Legend

VH 300, Von Roll/Habegger, 1982 Due to the company’s acquisition, the last cable grip development by Habegger Thun was manufactured by Von Roll, such that the prefix VR (Von Roll) became VH (Von Roll-Habegger). The lever of the dead-point grip developed by Habegger for Flims-La Siala could theoretically adopt a position between open and closed that had no effect, which led occasionally to compliance issues in neighbouring countries. 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.
