Unreeling and Installing New Wire Rope Without Damage

Learn the correct methods for unreeling, uncoiling, and spooling new steel wire rope to prevent fatal kinking and twist, with expert guidance from CML SARL in Douala.

A brand-new, premium-grade steel wire rope can be ruined before lifting its very first load. The physical transfer of wire rope from the manufacturer's shipping reel onto a crane drum, winch, or storage reel is the most vulnerable phase of a rope's working lifecycle. Incorrect unreeling or winding under uneven tension introduces permanent twists, kinks, and structural distortion that no amount of subsequent operation can correct. At CML SARL (Cameroon Maritime Logistics), Douala, we witness the costly consequences of improper rope handling across industrial and maritime sites in Cameroon. This engineering guide outlines the mandatory procedures for safely unreeling, inspecting, and spooling wire ropes onto equipment. ### The Anatomy of a Kink: How Damage Occurs Steel wire rope is manufactured under carefully calculated rotational torque balance. When unspooled correctly, the rope pays off straight. However, if a reel is laid flat on its side and the rope is pulled off over the flange, every single loop pulled off introduces a **360° twist** into the rope structure. As tension is applied: 1. The twist travels down the line until it concentrates into a loop. 2. If tension continues, the loop collapses upon itself, creating a **kink**. 3. A kink causes plastic deformation of the strands, severely displacing outer wires and damaging the core. 4. **A kinked wire rope is permanently ruined and must be discarded immediately.** It can never be straightened back to safe working co...
