The "digger" has a pivoting arm with a scoop at the end.

The line that that attaches to the end of the arm, goes over the white sheave  (barely visible on the right)

and then goes to the windlass- the blue wheel and axle. 

The arm extends so far out that we needed a brick as counter-weight

to keep the digger from tipping over.
