Abstract
A device for spreading a multi-stranded tensioning cable, in particular steel tensioning cables, comprising a main body having a feedthrough opening for the entire tensioning cable, and a number of spreading elements which are arranged radially movably in the main body and each have a contour which is of a configuration tapering inwardly in the radial direction for engaging and producing a gap between respectively adjacent strands of the tensioning cable.
Claims21
A device for lubricating a multi-strand tensioning cable, the device comprising:
- a feedthrough passage for receiving the multi-strand tensioning cable;
- a lubricant passage which opens into the feedthrough passage, wherein the lubricant passage is in fluid communication with at least one pressure generator;
- a spreading device for spreading the multi-strand tensioning cable, wherein the spreading device is associated with the lubricant passage;
- and
- a main body having a feedthrough opening for receiving the multi-strand tensioning cable, the main body having a plurality of spreading elements arranged radially and movably in the main body, each of the plurality of spreading element having a contour that tapers inwardly in a radial direction for engaging and producing a gap between respectively adjacent strands of the multi-strand tensioning cable.

(canceled)
A method of lubricating a multi-strand tensioning cable, the comprising:
- passing the tensioning cable through a feedthrough passage,
- delivering lubricant on to the tensioning cable within the feedthrough passage, and
- spreading the tensioning cable before delivery of the lubricant,
- wherein spreading of the multi-strand tensioning cable comprises:
- passing the tensioning cable through a feedthrough opening;
- moving a plurality of spreading elements radially inwardly within the feedthrough opening so that the plurality of spreading elements engage between adjacent strands;
- and
- produce a gap between the adjacent strands.
