  • Patent number: 7207277
    Abstract: Embodiments of the invention move objects throughout two-dimensional space by using a support rope that is coupled with both opposing sides of the platform. This rope controls the Y-axis motion and Z-axis motion of the platform and is designated the YZ movement rope. Displacing a portion of the YZ movement rope allows vertical displacement of the platform to be traversed. There is no need for a complex computer control system since the Z-axis displacement is substantially independent of horizontal movement over a coverage area serviced by the platform. In addition, since the rope is commanded from one point, distantly located motors and electrical cables are not required. Many types of useful devices may then be attached to the platform including devices that require external power or devices that possess their own power and are operated via wireless signals.

  • Publication number: 20040206715
    Abstract: Embodiments of the invention move objects throughout three-dimensional space. This is accomplished with two highlines which support skates that move along the highlines. The skates support a three sheave device which in turn supports a platform. The entire system is driven in three dimensions by a Y movement rope pair and an XZ movement rope. The Y movement rope pair moves a skate on each highline in the Y-axis direction. The X-axis and Z-axis motion of the platform is controlled by a single XZ movement rope. Increasing the deployed length of the XZ movement rope causes the platform to lower in the Z-axis direction, while decreasing the deployed length of the XZ movement rope causes the platform to rise. For embodiments that employ equal length highlines in a parallel configuration, there is no need for a control system since the Z-axis displacement is independent of X and Y-axis movement.

The running skyline has an intermediate suspended support consisting of a hanger bar with a shoe pivotally connected to the lower end of the hanger bar by a transverse shaft. The shoe has supporting sheaves and an enclosure rail, with the skyline haulback line supportingly received between the rail and the sheaves. The carriage is open on one side so as to be able to pass the transverse shaft of the intermediate suspended support. The open side of the carriage has a yieldable safety gate which allows the carriage to pass the transverse shaft but which retains the haulback line within the carriage. The lower portion of the carriage has respective sheaves for a slack pulling line and a log suspension line to which logs to be transported are connected. A mainline extends between the yarder and a junction member connected to both the slack pulling line and the log suspension line.

  • Patent number: 4164289
    Abstract: A logging carriage is mounted by hinged sheaves for travel along an elevated cable for the conveyance of felled logs to a log unloading site. The carriage is moved in one direction along the elevated cable by an in haul line which is attached at one end to a powered drum in a yarder. The carriage is moved under the force of gravity in a second direction. The other end of the inhaul line is attached to a spring powered rotatable drum structure mounted on the logging carriage. A drop line for raising and lowering felled logs is mounted on a portion of the spring powered rotatable drum. The spring powered rotatable drum structure is actuated by a compressed air actuated brake assembly. A clamp assembly is mounted on the logging carriage and is selectively engageable with the elevated cable to lock the logging carriage in a preselected position along the cable. The clamp and brake assemblies are controlled by solenoid valves and a radio receiver mounted on the logging carriage.

  • Patent number: 4140227
    Abstract: Method and apparatus for transporting pipe between spaced locations comprising a cable disposed in proximity of the two locations which supports a pipe receiving trough so that the trough can be moved by the cable to enable a pipe supported therein to be transported between the two locations. The tension in the cable is adjusted to enable the trough to be moved in a vertical plane. In one of the embodiments, the trough is directly attached to and moved with the cable. Longitudinal motion imparted into the cable causes the trough to move from one location to the other carrying the pipe therewith. The cable is slackened to vertically move the trough so as to enable the pipe to be placed within or removed from the trough. In another of the embodiments, the trough is attached to spaced carriages which are slidably supported from the cable. A pilot cable attached to the trough enables the trough to be moved longitudinally of the cable to enable transportation of the pipe between the spaced locations.

  • Patent number: 4136786
    Abstract: A rigging arrangement and yarder are disclosed for yarding in which a single cable is used. This cable is anchored at a main storage drum on a yarder and preferably at an anchor in the vicinity of the tail block. The single line serves as a running skyline for supporting a carriage and includes several loops around a tram drum and an idler drum (but only one layer on said drums) which operate to hold cable or to reel equal amounts of cable in or out to both the yarder side and the anchor side of the carriage to move the carriage without introducing slack into either side. Since only a single layer of cable is wound on the tram and idler drums, no energy is lost dealing with varying speeds and torques caused by changing effective diameters, thus saving energy and weight of equipment.

  • Patent number: 3973680
    Abstract: Apparatus for erecting a prefabricated section building having two masts centered on either side of its foundation, the sections transported to loading areas adjacent and between each mast and the foundation. Cables connect the masts and support two independently operable trolleys between the masts, a hoist on each trolley including a cable connects via a yoke to a section in the loading area and lifts same vertically from a truck therein to at least the story being assembled, and then moves it horizontally to immediately above its ultimate location where it is lowered. A nearby operator, by remote control depending from the trolley, controls its movements to position it precisely, such control being of winches connected to cables for moving the hoist and trolleys. This operator also communicates with the ground by telephone or radio. Each mast has three stays. To raise it, it is laid out horizontally with the cables and stays positioned.
