How to select the right pulling rope?
2025-08-16Choosing the correct pulling rope is crucial for safety and project efficiency. Here are the key factors to consider:
-
Tensile Strength: The rope's minimum breaking strength (MBS) must be significantly higher than the maximum anticipated pulling force. A safety factor of at least 4:1 is recommended, meaning the rope's MBS should be four times the maximum working load of the pulling machine.
-
Anti-Twisting Properties: For overhead tension stringing, an anti-twisting braided rope is non-negotiable. This prevents the transfer of torque from the pulling machine to the conductor, which can cause severe kinking and damage.
-
Application Environment: Consider the environment. For overhead work, a heavy-duty steel rope is best. For underground projects, a lightweight, flexible synthetic rope is often preferred as it's easier to handle and less prone to corrosion in wet environments.
