Abstract
A wire rope 10 includes a plurality of strands 12. The strands are formed from individual wires or filaments 14. The strands are wound about a central axis. A conduit 16 also extends along said central axis. The conduit 16 has walls that are permeable to a lubricating compound. The lubricating compound is injected into the channel 18 defined by the conduit. The lubricating material migrates through the conduit wall and radially outwardly therefrom to provide lubrication to the individual strands and filaments comprising the wire rope.
Claims12
A wire rope comprising:
- (a) a plurality of multi-filament strands, said strands having interstices between the filaments thereof, wherein said strands engage adjacent strands to form cavities therebetween, the cavities running axially along the length of the wire rope;
- (b) a polymeric jacket disposed about the strands, wherein the polymeric jacket is impeded from substantially entering the cavities by engagement of adjacent strands;
- and
- (c) a compound injected into said interstices of said wire rope.
