Patent number: 8190288Abstract: The invention describes a method and a position control system (22?) for controlling operation of a computer-controlled load handling device, with a displacement drive for a displacement unit, a lift drive for a vertically displaceable lifting unit and an actuator drive for a loading and unloading device, and a computer predefines a target position for the displacement and lifting units and loading and unloading device and controls the travel to it. Time-minimized reference trajectories are set first of all, optimized with respect to the maximum permissible loads of the load handling device and with respect to the displacement between the start and target positions, and from these, the desired trajectories are calculated for desired positioning forces (Fxsoll, Fysoll, Fzsoll) of the displacement and lifting units and the loading and unloading.Type: GrantFiled: March 2, 2006Date of Patent: May 29, 2012Assignee: TGW Mechanics GmbHInventors: Markus Rohrauer, Rainer Obwaller

Patent number: 7913930Abstract: A spray linkage (10) for a crop sprayer includes a support (16) and a central frame (18) pivotally connected to the support (16), the central frame (18) being pivotable about an axis (32) from a neutral position. At least one hydraulic cylinder (34, 36) is fastened at one end to the support (16) and at the other end to the central frame (18). To damp the spray linkage (10) during oscillating movements, at least a first hydraulic cylinder (34, 36) has a first and a second hydraulic chamber (44, 46, 48, 50), a first hydraulic line (52, 54) is provided which discharges into the first hydraulic chamber (44, 46) and a second hydraulic line (54, 52) is provided which discharges into the second hydraulic chamber (48, 50). Restrictor structure (58, 60, 62, 64) throttles hydraulic flow from a hydraulic chamber (44, 46, 48, 50) while hydraulic flow into a hydraulic chamber (44, 46, 48, 50) is relatively unthrottled.Type: GrantFiled: November 26, 2008Date of Patent: March 29, 2011Assignee: John Deere Fabriek Horst B.V.Inventors: Hans Andre Johan Theeuwen, Petrus Johannes Maria Fransen, Kent Alvin Klemme

Patent number: 7845087Abstract: A magnetically damped inclinometer has a shaft with attached pendulum that rotates. The rotation causes an index member to rotate past one or a set of magnets or electromagnets that are connected to the load. The magnet or electromagnet may be mounted directly to the load or it may be in the form of an off center ring. Another embodiment uses a spring to bias two magnets apart. A cam is attached to the shaft such that, as the pendulum and shaft rotate, a roller connected with the load or spreader bar allows the spring to push the magnets farther apart. The damped inclinometers are used to determine and provide information to respond to the initial sway of a load prior to bringing the load to a stop.Type: GrantFiled: July 8, 2008Date of Patent: December 7, 2010Inventor: Larry A.
