Cornering structure and cableway installation comprising this structure

Aerial structure (7) for an aerial cableway system of the type comprising at least one hauling cable, the structure comprising:

• an entry (A) and an exit (D) which are intended to be connected respectively to an upstream section (3A-1;
• 5A-1;
• 9A-1) and to a downstream section (3A-2;
• 5A-2;
• 9A-2), each generally rectilinear, of a transport pathway of the aerial cableway system, as well as an intermediate section that is connected to the entry (A) and to the exit (D), the intermediate section being curved (3A-3;
• 5A-3;
• 9A-3), at least projecting in a horizontal plane, between the entry (A) and the exit (D),
• at least one active vehicle guidance system for guiding, at least laterally, on at least a first portion (A;
• B) of the curved intermediate section (3A-3;
• 5A-3;
• 9A-3), this said first portion (A;
• B) generally extending along a portion of a radioid, or of a pseudo-radioid, at least projecting in the horizontal plane, or a mean plane which contains said entry and said exit, and
• at least one hauling cable guidance system that is active between the entry (A) and the exit (D) and capable of deflecting said cable, at least laterally, between said entry (A) and this said exit (D).
