Abstract
A wire rope is disclosed that comprises metal wires, preferably steel wires, as a load-bearing material, which rope comprises at least one or more strands laid from said metal wires and which rope is lubricated with a lubricant. Another object is the use of the aforementioned lubricant for lubricating a steel rope. The lubricant comprises at least oil and powder substance, which powder substance comprises at least particles whose hardness is greater than 4 on the Mohs scale. A traction sheave elevator comprising such a wire rope as a suspension rope is disclosed, too.
Claims24
Steel wire rope comprising one or more strands composed of steel wires and a lubricant, which lubricant comprises oil and an amount of a powder substance, wherein the lubricant is in a form of paste and the powder substance in the lubricant comprises particles whose hardness is greater than 4 on the Mohs scale.
Traction sheave elevator, comprising at least an elevator car, possibly a counterweight and a plurality of suspension ropes, comprising one or more strands composed of steel wires, which ropes are led to pass over a traction sheave provided with a hoisting machine and which suspension ropes are lubricated with a lubricant that comprises at least oil, wherein the lubricant of the suspension ropes comprises powder substance, which powder substance comprises particles whose hardness is greater than 4 on the Mohs scale.
Rope lubricant for a steel wire rope, which rope comprises one or more strands composed of steel wires, and which lubricant comprises oil and powder substance, wherein the lubricant is in a form of paste and the powder substance in the lubricant comprises particles whose hardness is greater than 4 on the Mohs scale.
Use of a lubricant for lubricating a rope, e.g. a steel rope, that comprises metal as a load-bearing material, which lubricant comprises at least oil and powder substance, which powder substance in the lubricant comprises particles whose hardness is greater than 4 on the Mohs scale.
