摘要： 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.

摘要： 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.

摘要： A cable car carriage for transporting goods or passengers has two opposing spaced-apart crawlers. Each of the crawlers has a crawler chain composed of juxtaposed chain links. A support cable can be inserted between the opposing crawlers on the opposing chain links of the crawler chains. A pressing mechanism connects the crawlers with one another, and is designed to adjust the distance between the crawlers as well as the pressing force of the two crawlers relative to each other and/or the pressing force of the two crawlers against the support cable. The crawler chains are driven in a circulating movement by a drive via a crawler running gear, thus moving the cable car carriage along the support cable. A cable crane, a passenger gondola, a cable saddle, and a transport assembly employing the cable car carriage are also disclosed.
