Wire rope lubricants prevent corrosion, reduce the need for maintenance and hence decrease the costs. Wire rope corrosion can be external and internal, and it often is caused by humidity, alkaline waters, acids, fumes and abrasive environments in general. Lubricated wire ropes’ durability is almost six to eight times longer than not-lubricated wire ropes’.
Wire rope lubricants are divided into two categories: penetrating and coating. There is a petroleum solvent in penetrating lubricants which carries the lubricant into the core of the wire rope and then evaporates, leaving a heavy lubricating film behind to lubricate each strand. Coating lubricants penetrate partially, seal the outside of the cable and reduce the wear and corrosion of external surfaces.
