Abstract
A winch is described that includes a drum, a motor and transmission, and a tensioner. The motor and transmission apply torque to the drum, thereby enabling the drum to draw in and let out a line. The tensioner is positioned adjacent to the drum, such that when the line passes between the tensioner and drum, the line is in frictional contact with the tensioner and drum. The tensioner rotates with a linear speed exceeding a linear speed of the drum as the line is let out from the drum, and rotates freely as the line is drawn onto the drum. Methods for making and using the winch are also described.
