Abstract:
1. A device for measuring a speed of a haulage cable of a cableway, the haulage cable comprising a plurality of wires assembled so as to form a plurality of strands, the strands being helically twined so as to form grooves on the haulage cable and arranged between two successive strands of the haulage cable, and the device including: first and second capacitive distance sensors configured to transmit respectively first and second information signals relative to the distance between the grooves on the haulage cable and the first and second sensors, the second sensor being located at a reference distance from the first sensor, a first determination device configured to determine a phase shift between the first and second information signals and a second determination device for determining a speed information of the haulage cable from the determined phase shift and the reference distance.
