A translating body rescue hoist includes a fixed frame and a carrier supported by the fixed frame. The carrier rides on bearings such that the carrier is capable of reciprocating relative to the fixed frame. The carrier supports a cable drum and a level wind mechanism. A drivetrain is mounted within the cable drum and driven by a motor mounted to the carrier. The drivetrain drives the cable drum, and the level wind mechanism is driven off the cable drum. As the cable drum rotates, a cable is fed off of the drum and through a fixed payout point. A follower is fixed to the frame and interlocked with the level wind mechanism such that rotating the level wind mechanism drives the carriage in a reciprocating manner. The level wind mechanism is self-reversing allowing the stationary frame to reciprocate while the level wind mechanism is rotated in a single direction.
