Which rope type is typically used for hauling and fixed lines rather than fall-arrest?

• A. Static rope
• B. Dynamic rope
• C. Kermantle rope
• D. Nylon rope

Answer: (A)

Static rope is designed to have very little stretch under load, which makes it predictable and stable for hauling loads and setting up fixed lines. In hauling and fixed-line work, you don’t want the rope to lengthen as you pull or to rebound, because that can shift anchors and complicate operations. Dynamic rope, on the other hand, is built to stretch to absorb fall energy, which would create dangerous forces in fixed-line or hauling scenarios. Kermantle describes a rope’s construction (core and sheath) and can apply to either static or dynamic types, so it doesn’t by itself define suitability for hauling. Nylon refers to the material, but the important factor for these uses is how much the rope stretches, not the material alone. So the best fit for hauling and fixed lines is static rope.
