CML SARL (Cameroon Maritime Logistics) is your **one-stop shop for wire rope steel in Cameroon**: steel wire rope, slings, terminations, clips, thimbles, shackles, sockets and lubricants, all available from one supplier in Douala. 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 (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 | | 32 mm | - | 722.5 kN | 4.71 kg/m | | 36 mm | - | 914.5 kN | 5.96 kg/m | | 40 mm | - | 1129 kN | 7.36 kg/m | ### Measuring diameter correctly Always measure across opposite strand crowns ...
