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 has walls that are foraminous and permit radial flow of a lubricant. The lubricating compound is injected into the channel (18) defined by the conduit. The lubricating material migrates through the orifices in the conduit wall and radially outwardly therefrom.
