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.

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.

The arm is movably coupled to the boom for translational and rotational movement relative to the boom. The cylinder includes a first end and a second end, and the cylinder defines an internal bore in fluid communication with the fluid source. The rod is coupled to the arm and is slidably received within the cylinder. The rod includes a port and a passage for providing fluid to the attachment. The port provides fluid communication between the internal bore and the passage. The port is positioned within the internal bore throughout the entire range of movement of the rod relative to the cylinder.

Abstract: An industrial machine that includes a dipper, a dipper handle, a boom, a crowd motor, a hoist motor, a swing motor, a first sensor, a second sensor, and a controller. The first sensor generates a first signal related to a dipper handle angle and the second sensor generates a second signal related to a hoist rope angle. The first signal and the second signal are received by the controller. The controller determines, based on the first and second signals, a retract torque value. The retract torque value is compared to a retract torque threshold values. If the retract torque value is greater or equal to the threshold value, the retract torque of the crowd motor is set to a maximum value. If the retract torque is less than the threshold value, the retract torque of the crowd motor is set to a default value.

Abstract: An industrial machine that includes a dipper, a hoist drum, a wire rope connected between the hoist drum and the dipper, a hoist motor, a sensor, and a controller. The sensor generates a signal related to a number of wire wraps of the wire rope around the hoist drum, which is received by the controller. The controller determines, based on the signal from the sensor, the number of wire wraps around the hoist drum. If the controller determines that there are an insufficient number of dead wraps around the hoist drum, the controller sets one or more parameters of the hoist motor. The controller sets each of the one or more parameters of the hoist motor to a value that is lower than a normal operational value for the parameter.

Abstract: The industrial machine includes a component that includes a first permanent magnet and a second permanent magnet. A circular magnetic sensor array senses a first magnetic flux associated with the first permanent magnet and a second magnetic flux associated with the second permanent magnet. The sensor array includes a first magnetic sensor that senses the first magnetic flux and a second magnetic sensor that senses the second magnetic flux. The controller receives a first flux signal related to the first magnetic flux and a second flux signal related to the second magnetic flux, analyzes the first flux signal to identify a first peak magnetic flux, and analyzes the second flux signal to identify a second peak magnetic flux. The controller then determines the inclination of the component based on the first peak magnetic flux and the second peak magnetic flux.
