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
A steel wire rope, comprising:
- one or more strands including steel wires;
- and
- a lubricant, the lubricant including an oil and an amount of a powder substance, wherein the lubricant is in a form of paste and the powder substance includes particles having a hardness that is greater than a Mohs Scale hardness of 4.
A traction sheave elevator, comprising:
- an elevator car;
- and
- a plurality of suspension ropes, each suspension rope including one or more strands composed of steel wires, wherein the plurality of suspension ropes are led to pass over a traction sheave, the traction sheave provided with a hoisting machine,
- wherein each suspension rope of the plurality of suspension ropes is lubricated with a lubricant, the lubricant including
- an oil, and
- a powder substance, the powder substance including particles, the particles having a hardness that is greater than a Mohs Scale hardness of 4.
A rope lubricant for a steel wire rope, the steel wire rope including one or more strands composed of steel wires, the rope lubricant comprising:
- an oil;
- and
- a powder substance, wherein the rope lubricant is in a form of paste and the powder substance includes particles having a hardness that is greater than a Mohs Scale hardness of 4.
A method, comprising:
- applying a lubricant to a rope to lubricate the rope, wherein the rope includes metal as a load-bearing material, wherein the lubricant includes at least an oil and a powder substance, wherein the powder substance includes particles having a hardness that is greater than a Mohs Scale hardness of 4.
