Fisher Men at Caspian Sea
They are tightening the creel.
The back tractor contains a huge winch, which pulls the orange rope, and the tractor is attached to a heavy concrete stone box with another thick rope (in front of it).
The other tractor (front one) is used for carrying the green trailer, which contains the rest of the rope gathered from sea!
Tree men are fixing problems of pulled rope to reuse it tomorrow...
