Video captures moment standard excavator encountered that nasty ol’ gravity.
There are several immutable laws that govern the way in which the known universe operates: Every action has an equal and opposite reaction; what goes up must come down; if something’s going to go wrong, it will do so shortly after the guy with the video camera pitches up.
And now, we would like to add one more slightly more complex and rarely encountered law to that already exclusive list. “If you build an excavator ramp against a wall, it is generally best not to then knock down that wall while your excavator is still sat on the ramp”.
