An apparatus for providing reliable line 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 helical groove formed in an outer surface thereof to accommodate the line. A roller is provided to place pressure on the line against a groove in the drum. In certain embodiments, the drum comprises a groove which widens as it gets closer to the drum. In other embodiments, the groove is formed by sidewalls which are various shapes and dimensions allowing the line to be held in the groove.
