Warum Drahtseile schmieren?

The wire rope is greased internally and externally during manufacture. The grease serves to reduce the damaging friction between the elements of the rope. At the same time the grease prevents corrosion. When the rope is in use, the lubricant is used up, especially on the outside. This causes increased friction in the rope elements which leads to faster wear and tear.

The rope can also be protected from corrosion by galvanising. However, galvanised ropes also have to be lubricated in order to minimise the internal wear and tear which starts with abrasion of the zinc coating.

Bending cycles of a dry rope decrease at higher line pull, whereas with a lubricated rope they stay constant. Ropes which are relubricated with PFEIFER RL in time, can improve the number of bending cycles and their lifetime significantly.
