  • Patent number: 3980158
    Abstract: A brake apparatus with variable braking force for cable cars having a brake mount or housing connectable with a cable car by a connection shaft and including at least one pressure released catch brake. The catch brake has brake jaws which can be applied with a predetermined brake pressure to a guide track of the cable car, and a brake release for releasing the brake jaws in counter action to the brake pressure. Also provided is a first brake release pressure generator connected with the brake release, an actuable brake applying device connected with the brake release; at least one brake force measuring device coupling the brake mount with the connection shaft for ascending travel of the cable car and at least one other brake force measuring device coupling the brake mount with the connection shaft for descending travel.

  • Patent number: 3934517
    Abstract: A cable connection with slack cable-brake release for an aerial cableway, wherein a traction cable and possibly a counter cable are secured to the travelling mechanism or carriage of the aerial cableway and a brake mechanism of the aerial cableway is automatically released by a brake release mechanism influenced by the cable traction upon decrease of the cable traction to a predetermined minimum value. The tensioned or traction cable is guided over a damping mechanism arranged at the travelling mechanism for overcoming the oscillations of the cable and after wrapping about a cable drum is attached to the travelling mechanism. The traction cable in an oscillation-free range is deflected by a force measuring device which for a predetermined value of the cable-contact force which is proportional to the cable traction brings about the response of the brake release mechanism.
