A system for growing plants includes an elevated track circuit comprising two straight track sections and two arcuate track sections, with the straight track sections each including a cavity. A plurality of wheeled trolleys that each include a wheel configured to roll within the cavities and each include a shaft extending downwardly form the wheel. A drive system is configured to move the wheeled trolleys along the track circuit with the wheeled trolleys connected together by a cable, and with the shafts of the trolleys configured to support plants coupled thereto to selectively move the plants along the track circuit. Uses of the system include for growing produce of vine plants in a lean-and-lower manner, or transporting hanging plants through an irrigation device of the system.

An inclined shaft continuous feeding system for solid backfilling materials includes a surface loading system, an inclined shaft transportation system, and a downhole unloading system. The inclined shaft transportation system is arranged between the surface loading system and the underground unloading system. The inclined shaft transportation system includes a bottom unloading dumper, support guide wheels, a guide rail, a drive wheel, a reverse wheel, and a traction steel wire rope configured between the drive wheel and the reverse wheel. The present invention can realize a steady, continuous and efficient transportation of the solid backfilling materials from the surface to down hole. Moreover, the material transportation system does not wear easily, has long service life and low material transportation cost.

A wire drive conveying apparatus is configured to cause a conveyance bogie to run along a guide rail by pulling a wire placed along the guide rail and formed to be endless when the opposite ends of the wire are connected to the conveyance bogie configured to slidably engage with the guide rail. The wire drive conveying apparatus includes: a movable trestle connected to a moving pulley configured to support the wire; a weight configured to pull the trestle in a direction in which a tensile force is given to the wire; a spring provided between the conveyance bogie and the trestle; and a locking mechanism configured to permit a movement of the trestle in the direction in which the tensile force is given to the wire and to prevent a movement of the trestle in a direction in which the wire is loosened.

A track system on which a skater dolly can roll, comprising one or more pairs of rails and one or more rail clamps. Each rail clamp supports one or two pairs of rails. Rails held side-by-side are parallel to each other. Rail clamps can also secure two rails in end-to-end configuration. The distance between rails can be about 5/16 of an inch. The track system can include a skater dolly, the load-bearing wheels of which are angled 20-30 degrees away from vertical to provide clearance past the rail clamps. The skater also has stabilizing wheels that are approximately perpendicular to the load-bearing wheels, and which secure the skater to the rails when the skater is in a non-upright e.g. upside-down orientation. The system can include a motor pulley system that moves the skater along the rails.

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.
