What is the component called that a rope is wrapped around when using a power cable puller?

The component that a rope is wrapped around when using a power cable puller is known as a capstan. A capstan is a rotating cylindrical device used to wind up ropes or cables, providing mechanical advantage to pull heavy loads. It typically features a smooth surface that allows the rope to grip effectively, enabling it to reel in or release the cable under tension as needed during installations or pulls.

The design of a capstan allows for multiple layers of rope to be wrapped around it, which increases friction and pulling power, making it effective for navigating challenging job sites or pulling cable over long distances. This mechanical tool is commonly used in electrical installations, especially when working with power cables that require significant force to maneuver.

In contrast, a drum typically refers to a cylindrical object used for storing cable or wire, while a reel can also be used to hold wires but is more associated with the storage of lighter materials. A windlass is often used for lifting heavy weights and can resemble a capstan but serves a different primary function in hoisting rather than the pulling mechanism used in cable pulling.
