Which component is essential for back stringing a pilot line without climbing the tower?

The component essential for back stringing a pilot line without climbing the tower is the finger line. A finger line is typically a lightweight line used to guide and pull a stronger line through the sheaves and towers without the lineman needing to ascend.

This line allows the lineman to manipulate and position the pilot line from a safe distance, minimizing the risks associated with climbing and ensuring that the installation or maintenance process can be completed more efficiently. Its usage is particularly beneficial in the context of safety and reducing the amount of physical labor required on-site, which is crucial in the electrification and utility industry. The finger line’s role is pivotal in connecting to the pilot line and facilitating its movement through the desired path.

In contrast, the other options like a basket, sheave, and pulley are components used in different capacities, such as lifting or guiding loads, but they don’t serve the specific purpose of allowing the back stringing of a pilot line without physical ascent.
