As **Cameroon's leading wire rope steel supplier**, CML SARL (Cameroon Maritime Logistics) supports ports, shipping companies, contractors, mines and factories with dependable steel wire rope and the expertise to use it safely. Choosing the correct diameter and breaking load is essential for safety. This guide by CML SARL presents typical sizes, approximate breaking loads and the method to select the right rope. ### How to select the diameter 1. Determine the maximum load on the rope (including hook block and rigging) and the number of falls. 2. Apply the design factor required by the application (for example around 5:1 for general lifting slings, often higher for cranes according to the standard and the crane maker). 3. Required minimum breaking load = load per fall x design factor. 4. Choose a construction and grade whose minimum breaking load meets this value. 5. Check the drum and sheave diameters (D/d ratio) are compatible with the rope. ### Indicative Minimum Breaking Loads (35x7) | Diameter | - | Min. breaking load, grade 1960 | Approx. mass | | --- | --- | --- | --- | | 8 mm | - | 45.2 kN | 0.29 kg/m | | 10 mm | - | 70.6 kN | 0.46 kg/m | | 12 mm | - | 101.6 kN | 0.66 kg/m | | 14 mm | - | 138.3 kN | 0.90 kg/m | | 16 mm | - | 180.6 kN | 1.18 kg/m | | 18 mm | - | 228.6 kN | 1.49 kg/m | | 20 mm | - | 282.2 kN | 1.84 kg/m | | 22 mm | - | 341.5 kN | 2.23 kg/m | | 24 mm | - | 406.4 kN | 2.65 kg/m | | 26 mm | - | 477 kN | 3.11 kg/m | | 28 mm | - | 553.2 kN | 3.61 kg/m | ...
