**For all your wire rope steel needs in Cameroon, one address: CML SARL.** From a few metres of thin galvanized cable to large reels of crane rope, Cameroon Maritime Logistics in Douala answers every request with the right product and fast service. How strong is a 16 mm wire rope? Which diameter do you need for a 5 tonne load? This article answers these questions with tables and the selection method used by CML SARL. ### How to select the diameter The basic rule is: **Minimum breaking load required = maximum line pull x design factor**. The line pull depends on the load, the number of falls and the efficiency of the sheaves. The design factor depends on the application and the applicable regulations. Finally, the rope must fit the drum grooves and sheaves of your equipment. ### Indicative Minimum Breaking Loads (6x19) | Diameter | Min. breaking load, FC, grade 1770 | Min. breaking load, IWRC, grade 1960 | Approx. mass (IWRC) | | --- | --- | --- | --- | | 8 mm | 37.4 kN | 44.7 kN | 0.26 kg/m | | 10 mm | 58.4 kN | 69.8 kN | 0.40 kg/m | | 12 mm | 84.1 kN | 100.5 kN | 0.58 kg/m | | 14 mm | 114.5 kN | 136.8 kN | 0.78 kg/m | | 16 mm | 149.5 kN | 178.6 kN | 1.02 kg/m | | 18 mm | 189.2 kN | 226.1 kN | 1.30 kg/m | | 20 mm | 233.6 kN | 279.1 kN | 1.60 kg/m | | 22 mm | 282.7 kN | 337.7 kN | 1.94 kg/m | | 24 mm | 336.4 kN | 401.9 kN | 2.30 kg/m | | 26 mm | 394.9 kN | 471.7 kN | 2.70 kg/m | | 28 mm | 457.9 kN | 547 kN | 3.14 kg/m | | 32 mm | 598.1 kN | 714.5 kN | 4.10 kg/m | | 36 mm ...
