Crane collapses into water after dozer shoves it onto barge that doesn’t stay put

How this didn’t end in someone being very badly injured is a miracle. As you’ll see in the video below, this crew is loading a crane onto a barge by pushing it along with a dozer. Everything is fine until the barge starts moving—without the crane fully on board. The crane goes for a swim and its boom bends in half, falling atop the barge, somehow avoiding the crew just below.
