Choosing the correct rope is a critical safety factor. We recommend following this two-step process:

1. Calculate Pulling Tension: First, you must accurately calculate the maximum pulling tension your project will require. This calculation should account for the cable's weight, the length of the pull, and the friction from rollers or conduits.

2. Apply the Safety Factor: Once you have the maximum pulling tension, you must choose a rope with a Minimum Breaking Strength (MBS) that is at least four to five times that value. This is a crucial safety factor that accounts for unexpected shock loads and rope wear. For example, if your calculated pulling tension is 5 tons, you need a rope with an MBS of at least 20 tons.

The rope's diameter will correspond directly to its strength rating; a larger diameter typically indicates a higher breaking strength. Always choose a rope with a certified MBS that far exceeds your project's needs.
