ABSTRACT:
A method of lubricating steel cable wherein the steel cable is drawn through a chamber containing lubricant under pressure. The chamber has an outlet and an inlet lined with rubber sleeves through which the cable passes. A liquid lubricant is utilized, preferably a lubricating oil, which is supplied to the chamber by means of a pump having a high delivery pressure, minimum 20 bar and preferably above 40 bar, but with a relatively small delivery capacity. The rate of passage for the steel cable through the chamber is adapted such that the hollow spaces in the steel cable absorb the supplied oil to such an extent that oil leakage is avoided. The apparatus for carrying out the method comprises a chamber for lubricant under pressure, having an inlet and an outlet for the steel cable. A supply hose for lubricant leads to the chamber, and a pressure pump ensures pressure in the lubricant. The pump is a suction pump which can deliver a pressure of at least 20 bar, preferably above 40 bar, but has a small delivery capacity.
