  • Publication number: 20130245897
    Abstract: Systems and methods for compensating dipper swing control. One method includes, with at least one processor, determining a direction of compensation opposite a current swing direction of the dipper and applying the maximum available swing torque in the direction of compensation when an acceleration of the dipper is greater than a predetermined acceleration value. The method can also include determining a current state of the shovel and performing the above steps when the current state of the shovel is a swing-to-truck state or a return-to-tuck state. When the current state of the shovel is a dig-state, the method can include limiting the maximum available swing torque and allowing, with the at least one processor, swing torque to ramp up to the maximum available swing torque over a predetermined period of time when dipper is retracted to a predetermined crowd position.

  • Patent number: 8504255
    Abstract: Systems, methods, devices, and computer readable media for controlling the operation of an industrial machine including one or more components. A method of controlling the industrial machine includes determining a position of at least one of the one or more components of the industrial machine during a digging operation, determining a hoist bail pull setting based on the position of the at least one of the one or more components and a relationship between component position and hoist bail pull, and setting a level of hoist bail pull to the hoist bail pull setting. The level of hoist bail pull early in the digging operation is greater than the level of hoist bail pull later in the digging operation.

  • Publication number: 20130195595
    Abstract: A method of controlling a digging operation of an industrial machine. The industrial machine includes a dipper connected to a dipper handle, a hoist rope attached to the dipper, and a hoist motor moving the hoist rope and the dipper. The method includes determining that the dipper is ready to be unloaded, activating a secondary tipping control operation by controlling a speed of the hoist motor, controlling an acceleration ramp rate of the hoist motor, and controlling a deceleration ramp rate of the hoist motor. The method further includes determining when the dipper is unloaded and deactivating the secondary tipping control operation.

  • Patent number: 8359143
    Abstract: Systems, methods, devices, and computer readable media for controlling a digging operation of an industrial machine. A method includes determining a hoist bail pull associated with the industrial machine, determining a crowd torque limit value for a crowd drive based on the determined hoist bail pull of the industrial machine, and setting a crowd torque limit of the crowd drive to the crowd torque limit value to limit a torque associated with a crowd motor to the crowd torque limit value.

  • Patent number: 8355847
    Abstract: Systems, methods, devices, and computer readable media for controlling a digging operation of an industrial machine that includes a dipper and a crowd drive. A method includes determining an acceleration associated with the industrial machine, determining a crowd retract factor based on the acceleration, comparing the crowd retract factor to a threshold crowd retract factor, setting a crowd speed reference and a crowd retract torque for the crowd drive for a period of time based on the comparison of the crowd retract factor to the threshold crowd retract factor.

  • Publication number: 20070107269
    Abstract: A dipper including a dipper door and an impact actuated jaw having a ā€œCā€ shape defining a lip and a chin. The jaw is rotatably mounted on the dipper door for rotation between a door-opened position and a door-closed position and positioned so that when the jaw is in the door-opened position, the jaw chin can be impacted by the dipper body when the door pivots to the door-closed position. The dipper also includes a hold open mechanism for releasably holding the door latch in the latch open position when the latch is in the open position, and a locking mechanism for releasably locking the latch when the latch is in the door-closed position. The locking mechanism includes one bar pivotally attached to the door, and another bar pivotally connected to and extending between each of the one bar and the latch.

  • Publication number: 20050151421
    Abstract: Each crawler shoe comprises a main body having an upper surface, a lower surface, and opposite lateral sides and opposite front and rear sides. Each crawler shoe further includes a mechanism on the main body for articulately and releasably connecting the crawler shoe to an adjacent crawler shoe. Each crawler shoe further includes a roller path on the upper surface of the main body and drive lugs attached to the upper surface of the main body on opposite sides of the roller path. Each crawler shoe further includes an upward extending peening portion so that when a downward force is applied to the peening portion, unrestricted metal flow at the peening portion can occur in a first horizontal direction and in a second horizontal direction greater than 45 degrees from the first horizontal direction. More particularly, the peening portion is greater than 0.1 inch tall, and, in the preferred embodiment, about 0.25 inches tall.
