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.
Claims19
A device for lubricating a multi-strand tensioning cable, the device comprising:
- a body having:
- 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;
- and
- a spreading device for spreading the multi-strand tensioning cable, wherein the spreading device is associated with the lubricant passage and has a main body having a feedthrough opening for receiving the multi-strand tensioning cable, the main body having a plurality of spreading elements arranged to move radially in the main body, each of the plurality of spreading elements having a contour that tapers inwardly in a radial direction configured to engage and produce a gap between respectively adjacent strands of the multi-strand tensioning cable to place the multi-strand tensioning cable in a spread configuration while in the feedthrough passage, wherein the spreading device is configured to return the multi-strand tensioning cable to a twisted configuration.
