Abstract: A ground engaging tool locking system includes a pin having a first, proximal head region and a second, distal end region spaced from the first, proximal head region along an axis. The pin includes a groove located between the first, proximal head region and the second, distal end region. A biasing element is disposed at least partially within the groove.

Abstract: An industrial machine that includes a dipper, a crowd actuation device, a hoist actuation device, a swing actuation device, one or more sensors, and a controller. The one or more sensors generate one or more signals related to a load within the dipper. The one or more signals are received by the controller. The controller determines, based on the one or more signals, whether the industrial machine is operating in an over-loaded condition by comparing a suspended load to a suspended load threshold value. If the suspended load is greater or equal to the suspended load threshold value, the controller takes an action to control the industrial machine. The action taken by the controller can include increasing, decreasing, or otherwise modifying a speed parameter or speed limit, increasing, decreasing, or otherwise modifying a force parameter, etc.

Abstract: A system for controlling the operation of an industrial machine during crowd runaway conditions. The system includes a controller that monitors and compares an actual crowd system state (e.g., an actual dipper position) with a requested crowd system state (e.g., a requested dipper position from the operator). If the controller determines that the crowd system is behaving contrary to requested crowd system behavior, the controller adjusts a crowd parameter, such as a crowd motor torque, to resolve the runaway condition.

Abstract: An industrial machine that includes a dipper, a user interface, a sensor, a hoist actuator, and a controller. The user interface is operable to generate a first signal related to a requested characteristic of the industrial machine. The sensor is operable to generate a second signal related to an actual characteristic of the industrial machine. The hoist actuator has at least one operating parameter. The controller is configured to receive the first signal related to the actual characteristic, receive the second signal related to the requested characteristic, compare the requested characteristic to the actual characteristic to detect a dipper drop condition, and modify a setting of the at least one operating parameter of the hoist actuator after the dipper drop condition is detected. The dipper drop condition is detected after the requested characteristic does not match the actual characteristic

Abstract: A method of operating an industrial machine. The method including controlling, via a controller, a movable component of the industrial machine based on a first signal received from an operator control and controlling, via the controller, the movable component of the industrial machine according to an autonomous operation in response to a second signal. The method further including adjusting the autonomous operation to generate an adjusted autonomous operation in response to receiving a third signal from the operator control and controlling, via the controller, the movable component of the industrial machine according to the adjusted autonomous operation in response to receiving a fourth signal.

Abstract: Systems and methods for providing feedback to an operator of an industrial machine. One system includes a controller including an electronic processor. The electronic processor is configured to monitor at least one operating parameter of the industrial machine, determine a plurality of performance metrics based on the at least one operating parameter, and select a subset of the plurality of performance metrics based on a selection criterion. The electronic processor is also configured to display the subset of the plurality of performance metrics to an operator of the industrial machine during operation of the industrial machine.

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.
