What tool do linemen typically use to help tension wire during installation?

Linemen typically use grips to help tension wire during installation. Grips, specifically wire grips or cable grips, are designed to attach securely to the wire while allowing for effective pulling and tensioning techniques. They provide a strong hold on the wire, which is essential when linemen are working to install or adjust the tension of overhead conductors.

Using a grip ensures that the tension is applied evenly and safely, preventing damage to the wire and maintaining proper alignment during the installation process. This tool is essential for ensuring that wires are properly tensioned to withstand environmental factors such as wind, ice loading, and thermal expansion without compromising cable integrity.

While pulleys can assist with redirecting forces and creating mechanical advantages, and hoists are used for lifting heavy objects, they don’t specifically serve the purpose of griping the wire directly for tension adjustments. Shackles, on the other hand, are primarily used for connecting lifting or rigging equipment but do not function to apply tension to the wire itself. Thus, grips are the most appropriate tool for this specific application in lineman work.
