Legend

DT 104, Doppelmayr, torsion bar cable grip, 1993 The gripping process is initiated by means of a lever, the end of which is implemented as a grip jaw. The gripping force is applied by four torsion bars located in the two lateral rotating drums. Because it is available in a range of sizes, this cable grip is very versatile. The cable grip innovation The device attaching the chair or gondola to the cable is the central component of any detachable-grip cableway. The invention of a device capable of gripping as well as detaching itself from the propelling cable opened up a whole new world to the cableway industry. The concept has benefited mountain tourism as well as, more latterly, mass transit systems in cities. The first chairlifts featured chairs that were permanently clamped to the circulating cable, which made getting on and off at a constant speed of around 2 m/s something of a challenge. The detachable grip system allows the vehicle (chair or gondola) to be freed from the cable at the terminus and guides it onto a separate, propelling system travelling at less than 0.8 m/s. While rows of rubber tyre wheels slow the vehicle down, the otherwise free-hanging wheels of the cable grip mechanism run on their own rails in the terminus. When the vehicle's cable grip attaches itself back onto the circulating propelling cable, the vehicle returns to its considerably higher speed of between 4 and 8 m/s. The technology underpinning the detachable grip – now capable of exerting a pressure on the cable in excess of 600 kg – and the terminus circulation system have become increasingly sophisticated. The invention of the detachable grip quickly led to a boom in the chairlift segment. The circulating cableway system, to this day, owes its success as a transportation system to its key component – the detachable cable grip.
