Abstract
The object of the invention is a traction sheave elevator and a rope that contains metal as a load-bearing material, such as the suspension rope of an elevator, which rope comprises at least one or more strands laid from metal wires and which rope is lubricated with a lubricant. Another object is the use of the aforementioned lubricant for lubricating the rope. The lubricant comprises at least oil and thickener, which thickener in the lubricant comprises at least 10% or more of the mass of the lubricant.
Claims14
Rope containing metal as a load-bearing material, which rope comprises at least one or more strands laid from metal wires and which rope is lubricated with a lubricant, wherein the lubricant in the rope comprises at least oil and thickener, which thickener in the lubricant comprises at least 10% or more of the mass of the lubricant.
Traction sheave elevator, comprising at least an elevator car, possibly a counterweight and a plurality of suspension ropes for moving the elevator car, which ropes are led to pass over a traction sheave provided with a hoisting machine and which suspension ropes are lubricated with a lubricant, wherein the lubricant of the suspension ropes of the elevator comprises at least oil and thickener, which thickener in the lubricant comprises at least 10% or more of the mass of the lubricant, suitably approx. 30-85% and preferably approx. 65-75% of the mass of the lubricant.
Use of a lubricant, which comprises at least oil and thickener, which thickener in the lubricant comprises at least 10% or more of the mass of the lubricant, for lubricating a rope, e.g. a steel rope, that contains metal as a load-bearing material.
Rope containing metal as a load-bearing material, which rope comprises at least one strand comprising metal wires and which rope is lubricated with a lubricant, wherein the lubricant in the rope comprises at least oil and thickener, which thickener in the lubricant comprises at least 10% or more of the mass of the lubricant.
Rope lubricant for a steel wire rope, wherein the lubricant comprises oil and fine-grained solid additive that is softer than the steel of the steel wire ropes.
