While both perform a pulling function, they are designed for different applications. A winch for underground cable laying typically focuses on controlled, powerful pulling over a shorter distance through ducts and trenches, often with high friction points. In contrast, an overhead line stringing winch is designed to handle longer spans and different tensioning requirements, and may also be used for conductor recovery. Both require precise tension control, but the specific features and accessories, such as drum size, rope type, and capacity, are tailored to their respective environments.
