The winch consists of a drum (11) surmounted by a pivoting component (2) with a stop (9) to take a turn of the rope (1) and a curved guide groove (8) in its edge for the rope's free end (6). The pivoting component acts as a lever, reducing the effort required to haul in the rope, which is pulled manually at an angle of 90 degrees to its incoming length. The winch drum has a toothed inner ring and pawl (12) allowing it to rotate in one direction only, and the pivoting component can be set in different positions to vary the gearing.
