What safety factors should I consider when using a cable pulling sock?

2025-08-14

Safety is paramount when working with cable pulling equipment. The most important factor is the Minimum Breaking Strength (MBS), which is the maximum load a new, unused sock can withstand before failure. To ensure safe operation, a Safety Factor (SF) must be applied to the MBS. We recommend the following:

  • For ground-level horizontal pulls: A minimum safety factor of 3:1.

  • For overhead pulls or lifting: A minimum safety factor of 5:1.

  • For high-risk applications: A minimum safety factor of 10:1.

Before each use, it is crucial to inspect the cable sock for any frayed wires or damage. Always select a sock that is correctly sized for the cable diameter to ensure a secure and effective grip.
