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.

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 trolley for supporting transporting units of a transportation system, wherein the transporting units are supported suspended from a guide defining a direction of movement; the trolley comprising: a frame; rolls supported by the frame and configured for resting and rolling on the guide; a suspending arm for supporting the transporting units, wherein the suspending arm pivots constrained to the frame about the direction of movement between a first and a second angular position; a rotation limiting device selectively operable for limiting or blocking the rotation of the suspending arm with respect to the frame.

A funicular intended particularly for transporting heavy loads between an upstream station (10) and a downstream station (12), comprises a railway track (14) connecting the upstream station (10) to the downstream station (12) and a vehicle (16) running on the track (14) and drawn by at least one towing cable (30). 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) each comprising a secondary pendulum (62) articulated in relation to the chassis (50) and two primary pendulums, each articulated in relation to the secondary pendulum (62). Each lateral pendulum device (60) comprises a plate (64) connected to the chassis (50) via one or several jacks (66) to which the secondary pendulum device (62) is articulated.

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).

Transport vehicle designed to be pulled by an overhead cable, including an attachment device configured to attach the vehicle to the overhead cable, a support structure configured to support at least one chair, and a hanger arm connecting the support structure to the attachment device, said at least one chair being mounted rotationally on the support structure.

A cable trolley adapted to transport a user and allow evacuation of the user at an elevation from a ground level, the cable trolley including a connecting member; a carrier configured for accommodating the user, the carrier comprising an opening configured for access by the user and the connecting member is configured to connect the carrier at a first end of the connecting member to a transport structure at a second end of the connecting member; an elongated member configured to be attached to the connecting member at a first end of the elongated member; and a cable, wherein a first end of the cable is configured to be attached to a second end of the elongated member and a second end of the cable is configured to substantially reach the ground level.

Emergency egress systems carry multiple riders simultaneously accessing a zip line (catenary) from higher, accessible, working locations to lower, safer areas in a marine environment. Hangers above the track line suspend trolleys to avoid weighting the catenary unduly at the high end, which might otherwise alter (reduce) clearance distances and safety of riders above a launch platform (deck). Catenary shape is controlled against approaching the launch deck by sequencing the release from the hangers of each trolley to roll along the catenary with its own rider. Track line systems installed may be left undeployed indefinitely. Deployment of a track line will typically be fully effected at the time of egress, adding time but eliminating permanent obstructions that would result if a permanent deployment of track lines were undertaken. Terminal ends are anchored and configured to accommodate workers arriving after escape.
