The types of Cable Pulling Winches are primarily defined by their pulling mechanism and power source.

• Bullwheel Winches: These are the standard for professional OHTL and underground projects. They use a powered, multi-grooved bullwheel to generate a constant and controlled pulling force, while the rope is stored on a separate, non-driven reel. This design provides superior tension control and is ideal for long, heavy pulls.

• Capstan Winches: These are often smaller, more portable winches. The pulling rope is manually wrapped around a spinning vertical or horizontal drum (the capstan). The operator maintains tension on the free end of the rope to generate the pull. They are excellent for urban projects, short pulls, and in confined spaces like manholes.

• Drum Winches: The pulling rope is spooled directly onto a powered drum. This simple design is effective for many applications but can have inconsistent pulling force and speed as the rope layers build up on the drum.
