What is the most versatile tool used in pulling underground cables?

The most versatile tool used in pulling underground cables is the capstan. A capstan is designed specifically for managing cable with great flexibility and control, making it ideal for tasks that require continuous pulling without the need to disengage the line. It's equipped to handle various cable sizes and types, accommodating different conditions found in underground cable installations. The design of a capstan allows it to provide consistent tension while minimizing the risk of damage to the cable, which is crucial when dealing with underground infrastructure.

Other tools such as a winch or hoist may excel in specific applications and have their own strengths, but the capstan's ability to provide smooth, adjustable tension makes it the go-to option for many contractors and technicians engaged in pulling cables in challenging environments. A pulley, while useful in redirecting force, does not have the same capability to manage continuous cable or offer the same level of control necessary for pulling tasks.
