Abstract: A belt-conveying aerial system comprising: a pair of top fixed load-bearing ropes, which are parallel to one another and are set at a distance apart from one another in a transverse direction; a pair of bottom fixed load-bearing ropes; and a belt conveyor comprising a plurality of modules, which are aligned along the load-bearing ropes, are fixedly connected to the load-bearing ropes, and guide a belt for conveying materials; the modules being connected to the load-bearing ropes via an installation vehicle having a supporting top carriage mobile on the top load-bearing ropes, a pair of resting platforms suspended from the top carriage, and, for each bottom load-bearing rope, at least one pair of wheels, which are rotatable in contact with the respective bottom load-bearing rope and are set upstream and downstream of the corresponding module.

Abstract: In a cableway system with supporting and haul cables, a trolley, supporting a passenger car, is moved along two taut supporting cables by a haul-cable drive having two drive pulleys, two return pulleys, and a haul cable wound about the two drive pulleys and return pulleys; the haul-cable drive also having two idle pulleys fitted to the trolley and about which is wound an intermediate portion of the haul cable extending between the drive pulleys, and a retaining device for fixing firmly to the trolley the portions of the haul cable extending from the return pulleys towards the trolley.

Abstract: A blondin cableway installation, comprises a pair of carrying cables extending between the two ends of the installation; a carriage provided with a lifting tackle and supported movably on the carrying cables; a lifting cable for operating the lifting tackle, extending between the two ends of the installation; an outward haulage cable for conveying the carriage along the pair of carrying cables, said outward haulage cable being connected via tackle to the carriage so as to have a pair of outward haulage sections which extend between the carriage and each end of the installation; and a plurality of cradles arranged along the pair of carrying cables and suspended from them in a stationary manner and designed to support the lifting cable and outward haulage cable, each of the cradles comprising, on each side, a pair of support rollers able to receive by means of gravity, alternately, the outward haulage cable or the lifting cable, and a corresponding pair of retaining rollers able to bias the lifting cable and ha
