Abstract

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. In certain embodiments, the motor and drum are quickly and easily detachable from a structure by way of a flange and mounting bracket. The flange and mounting bracket have holes which are coaxially aligned. A pin or other fastener is used to join the flange and mounting bracket together.
