The durability of a wire rope is improved. The wire rope includes a rope body having at least one strand each formed with a plurality of element wires twisted with each other; a lubricant interposed between the plurality of element wires of the at least one strand; and a resin layer coating the outer periphery of the rope body along with the lubricant, the lubricant containing a sulfur-containing organic molybdenum compound.

The invention relates to an accessory connector device and to a connection system comprising said device, for connecting and locking at least one accessory to at least one cable, wherein the connector device comprises at least one spiral curved wire whose pitch is between 0.1 and 50 cm, extending and forming an outer envelope and an inner zone surrounded by said outer envelope, wherein the spiral curved wire pitch defines spiral sections, so that the connector device comprises between 1 to 1000 spiral sections along its extension, wherein the inner zone of the connector device comprises a spiral axis, so that the outer envelope formed by the spiral curved wire surrounds said spiral axis, wherein said inner area is configured to receive a first cable arranged along the spiral axis, and wherein at least one of the spiral sections of the spiral curved wire is configured to connect the connector device with the accessory in said at least one spiral section, locking the lateral sliding of the accessory with respect to the spiral axis, so that at least part of the accessory is located between the first cable and the spiral curved wire.

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.

In a paste type lubrication between a steel wire rope and a rope groove of a pulley, is applied a paste lubricant which contains oil and small solid particles. Solid particles could be of a wide variety sizes and they are small enough to at least partly fit into the valleys between the peaks of surface roughness of the ropes or the rope groove.

The method for manufacturing an individually sheathed strand comprises: conveying a group of metal wires through a die; upstream of the die, applying a first filler product to at least a first portion of the strand; upstream of the die, applying a second filler product to at least a second portion of the strand distinct from the first portion; and extruding a plastic around the group of metal wires passing through the die, so as to envelop the group of metal wires covered with the first and second filler products in a continuous sheath formed of the extruded plastic. The second filler product has greater adhesion to the group of metal wires than the first filler product.

A wire rope has a lubricated core, an inner jacket in contact with the core, and outer strands wrapped around the inner jacket. An outer jacket surrounds the outer strands and contacts the inner jacket to form an integrated jacket. A method of forming an integrated jacket for a wire rope in which an inner jacket is cold applied and an outer jacket is applied by application of molten material to the inner jacket.

A wire rope lubricant having a base fluid as a majority component, and a wax or polymer as a minority component wherein at least one of the base fluid and the wax, or polymer, is biodegradable. A method of forming a wire rope having a plurality of wire strands, the method including the step of applying the wire rope lubricant between the wire strands.

The object of the invention is a traction sheave elevator and a steel rope that comprises 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 a steel rope. The lubricant comprises at least oil and powder substance, which powder substance comprises at least particles whose shape substantially spherical or almost spherical, and preferably the hardness of at least part of the particles is greater than 4 on the Mohs scale.
