Experimental results The practical results of the installation of 7 strands rope confirm the suitability of the rope for the scope of reducing vibrations and noise. A Chairlift 34 mm x 1400 m – bright – 2002 – replacement of the old rope B Chairlift 36 mm x 2150 m – galvanized – 2002 – first equipment C Cableway 32 mm x 1740 m – bright – 2002 – replacement of the old rope D Cableway 34 mm x 1740 m – bright – 2002 – replacement of the old rope E Chairlift 30 mm x 2050 m – bright – 2002 – replacement of the old rope F Funicular 33 mm x 1600 m – bright – 2002 – replacement of the old rope G Cableway 32 mm x 1850 m – bright – 2003 – replacement of the old rope H Cableway 35 mm x 1670 m – bright 2004 – Plant revamping I Cableway 35 mm x 3340 m – bright 2004 – Plant revamping J Cableway 25 mm x 3200 m – galvanized 2004 – replacement of the old rope K Cableway 25 mm x 2480 m – galvanized 2004 – replacement of the old rope L Chairlift 42 mm x 2805 m – galvanized 2004 – first equipment M Cableway 27 mm x 2300 m – bright 2004 – Plant revamping N Cableway 24 mm x 2300 m – bright 2004 – Plant revamping
