Ropes and Sheaves: Best Practices for Proper Line Leading

What is the best practice for keeping the ropes within the sheaves?

a) Lead the line from a center sheave when there are more than two sheaves
b) Lead the line from an outer sheave

Answer:

The best practice for keeping the ropes within the sheaves is to lead the line from a center sheave when there are more than two sheaves.

When there are more than two sheaves, it is advisable to lead the line from a center sheave to keep the ropes within the sheaves. This practice ensures that the tension in the line distributes more evenly, reducing strain on the sheaves and preventing the ropes from slipping off.

By leading the line from a center sheave, the force exerted by the tension is spread out and directed towards the center, keeping the ropes securely in place. This method is more efficient in maintaining the integrity of the system and minimizing potential risks.
