Disclosed is a steel wire rope for conveyor belts. The steel wire rope includes a central steel wire, a steel wire layer externally wound on the central steel wire, and a plurality of external steel wire strands. Each external steel wire strand includes a core steel wire and N external steel wires. The central steel wire, the steel wire layer externally wound on the central steel wire, and the plurality of external steel wire strands are wound into a steel wire rope for conveyor belts in one step. The steel wire layer is externally wound on the outer side of the central steel wire, the external steel wire strands are wound to wrap the outer side of the steel wire layer, and the external steel wire strands are in line contact with the steel wire layer.

Disclosed is a method for producing a high strength synthetic strength member containing rope and a resultant rope, comprising multiple layers of twisted and braided yarns, wherein individual sheaths enclosing individual strands are of a material such as HMPE, PTFE or UHMWPE with a lower decomposition temperature than the material of said strands being aramid, the method comprising subjecting parts of the rope to heat and tension thereby pre-stretching and creating a non-uniform or non-round shape of said strands, further choosing a combination of braid and twist angles as well as braid compressive forces to accommodate specific strength and elongation relation between the individual rope layers.

Disclosed is a non-steel strength membered high strength cable easily monitored for heat and elongation comprising a length of a core-cable (10), the length of core-cable (10) including at least two fiber-optic conductors (2) that are: (i) disposed in a helical shape; and (ii) completely encased in a solid, flexible material.
One fiber-optic conductor capable of transmitting at least Raman backscattering and the other fiber-optic conductor capable of transmitting at least Brillouin scattering. A combination of the cable (10): (i) with an interrogator that can read and interpret Raman backscattering coupled to and communicating with the fiber optic conductor that is capable of transmitting at least Raman backscattering; and (ii) another interrogator that can read and interpret Brillouin scattering coupled to and communicating with the fiber optic conductor that is capable of transmitting at least Brillouin scattering;
permits ascertaining the elongation of the cable, without using loose tube fiber-opticplacement.

Disclosed is a method for producing a high strength synthetic strength member containing rope and a resultant rope that has greater resilience to high heat temperatures resultant of use with powered blocks and/or sheaves and has a longer service life in comparison to known synthetic rope constructions. The rope of the present disclosure has multiple distinct synthetic substances each forming distinct components that work together to, surprisingly, increase tolerance to bending fatigue of the rope and especially to high heat temperatures resultant of use with powered blocks and/or sheaves in comparison to known synthetic ropes.

A wire rope for face shovels or draglines, comprising: a core, said core is made from a plurality of core strands a plurality of outer strands laid on said core, a plurality of separator strands located in the interstices between said core strands and said outer strands, a plastic jacket around said plurality of outer strands, said plurality of separator strands and said core strands, wherein said plurality of separator strands extend from said core strands and in-between each pair of said plurality of outer strands so as to produce and maintain gaps between said pair of said plurality of outer strands; wherein said core strands are compacted, and the gap between said core strands is less than 0.4% of the diameter of the core strand.
