When a non-rotating rope is used in a wedge socket, care must be taken to prevent which issue?

• A. Core slippage
• B. Wire pinching
• C. Surface abrasion
• D. Bending fatigue

Answer: (A)

When a non-rotating rope is used in a wedge socket, the key issue to prevent is core slippage. The wedge socket relies on the rope being gripped and the load being transferred through the rope's internal structure. If the rope’s core slides relative to the outer fibers under load, the load path becomes unreliable, reducing strength and risking failure at the socket. To avoid this, ensure proper seating, compatibility between rope construction and the wedge, and correct assembly so the core remains engaged with the outer strands. While surface abrasion, bending fatigue, or pinching can be concerns in other scenarios, they do not address the primary failure mode here.
