Abstract
Device for measuring a haulage cable of a cableway, in particular a chairlift or a cable car, the haulage cable including marks, and the device including first and second sensors configured to transmit respectively first and second information signals relative to the presence of the marks, 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.
