    摘要: An apparatus includes a drum to draw in or let out a line and a motor and transmission coupled to the drum to apply a torque thereto. The transmission includes at least one stage of gearing to reduce a gear ratio of the motor relative to the drum. A shaft couples the motor to the transmission and a locking mechanism selectively locks the shaft to prevent rotation of the drum. In certain embodiments, a braking mechanism may be provided in addition to the locking mechanism to slow the motor when the motor is not applying torque to the drum. This may slow the motor sufficiently to enable engagement of the locking mechanism.

    摘要: 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, a depth of the groove is equal to or greater than a radius of the line. In the same or other embodiments, a passive guide that physically engages and tracks the groove may be used to guide the line into the groove.
