Patent number: 5673625Abstract: A method and apparatus for yarding logs by introducing slack is provided for use with a mono-cable system having a continuous loop of cable strung through a logging area along a path that the harvested timber is conveyed. The invention includes advancing the mono-cable system along the path of the mono-cable system until a length of cable not being used to secure a log is available. Slack is then created in the cable of the mono-cable system, after which the cable is transported to a log located on either side and distant from the path. The choker is then secured to the log, and the hook of the choker is secured to the cable. The slack of the cable is then eliminated, such that the secured log is retrieved from its felled position distant from the path to a position adjacent the path. The cable is then advanced such that the hook of the choker is caught on a stopper of the mono-cable system, and the log is moved along the path to a transport location from which the log is removed from the logging area.Type: GrantFiled: May 26, 1995Date of Patent: October 7, 1997Inventor: Gale Edward Dahlstrom

Patent number: 5224426Abstract: An aerial cableway system for filming subjects in motion over moderate to long distances. An endless cable is tensioned between two support structures in an elongated loop. A cable carriage is suspended from the endless cable and is in contact with both segments of the endless cable at all times. Each segment of the endless cable passes through the cable carriage in opposite directions by wrapping 180.degree. around two drive sheaves for a total cumulative wrap of 360.degree.. Each drive sheave has associated with it a disc brake assembly. The endless cable is driven by a bull wheel mechanism which is located at the base of one of the support structures. As the endless cable is continuously driven the two segments travel in opposite directions. When the disc brakes on one side of the carriage are engaged, the drive sheaves are immobilized on one segment of the endless cable and the carriage is carried along in the direction that the grasped segment of the endless cable is traveling.Type: GrantFiled: November 13, 1991Date of Patent: July 6, 1993Assignee: Cablecam Systems Ltd.Inventors: Jim Rodnunsky, Trou Bayliss

Patent number: 4470355Abstract: A cable tensioning apparatus and method for automatically maintaining and adjusting the tension forces in an endless cable for a ski lift, aerial tramway, etc. is disclosed. The apparatus includes a carriage on which the cable is carried, a pneumatic carriage displacement apparatus in the form of a piston and cylinder, a source of gas under pressure, and a regulator and relief valve connected to establish and maintain a pressure within the cylinder which falls between predetermined minimum and maximum pressures. As the aerial tramway is subject to passenger or cargo loading and ambient conditions which change the tension forces, the pressure in the pneumatic cylinder will vary within the preselected range, and upon a change in the tension force beyond the range, gas is automatically exhausted from or interjected into the pneumatic cylinder to maintain tension forces within the preselected range.Type: GrantFiled: November 14, 1977Date of Patent: September 11, 1984Inventor: Jan K.
