A mechanical assemblage similar to a traditional zipline, where a wheeled cart travels with the assistance of gravity along a guide cable strung between two points. However, this new system allows the cart to travel further, along multiple segments of guide cable and track, connected to each other by an unique attachment system which allows the cart to travel unabated, from cable to track and back to cable, by allowing the mounting attachments for the track segments to pass through an opening in the side of the cart and then close the opening to make it impossible for the guide cable to escape the cart, while riding on the guide cable. This is the most compact, simple and highly functional solution yet presented for genuine cable and track zipline system able to function with only the potential energy of gravity.

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.

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.

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) 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).

A device replaces roller sets on pylons of cable cars. The device contains a replacing vehicle which can be moved along a cable of the cable car and at least two winches having cables by which the roller set to be replaced can be lowered and a new roller set can be raised. The replacing vehicle contains at least two interconnected vehicles which by way of clamps are connected to the cable.

A circular cableway includes a control on a cableway vehicle and a control guide device in at least one cableway station configured to interact with the control during movement of the cableway vehicle to generate a deflection force to pivot at least one cable clamp of the cableway vehicle transversely to the direction of movement of the cableway vehicle at a fixed deflection angle about a first axis of rotation, wherein the control guide device is arranged relative to an actuating device of the cableway station, which actuating device is provided for actuating the cable clamp to generate the deflection force in a defined temporal relation to the actuation of the at least one cable clamp.

A redirect, being a type of rope management apparatus is disclosed. The redirect includes a sheave assembly that includes a plurality of sheaves disposed for rotation about parallel axes. It also includes a mounting assembly that is suitable for connection to a support. The mounting assembly and the sheave assembly are interconnected by a hinge arrangement such that they can be pivoted with respect to one another about one or more axis that is generally normal to the axes of rotation of the sheaves. The redirect may be used in a rigging assembly, typically in pairs, to perform winching, lifting or traversing operations.

A cable car system includes vehicles that are clamped to a hauling cable along the route and decoupled from the hauling cable upon entering the stations. The vehicles are moved through the stations by control tires which are coupled to one another by gear mechanisms and driven via a supporting pulley for the hauling cable. The control tires are mounted on a supporting frame on at least one supporting structure. The rotation of the supporting pulley that drives the control tires is derived from the hauling cable by way of a drive belt. The drive belt runs over the supporting pulley, which is mounted on a pivotable rocker, and over at least one control tire. The pivotable rocker is mounted on the supporting structure for the supporting frame, or the pivotable rocker is mounted on a supporting structure to which the supporting frame is not attached.

A clamp for a cable-drawn transport device includes clamp jaws having a clamp spine and clamping tongues adjoining the clamp spine. The clamp spine and the clamping tongues form running surfaces for rollers. In the longitudinal direction, the clamping tongues have a substantially S-shaped curved running surface, which merges continuously into the running surface of the clamp spine.
