An apparatus for providing reliable line traction spooling for hoists, winches, and other pulling and/or lifting devices is disclosed. In one embodiment, such an apparatus includes a motor and a drum rotated by the motor to draw in or let out a line from the drum. The drum includes a groove formed in an outer surface thereof to accommodate the line. A roller is provided to place pressure on the line against the drum. A roller consists of at least one indentation or protrusion on an outer surface to assist the drum in spooling the line onto and off of the drum. In certain embodiments, the roller is patterned in order to improve line traction. In other embodiments, a line is compressible in order to improve line traction.
