How to select the right pulling grip?
2025-08-16Selecting the correct pulling grip is crucial for a safe and successful installation. There are three key factors to consider:
-
Conductor Type and Diameter: The grip's bore or diameter range must perfectly match the conductor's outside diameter. A grip that is too large will slip, while one that is too small can damage the conductor's insulation or strands.
-
Required Holding Strength: The grip's maximum rated load must be greater than the maximum pulling tension anticipated. It is a best practice to select a grip with a rated capacity that is at least 5 times the estimated working load (a 5:1 safety factor).
-
Application Environment: For underground pulls through conduits with many bends, a rotating-eye grip with a Swivel is essential to prevent twisting. For overhead projects, a heavy-duty, double-weave grip is required to handle the high tension loads.
