ABSTRACT:
A terminal station of an aerial rope transport installation is equipped with a generator (26) of a high-frequency signal modulated in amplitude by the information to be transmitted. This generator (26) is coupled to the looped rope (10) by a transformer (30) which induces a current in the looped rope forming the secondary winding. The cars (20) are equipped with an autonomous receiver (48) which detects the magnetic field generated by the current induced in the looped rope and restores the information transmitted by the rope.
