For A zip line trolley brake system includes a cable suspended between upper and lower support platforms which, together, function with rider harnessing, loading, and take-off with a passive braking trolley allowing a controlled descent and barrel spring system providing addition braking near the end of a cable termination. The zip line trolley positioned atop a cable includes a frame assembled from a pair of parallel side plates, a four-sided rotational brake pad, and a parabolic groove wheel which is sandwiched between side plates, and a lever. A lever from which a rider is suspended, can be pinned anywhere within the trolley's circular toothed slot instilling a brake force for the cable slope. A trolley brake generally square sides are grooved for cables and fabricated from a durable polymeric material is rotatably within affixed side plates. A spring system includes a football-shape springs, spring spacers, bump spring spacer receiver, and a locking inserts designed to fasten the springs and allow the springs to collapse within themselves reducing the compression length. A bump spring spacer receiver makes contact with the zipline trolley further decelerating the suspended rider as contact is made with the springs.

An aerial transportation installation is provided with a carrier vehicle and a terminal. The terminal comprises a moving device to move the carrier vehicle in the terminal. The moving device defines a running path of the carrier vehicle and moves the vehicle. A platform is arranged on one side of the running path. The platform allows movement alongside the moving device and enables an operation to be performed on the moving device. The terminal defines a running space for a grip of the carrier vehicle. The moving device is arranged between the platform and the running space. An additional platform is movable between first and second positions. In a first position, the additional platform does not form an obstacle to progression of the vehicle. The second position enables maintenance to be performed on the moving device.

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. 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.

Provided are a suspension device of a monorail crane and a monorail crane. The suspension device includes a suspension box and at least one set of suspension wheels; the suspension box is provided with a receiving groove for receiving at least one set of the suspension wheels; the receiving groove is provided with a first suspension wheel and a second suspension wheel; a first gap is formed the first suspension wheel and the second suspension wheel; the monorail includes at least a first track on which the first suspension wheel is placed and a second track on which the second suspension wheel is placed; a spacer is provided between the first track and the second track; the first gap can accommodate at least the spacer; the suspension devices each further includes a braking mechanism fixed to the suspension box.

An apparatus for moving ropeway vehicles in a ropeway system includes at least one conveying wheel being adjustable in height relative to the vehicles by a lifting device to be brought into abutment against the vehicles for displacing the vehicles along a track using the conveying wheel. An electric lifting device has an electric drive motor with a threaded sleeve or the like to be retained in its height position and rotated by the drive motor and a lifting spindle to be adjusted in height by the threaded sleeve for adjusting the conveying wheel in height. Upper and lower end surfaces of the threaded sleeve and the lifting spindle have stops located approximately in planes normal to the direction of rotation of the threaded sleeve or the like which, in upper and lower end positions of the lifting spindle, abut one another preventing further rotation of the threaded sleeve.

A cableway having at least one cableway station and having at least one cableway vehicle movable between cableway stations with a hauling cable, wherein a control unit is provided for controlling the cableway, the cableway including a limiting device configured adjacent an entry region of the cableway station and operable to limit a lateral pendulum movement of the cableway vehicle as the cableway vehicle enters the cableway station; at least one movable detection element adjacent the cableway station; a detection unit associated with the at least one movable detection element and configured to detect a measured variable associated with a deflection of the detection element and transmit a corresponding signal to the control unit, and wherein the control unit is configured to receive the corresponding signal and control the cableway as a function of the detected measured variable. An associated method for operating a cableway is also described.
