What is the purpose of a cable pulling tension chart?
2025-08-16A cable pulling tension chart is a critical planning tool used to determine the maximum permissible pulling force a specific cable can withstand without being damaged. It is not just about the winch's capacity; it's about the cable's integrity. These charts help engineers and contractors prevent catastrophic failures such as stretching, necking, or breaking the cable's conductors or compromising its insulation. By using a tension chart, you can:
-
Select the Correct Equipment: Ensure your Cable Pulling Winch has the appropriate capacity for the job.
-
Plan the Route: Identify potential problem areas with excessive friction, such as tight bends or long distances, before the pull begins.
-
Ensure Safety: Prevent dangerous situations on the job site by avoiding over-tensioning.
