Cable lubrication is important for both corrosion protection and friction limitation. For this purpose, greases are required which adhere particularly well to the metal, but which also have the ability to penetrate into the rope core. Their role is to resist the load and thus avoid fretting and false "Brinell effect". Samaro and Molykote™ offer a wide range of special lubricants meeting these criteria.
Wire cables are useful for conveying, towing and hoisting. It is necessary to lubricate them in order to protect them from corrosion and to extend their life. This is because they are subject to various stresses: external environment, jerky sliding, high loads, distortion and friction. Lubrication is carried out by means of adhesive and penetrating lubricants adapted to their composition. Indeed, the formation of a hoisting wire rope is similar to a rope, long, flexible, round, resistant, composed of twisted and/or braided together wires called "strand".
The composition of a rope determines the number and arrangement of strands, wires and core. The composition of the cross-section of the rope shown is: 6 strands of 7 core wires ( 6 x 7 AM wires).
