The vehicle comprises a chassis (50) defining a median longitudinal vertical plane that rests on at least one pendulum running gear, comprising two independent lateral pendulum devices (60) situated on either side of the median longitudinal vertical plane, wherein each lateral pendulum device (60) comprises a secondary pendulum (62) articulated in relation to the chassis (50) around a horizontal secondary pivot axis and two primary pendulums, each articulated in relation to the secondary pendulum (62) around a horizontal primary pivot axis, wherein the primary pivot axes of the two primary pendulums are spaced apart from one another longitudinally on either side of the secondary pivot axis, wherein each primary pendulum is associated with at least two support rollers designed to run on the railway track (14), each rotating around a rotation axis parallel to the primary pivot axis of the associated primary pendulum and situated longitudinally on either side of the primary pivot axis of the associated primary pendulum.

A funicular intended particularly for transporting heavy loads between an upstream station (10) and a downstream station (12), comprises a track (14), preferably a railway, connecting the upstream station (10) to the downstream station (12), a vehicle (16) running on the track (14) and at least one towing cable (30) in closed loop having a first towing section (32.1) passing over a first pulley (20.1) of the upstream station and over a first return pulley (26) fixed to the vehicle (16) and a second towing section (32.2), in all ways separate from the first towing section and passing over the return pulley (26) and over a second pulley (20.2) of the upstream station (10).

Articulation for a supporting and guiding device for a vehicle hauling cable of a transport installation, including a first frame adapted to be attached to a support carrying a rotary roller intended to be in contact with the hauling cable, a second frame adapted to be introduced into an orifice formed within a carrying structure of the device, and at least one elastic element placed between the first and second frames and adapted to allow a pivoting movement of the first frame relative to the carrying structure, the articulation having a variable outer diameter able to decrease when the articulation is introduced into the orifice.

Installation of aerial transport, including a hauling cable, a travel path having a first segment equipped with two carrying cables extending along the hauling cable, and a vehicle having an attachment device configured to attach the vehicle to the hauling cable and two pairs of rotary sheaves configured to run on the carrying cables, the travel path having a second segment equipped with two rails extending along the hauling cable, and the vehicle having two pairs of wheels configured to run on the rails.

A circulating conveyor includes a circulating guide section forming a closed loop, a first switchable guide element displaceable between a closed position, connecting a first entry guide section in an entry area of the first conveying section to the circulating guide section, and an open position, a second switchable guide element displaceable between a closed position, connecting a first exit guide section in an exit area of the first conveying section to the circulating guide section, and an open position, a third switchable guide element displaceable between a closed position, connecting a second entry guide section in an entry area of the second conveying section to the circulating guide section, and an open position, and a fourth switchable guide element displaceable between a closed position, connecting a second exit guide section in an exit area of the second conveying section to the circulating guide section, and an open position.

A power supply system comprising a track, which defines a trajectory, wherein the track comprises a track segment terminating at a segment end in a forward direction of the trajectory, and a hood, which is arranged in the extension of the track segment along the trajectory in the forward direction beyond the segment end; while a stringer, which supports the track segment, extends along the trajectory and terminates with a cut end in the forward direction. According to the invention, the system further comprises a reinforcing piece, which is applied against the cut end, in order to extend the stringer in the forward direction, wherein the reinforcing piece is essentially made of plastic and supports the hood.
