Answer from Ningbo Changshi: The primary difference lies in how they handle the pulling rope and manage tension. A capstan winch uses a rotating drum where the operator manually wraps and controls the rope. It's excellent for applications where you need to accommodate long, unlimited lengths of rope and can be operated by hand with precise control.

A bullwheel winch, on the other hand, utilizes a grooved bullwheel (or several bullwheels) to capture and apply force to a continuous pulling rope. The pulling rope is stored on a separate storage drum. This design is ideal for high-tension, long-distance pulls because the bullwheel maintains a consistent pulling force without the operator having to manually wrap the rope. For heavy-duty cable pulling in overhead or underground projects, a bullwheel winch is the superior choice. It provides a more consistent, powerful, and safer pulling force over long distances, which is a key feature of our hydraulic puller-OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioners.
