How do you load a dumptruck with a dozer?

This video is currently doing the rounds on the internet again even though it was first uploaded in 2011. It shows some ingenuity from the dozer operator to keep production going one way or another.

With the primary excavator and one dumptruck broken down on this job somewhere in Canada, the team try to keep material moving by reversing the truck right back into the bench while the Cat dozer operator attempts to load the truck by simply pushing material into the butt. Not an ideal or profitable way to load muck but at least they got one more load shifted on the day!
