Method for the maintenance of a ground-level power supply device for a tram-like vehicle

Method for the maintenance of a ground-level power supply device for a tram-like vehicle The invention relates to a method for the maintenance of a ground-level power supply device (14) for a transport vehicle (16) including: a power supply rail (22); a device (36) for detecting spatial coordinates of a vehicle; and a power supply shoe (32); said device and said shoe equipping a same vehicle (16). The supply shoe includes a vibration sensor (34) and the method includes the following steps: - during the movement of the vehicle along the rail, measuring vibrations of the shoe and simultaneously detecting spatial coordinates of the vehicle; then - comparing measured vibrations of the shoe with a threshold value, and - determining spatial coordinates corresponding to vibrations above said threshold value.
