Lubricated wire rope

A wire rope comprising a plurality of strands of wire rope elements wound around a core strand wherein the improvement comprises a polymeric lubrication medium incorporated in the interstices defined by said strands, with said polymeric lubrication medium having a lubricant incorporated therein such that said lubricant is expelled from said medium when compressive forces are applied to said medium by said strands of wire rope during use of said rope, and said lubricant is drawn back into said medium when said compressive forces are removed from said medium.

A self-lubricating wire rope comprising a plurality of strands of multi-wire wire rope elements wound around a core strand comprising a core element and a lubricant, characterized in that said lubricant comprises a polymeric lubricating medium having a carrier and a lubricant incorporated therein such that said lubricant is expelled from said medium when compressive forces are applied to said medium by said strands of wire rope during use of said rope, and said lubricant is drawn back into said medium when said compressive forces are removed from said medium.

A self-lubricating wire rope comprising a plurality of multi-wire strands of wire rope elements wound around a core strand, each of said multi-wire strands comprising a plurality of wires having a lubricant in the interstices thereof and having a coating of said lubricant thereon, characterized in that said lubricant comprises a microporous polymeric lubricant having a carrier and a lubricant incorporated therein such that said lubricant is expelled from said medium when compressive forces are applied to said medium by said strands of wire rope during use of said rope, and said lubricant is drawn back into said medium when said compressive forces are removed from said medium.

A self-lubricating wire rope comprising a lubricated core including a central strand and a plurality of outer strands wound therearound, a lubricant filling the spaces between said outer strands and extending outwardly only to the extent of the outer diametrical limits of the rope, and a plurality of multi-wire strands wound around said lubricated core, characterized in that said lubricant comprises a microporous polymeric lubricant having a carrier and a lubricant incorporated therein such that said lubricant is expelled from said medium when compressive forces are applied to said medium by said strands of wire rope during use of said rope, and said lubricant is drawn back into said medium when said compressive forces are removed from said medium.
