Which lifting device uses a drum to wind a cable or rope?

The correct choice is the winch because it specifically utilizes a drum around which a cable or rope is wound to facilitate lifting or pulling operations. The primary function of a winch is to exert force through the winding mechanism, allowing it to pull heavy loads vertically or horizontally. Winches are commonly used in various applications, such as towing vehicles, lifting loads in construction, and in marine settings for anchoring boats.

Cranes, while also used for lifting, typically employ a different mechanism that includes a boom and a hook, and they may use various methods to lift loads rather than a simple winding drum. Forklifts are designed for lifting and transporting materials over short distances and do not incorporate a drum mechanism. Hoists, similar to winches, can lift loads using a mechanism that may involve a drum or pulley system; however, they are more focused on raising and lowering loads vertically rather than the broader application of pulling.

Thus, the unique function of the winch, which revolves around the use of a drum to wind a cable or rope for lifting or pulling, makes it the correct choice.
