    Abstract: A pressure compensated load sense hydraulic system and method is disclosed where a first pressure compensated valve controls flow between a pump and a first function based on a highest function load; and a second pressure compensated valve controls flow between the pump and a second function based on the highest function load. First and second operator controls activate the first and second functions, respectively. When the first function is stalled and the second function is activated, the controller closes the first valve to remove the first function load from the load sense circuit and prevent flow to or from the first function. The controller can determine the first function is stalled when a timer exceeds an initialization period. When the controller closes the first valve, it can cycle the first valve between a shutoff period where the valve is closed, and a refresh period where the valve is opened.

  • Publication number: 20140079519
    Abstract: An improved clam control mechanism for a mining shovel may offer reduced operator fatigue during excavation operations involving the simultaneous and repetitive manipulation of joysticks and switches. The control mechanism may be configured for the loading and unloading of a shovel having a clam rotatable above the shovel, and may include at least two joysticks adapted for a variety of tasks including fore and aft movements, and angular rotation of the shovel. At least one switch may be adapted for moving the clam automatically between fully open and fully closed positions, such that when the switch is briefly pressed a first way, the clam automatically fully opens, and when a switch is briefly pressed a second way, the clam automatically fully closes. On the other hand, if the switch is briefly pressed during either automatic opening or closing of the clam, any movement of the clam may be immediately halted.

  • Publication number: 20120263566
    Abstract: A system and method for various levels of automation of a swing-to-hopper motion for a rope shovel. An operator controls a rope shovel during a dig operation to load a dipper with materials. A controller receives position data, either via operator input or sensor data, for the dipper and a hopper where the materials are to be dumped. The controller then calculates an ideal path for the dipper to travel to be positioned above the hopper to dump the contents of the dipper. In some embodiments, the controller outputs operator feedback to assist the operator in traveling along the ideal path to the hopper. In some embodiments, the controller restricts the dipper motion such that the operator is not able to deviate beyond certain limits of the ideal path. In some embodiments, the controller automatically controls the movement of the dipper to reach the hopper.

  • Publication number: 20120082536
    Abstract: A motor generator control unit controls operation of a motor generator which generates power using a driving force transmitted from an engine. A charge/discharge control unit electrically connects a first capacitor and a second capacitor and controls charging/discharging of power between the first capacitor and the second capacitor in response to an externally supplied control signal. A motor which is electrically connected to the second capacitor is capable of regenerating electric energy and storing the regenerated energy in the second capacitor. A control device supplies a control signal to at least one of the motor generator control unit and the charge/discharge control unit and reduces a target charging value of at least one of the first capacitor and the second capacitor before the motor regenerates energy.
