ABSTRACT:
A method of mounting and tensioning a freely tensioned tension member, particularly a stay cable for a cable-stayed bridge, and a device for carrying out the method, wherein the polyethylene casing of each individual strand is removed during the tensioning process over the length of the extension distance occurring during tensioning at the tensioning end. The peeling tool of the device for carrying out the method is composed of a sleeve having at one end thereof at least one cutting edge, wherein the sleeve surrounds the respective strand over at least an essential portion of the circumference thereof. The sleeve can be positioned in a stationary manner between the anchoring disk and the tensioning press, wherein the strand is pulled through the sleeve during the tensioning process.
