What is a good rule for how far away from the dead end/break-over structure to locate pulling equipment?

The choice for locating pulling equipment at a distance of 1/3 the span length from the dead end or break-over structure is grounded in principles of safety and efficiency in line work. This distance helps to ensure that the pulling forces are evenly distributed and reduces the risk of undue stress on the line and the structure itself.

When pulling lines or cable, the geometry of the operation contributes significantly to the handling of tension and potential hazards. Locating the pulling equipment at this distance allows operators to manage the load effectively, minimizing the likelihood of damaging the infrastructure. It provides adequate working space and aligns with safety protocols to avoid accidents that might arise from being too close to the structure or having equipment operating outside optimal distances.

This practice is informed by lineman experience and industry standards, which emphasize that a proper setup reduces strain and improves the overall execution of tasks during line installation or maintenance.
