What type of rope must support at least ten times the designated load?

The requirement that the rope must support at least ten times the designated load is closely associated with rotation-resistant rope. This type of rope is specifically designed to offer high load capacity while minimizing the risk of rotation under load, which can lead to instability and dangerous conditions during lifting operations.

The tenfold safety factor is a critical requirement in rigging to ensure that there is sufficient strength to handle unexpected stresses or overloads without failure. Rotation-resistant rope is engineered to maintain its performance under varying conditions and is often used in scenarios where safety is a primary concern, especially when lifting loads that could impose significant strain.

In contrast, while the other types of ropes may have their uses in different applications, they do not inherently adhere to the same stringent safety ratio requirements or may not be designed to handle the dynamic loads and rotations associated with lifting in a manner compliant with this specific safety standard. This makes rotation-resistant rope the appropriate choice for this particular scenario.
