Professional Answer: The choice between different types of automatic cable pulling machines depends on the specific project requirements. Capstan winches, for example, are highly versatile and excellent for longer pulls with unlimited rope length, as they rely on friction around a rotating capstan head. They are often used for general-purpose pulling. Our specialized hydraulic pulling winches, on the other hand, are designed for high-tension, heavy-duty applications, such as OHTL stringing, where precise control over pulling force is non-negotiable. We manufacture a full range of equipment to cover all needs, from lightweight, portable devices to robust, high-capacity machines for the most demanding power projects.
