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: Methods and systems for operating an industrial machine. One system includes a controller that includes an electronic processor. The electronic processor is configured to calculate an eccentricity of a center of gravity of the industrial machine with respect to a center of a bearing propelling the industrial machine and calculate a ground pressure associated with the bearing based on the eccentricity of the center of gravity. The electronic processor is also configured to set a maximum torque applied by an actuator included in the industrial machine to a value less than an available maximum torque based on the eccentricity of the center of gravity and the ground pressure.

Abstract: A mining machine includes a boom, a handle coupled to the boom, and a dipper coupled to the handle. The mining machine further includes a liner system coupled to the dipper. The liner system includes a first guide member and a second guide member coupled to a surface of the dipper, wherein the first and second guide members and the surface of the dipper define a channel extending along the dipper, and wherein the liner system further includes an insert disposed at least partially within the channel that is inhibited from moving away from the surface of the dipper by a portion of the first guide member.
