
