| Title: |
Winch Apparatus |
| Abstract: |
Provided is a winch apparatus including two exchangeable and
interchangeable gears connecting a motor to a drum, the drum being
operative to extend and retract a flexible line. By exchanging and
interchanging the gears to effect a change in the ratio of the diameters
of the first gear to the second gear, the torque and the linear speed of
the flexible line are adjustable, permitting the same winch apparatus to
move heavier loads at lower speeds, or lighter loads at higher speeds.
