Abrégé

A cable transportation system cable return pulley (1) has a hub (3), which is configured to rotate about an axis of rotation (A) and has a plurality of lateral coupling sides lying along respective coplanar straight lines (a, b, c; a, b, c, d; a, b, c, d, e; a, b, c, d, e, f) crosswise to the axis of rotation (A); and a main body (4), which is coupled to the hub (3), has an annular seat (6) for housing the cable, and a number of sectors (20) equal to the number of lateral coupling sides of the hub (3), and wherein each sector (20) is coupled to the hub (3) and to the adjacent sectors (20) solely along two of the straight lines (a, b, c; a, b, c, d; a, b, c, d, e; a, b, c, d, e, f).

Abrégé

A cable transportation system with at least one haul cable has a supporting structure (4) with a tubular portion (9) defining an axis of rotation (A); a pulley (5) extending about the axis of rotation (A); and a bearing assembly (14), which is connected to the pulley (5) and the tubular portion (9) to allow the pulley (5) to rotate about the axis of rotation (A) with respect to the supporting structure, and has a first and second bearing (17, 18) arranged concentrically and in series, so as to ensure rotation of the pulley (5) about the axis of rotation (A) and with respect to the supporting structure (4) by means of at least the first or second bearing (17, 18).
