Abstract
A rescue hoist includes a cable drum that translates along and rotates around a cable drum axis. The rescue hoist includes various components that are supported on the hoist frame and that extend at least partially through the cable drum. A first bellows is mounted to the frame and attached to a first end of the cable drum, and a second bellows is mounted to the frame and attached to the second end of the cable drum. The first bellows and the second bellows expand and collapse as the cable drum translates, such that the first bellows and the second bellows isolate the rescue hoist components from an operating environment as cable drum translates and rotates.
