The cable transportation installation (1) comprises a cable (2) supported by several sheaves (5) of several pillars (4). At least one pillar (4) is provided with at least one optical fuse (6) defining first and second states enabling or preventing flow of an optical signal. A detection device (7,8) is configured to detect derailment of the cable (2) from one of the sheaves (5). The detection device makes a signal flow through the optical fuses (6) to monitor their state. The optical fuses (6) are configured to change state between the first state and the second state when the at least one optical fuse (6) comes into contact with the cable (2) or with one of its supports. The detection device emits an alarm in response to detection of a change of state of one of the optical fuses (6). Each optical fuse (6) comprises an optical fibre.
