ABSTRACT:
The invention deals with a cable tensioning system for elevators with separate drive cable and support cable lines 10, 11, which both engage at an elevator cabin 12 and also at a counterweight 13, characterized in that the cable tensioning system comprises a rocker 20 configured as a lever and supported at the counterweight 13 or the elevator cab 12, at which rocker the support cable 11 and the drive cable 10 are fastened to be spaced from each other, that the spacing ratio a:b of the attachment points 31, 32 of the cable lines 10, 12 at the rocker 20 from the support point 21 of the rocker 20 at the counterweight 13 or the elevator cab 12 define the cable tension or pull ratio required for the driving capacity.
