Abstract
A winch assembly including a mount attachable to a vehicle, and a guide attached to the mount; including a winch having a drum for winding and unwinding a line, and a motor for driving the drum about a winding axis, wherein the drum has a helical groove for receiving the line as it is wound. A frame connects to the first and second end of the drum and is adapted to move relative to the guide so as to synchronize movement of the drum along the winding axis so that the line is aligned with the helical groove during winding and unwinding. A rod is attached to the frame and generally parallel to the winding axis, and passes through a hole in the guide, allowing the movement of the drum along the winding axis but preventing the frame from rotating about the winding axis is disclosed.
