A system and method to ensure a sufficient amount of electrical energy is supplied to a cable-drawn vehicle of a transportation device. Electrical loads of the vehicle are supplied with power outside a station by an electrical energy store of the vehicle or by both an electrical energy store and the generator during a first movement phase, in which the vehicle is accelerated to a limit speed or, conversely, decelerated from a limit speed into a station. In a subsequent second movement phase, the vehicle is supplied with electrical energy by the generator while the vehicle moves at a speed that is greater than the limit speed.

To simplify the operation of a cableway and at the same time ensure safe operation, it is provided that, in a cableway station, at least one openable safety barrier is provided, wherein a sensor for detecting an opening state of the at least one safety barrier is provided in the cableway station, which sensor transmits a sensor signal to a control unit of a cableway drive as a function of the opening state, wherein the control unit controls the cableway drive as a function of the obtained sensor signal, wherein the control unit is provided to stop the cableway drive or to reduce a drive speed of the cableway drive, when a sensor signal corresponding to an open position of the safety barrier is received, wherein the safety barrier has a remotely-operable actuating unit which can be activated, by means of a remote control unit, to reset the safety barrier from the open position, in which the cableway drive is stopped or the drive speed is reduced, into a closed position, in which the cableway drive can be activated again or the drive speed can be increased again.

Construction 3D printing, although a technology that is expected to provide cost, speed and environmental benefits as compared to the traditional construction practices, suffers from inefficient and often troublesome material delivery by pumping cementitious material through hoses or pipes. The present application addresses the need for a consistent and discrete payload delivery between a source and a moving destination. The invention describes an aerial tram delivery system that provides real-time, on-demand, and discrete transportation of material from a material source to the moving destination printheads of the construction 3D printer. Such discrete delivery of material is applicable and beneficial to other applications as described.

A cable car system has at least two cable car stations and at least one carrying cable between the stations. A cable car vehicle is moved by a hauling cable between the car stations. The travelling positions of the vehicle along the travelling route are determined by a measuring device and transmitted to a control unit and processed and stored in same. A signal is input into the control unit by an input device located on a cable car support such that maintenance or assembly works and similar are carried out on this cable car support. When a cable car vehicle approaches the cable car support, the drive for moving the at least one cable car vehicle is controlled by the control unit such that the cable car vehicle is moved at a significantly reduced speed in relation to the operating speed, or is stopped at the cable car support.

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.

A method and an apparatus monitor the integrity of a wire rope in a wire rope assembly, as well as a wire rope assembly containing such an apparatus. In this case, the wire rope is moved past a sensor device, and a sensor signal is generated with the aid of the sensor device. The sensor signal characterizes a magnetic interaction between the sensor device and the wire rope moving past the sensor device. A measure for the integrity of the wire rope is determined on the basis of the generated sensor signal. Accordingly, the movement of the wire rope is generated here in a normal operation of the wire rope assembly.
