An aerial sky tram system includes a plurality of towers, a cable track suspended from the plurality of towers by a support cable, and a sky tram coupled to the cable track. The sky tram includes a plurality of rotors that propel the sky tram along the cable track.

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.

A transport system for carrying a proppant, the system comprising a loading tower, a first transfer tower, a second transfer tower and an unloading tower. The loading tower is located proximate a loading area while the unloading tower is located proximate an unloading area. The system also includes a first transfer tower and a second transfer tower. A first aerial cable conveys a transfer container from the loading tower to the first transfer tower, while a second aerial cable conveys the transfer container from the second transfer tower to the unloading tower. The transfer container is configured to be suspended from the first and second aerial cables en route from the loading tower to the unloading area. Sand or supplies from the transfer container is received at the unloading area for use in a wellbore operation. Methods of transporting sand for use in wellbore fracturing operations are also provided.

A hybrid cable/rail transportation system comprising: at least one portion of the system configured as a cable transportation system; at least one portion of the system configured as a rail transportation system, a first trolley coupled to the supporting cable and comprising a first coupling device for coupling to the cabin; a second trolley coupled to the rail and comprising a second coupling device for coupling to the cabin; a plurality of transportation units wherein each transportation unit comprises a cabin, each cabin comprising a roof provided with a coupling system configured for coupling the cabin to the first trolley along the system portion configured as a cable transportation system and to the second trolley along the system portion configured as a rail transportation system; wherein the coupling system arranged on the roof of the cabin, the first coupling device of the first trolley and the second coupling device of the second trolley are configured for allowing a progressive passage of the cabin from the first to the second trolley, or vice-versa, without stopping the support.

For travel on a cable, the zipline trolley includes a wheel, a brake, a frame, a hanger, and a lower slot. The wheel is disposed on a proximal end of a frame. The wheel includes a groove that receives a cable at a lower portion of the wheel and a wheel bearing. The brake is disposed on a distal end of the frame. The brake is connected to a given lever point and includes a groove along a brake bottom that receives the cable. The frame includes an array of lever points disposed between the brake and the wheel. The hanger is connected to a given lever point and suspends a weight. The weight applies a force about the wheel to the brake to control a rate of descent of the device along the cable. The lower slot receives the cable.

A cable transportation system comprising: at least a cable; an upstream station and a downstream station between which the cable extends; a plurality of supporting intermediate structures for supporting the cable between the upstream station and the downstream station; a plurality of transporting units coupled above the cable in a configuration suspended in the void and free to swing; an alarm device configured for detecting the contact between the transporting units and the supporting intermediate structures when a threshold tilting angle of the transporting units is exceeded and for emitting a relative alarm signal.

A cable car system has at least two cable car stations and at least one carrying cable between the stations. A cable car vehicle is moved by a hauling cable between the car stations. The travelling positions of the vehicle along the travelling route are determined by a measuring device and transmitted to a control unit and processed and stored in same. A signal is input into the control unit by an input device located on a cable car support such that maintenance or assembly works and similar are carried out on this cable car support. When a cable car vehicle approaches the cable car support, the drive for moving the at least one cable car vehicle is controlled by the control unit such that the cable car vehicle is moved at a significantly reduced speed in relation to the operating speed, or is stopped at the cable car support.
