Wire Rope Slings: One-Leg to Four-Leg Configurations

Master the design, angle factors, and load calculations for one-leg, two-leg, three-leg, and four-leg wire rope slings, fabricated to order by CML SARL in Douala.

Wire rope slings represent the primary connection between a crane hook and an industrial payload. Whether lifting a 40-foot container at Douala Port, positioning a generator at an oilfield site, or rigging precast concrete beams in Yaoundé, the geometry and configuration of the sling assembly govern the safety of the lift. Using an improper sling configuration or miscalculating sling angle factors can quickly overload individual sling legs, leading to catastrophic failure. At CML SARL (Cameroon Maritime Logistics), our Douala rigging facility manufactures certified one-leg, two-leg, three-leg, and four-leg wire rope slings compliant with European standard **EN 13414-1** and international lifting codes. This engineering guide details sling configurations, angle factors, and Working Load Limit (WLL) calculations. ### Single-Leg and Multi-Leg Sling Configurations | Sling Configuration | Description | Key Fittings Included | Typical Industrial Use | |---|---|---|---| | **Single-Leg Sling (1-Leg)** | Straight vertical lift or choker hitch | Thimble eyes, master link, safety latch hook | Vertical machine hoisting, pipe chokers | | **Two-Leg Sling (2-Leg)** | Bridle assembly with two legs sharing load | Forged master link top, thimble eyes, hooks/shackles | Machinery skids, shipping crates, standard loads | | **Three-Leg Sling (3-Leg)** | Three legs suspended from a master link assembly | Master link with sub-links, thimble eyes, hooks | Circular payloads, triangular skids, vesse...
