With Guide Rollers Patents (Class 104/215)
  • Patent number: 5595122
    Abstract: In order to operate both arms of a clamp of a funicular system of a rail and running cable vehicle with the same force and at the same time, a guide carrier element, which includes two longitudinal surfaces over which the free ends of the movable jaws move, is formed in one piece and can move vertically transverse to the free ends so as to be instantaneously and automatically self-centering about the jaws and hence about the clamp.

  • Patent number: 5452662
    Abstract: A device for coupling a ferry, such as a gondola or chair, to the hoisting r load cable of an overhead cableway system includes a clamping body with rollers. A first clamping jaw is rigidly secured. A second clamping jaw can be swiveled relative to the first clamping jaw. The second clamping jaw is located on one end of a two-armed clamping lever on whose other end a control element, such as a cam roller, is provided. When the control elements cooperates with an actuator, such as a cam rail, the clamping lever is pivoted relative to the clamping body counter to the action of at least one torsion spring. That pivoting causes the second clamping jaw to reach its open position. A toggle joint or elbow joint is provided which connects the torsion spring with the clamping lever.

  • Patent number: 4658733
    Abstract: A haul rope grip assembly for an aerial tramway is disclosed which is suitable for both detachable and permanent gripping of the tramway haul rope. The assembly includes a gripping head having a pair of relatively spaced apart converging haul rope gripping surfaces oriented for gravity biasing of the surfaces into wedging engagement with the haul rope under loading of the grip. Additionally, the assembly includes a jaw positioned proximate the surfaces and formed to apply supplemental force to the haul rope in a direction tending to further wedge the haul rope between the gripping surfaces. The jaws are also formed to unwedge the haul rope upon movement from a closed to an open position. In the detachable grip assembly, a pair of independently movable jaws pivotally mounted and actuated by levers are biased closed with leaf springs that are spaced apart to allow for a hold down sheave.
