A passenger ropeway system has a plurality of vehicles mounted on a traction cable for movement between its stations. A hazard detection evaluation unit is connected to cameras and evaluate image data from an exit area to determine the presence of a vehicle and passengers in that exit area. In the event of such presence, when another vehicle enters the exit area or is at a predetermined distance from such entry, an emergency deceleration or emergency stop signal is generated. The signal is used to slow down or stop the vehicle or vehicles directly and automatically without the need for an operator to be present. In addition, image signals from the cameras are transmitted to an operator display device via a signal transmitter so that an operator can restart the ropeway system if necessary.

The invention utilizes a ski lift for wind power generation outside of the ski season. The carriers on the ski lift are replaced by wind catching structures that pull the haul rope either uphill or downhill, depending on the prevailing wind. The haul rope rotates the electrical drive motor of the ski lift, causing it to generate electrical energy.

An aerial ropeway hazard sensing system including a radar sensing unit mounted at a position along a ropeway that generates radar data representative of predetermined ropeway conditions proximate the radar sensing unit, and a processor that analyzes data from the radar sensing unit to detect predetermined hazard conditions and to generate a hazard detection signal indicative thereof. A method of performing an aerial ropeway safety function comprises using radar to detect a hazard condition and generating a hazard detection signal in response thereto; generating a control signal in response to the hazard detection signal; and initiating a safety with the control signal.

A chair for chairlifts includes at least one seat part which can pivot about an axis and an elastic element disposed between the seat part and a frame of the chair. An actuating device that is connected to the seat part allows the seat part to pivot downward counter to the force of the elastic element and lock the seat part in the downward position in order to make it easier for chairlift users to get on and off the chair. A cableway system having at least two stations and the chair as well as a method for pivoting at least one seat part of a chair of a chairlift, are also provided.

A chair for chairlifts includes a pivotal installation that can pivot into a closed position and an open position, a locking element of the installation, and a blocking element for the locking element. The blocking element is movable into a blocking position and into a releasing position. A control element allows the blocking element to be moved from the blocking position and the installation to be opened. A chairlift and a method for activating a pivotable installation are also provided.

The present invention relates to an apparatus for gliding over a body of flowing water, in particular for surfing, waterskiing, kiteboarding and/or wakeboarding, having a first buoyancy body. The apparatus is characterized by a second buoyancy body, which can be connected to the first buoyancy body by means of a cable, and by a pulley mechanism, which has the cable running through it and can be connected to a first stationary object, and therefore the first buoyancy body and the second buoyancy body, by means of the pulley mechanism with the cable running through it, can execute movements in substantially opposing directions on the body of flowing water.
