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.

Ropeway self-propelled transporting equipment, comprising a transporting device (1) which runs along a ropeway rope, wherein the transporting device (1) comprises a sliding adjusting mechanism (2), a transmission mechanism (3) and a pull arm (4); and the sliding adjusting mechanism (2) and the transmission mechanism (3) are movably connected to the pull arm (4) respectively. The sliding adjusting mechanism (2) is arranged on the pull arm (4), and a first transmission component (21), a second transmission component (22) and a third transmission component (23) of the sliding adjusting mechanism (2) enclose a ropeway rope clamping area. When the ropeway rope is positioned in the ropeway rope clamping area, the ropeway rope is clamped to the first transmission component (21), the second transmission component (22) and the third transmission component (23) so that the transporting device (1) may freely slide along the ropeway rope. In addition, a first lifting component (20) is provided on the sliding adjusting mechanism (2). The ropeway rope clamping area may adapt to ropeway ropes of different sizes and smoothly traverse a ropeway rope junction or a ropeway support bend. Therefore, the applicability of the present transporting device (1) is improved.

Provided is a single-drum-type cableway carriage that can also be used for lumber-yarding which involves either the raising of a load or the lowering of a load over gentle slopes and steep surfaces.

The cableway carriage according to the present invention includes: a base member 1; a main cable braking member 10 that has a braking face that comes into contact with the main cable and that is secured to the base member; a first lever 20 that has a first fulcrum serving as a center of rotation and secured to the base member, a first lever braking face provided in a position facing the braking face, a biasing member that biases the first lever braking face in a direction of separation from the braking face, and a drive pulley capable of applying a force in the direction in which the first lever braking face is brought close to the braking face by the tensile force of the rope, and a second lever 30 that has a second fulcrum secured to the base member and serving as a center of rotation, and a first lever pressing part capable of pressing the first lever in the direction in which the first lever braking face is separated from the braking face.

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.

Device for coupling a vehicle to a traction cable, comprising a fastening configured to couple the vehicle to the traction cable, the fastening including at least two rotatable elements configured to occupy a coupling position in which said at least two rotatable elements are in contact with the traction cable and the vehicle is coupled to the traction cable, the device including a variable speed drive configured to modify a speed of rotation of said at least two rotatable elements when said at least two rotatable elements are in the coupling position, so that the vehicle moves relative to the traction cable.

This coupling device comprises a support body, a first clamping jaw, a clamping member comprising a second clamping jaw and a connecting portion, the clamping member being hingedly mounted on the support body between a clamping position in which the first and second clamping jaws are configured to clamp a traction cable; a biasing device configured to bias the clamping member towards the clamping position, and an actuation member configured to actuate a displacement of the clamping member between its clamping and release positions, the actuation member being slidably mounted on the support body between a first stable position in which the clamping member is in the clamping position, and a second stable position in which the clamping member is in the release position.

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.
