VIRTUAL FIELD-BASED TRACK PROTECTION FOR A MINING MACHINE
Embodiments described herein provide systems and methods for preventing and mitigating collisions between components of an industrial machine. The industrial machine includes an electronic controller, having an electronic processor and a memory, that is configured to receive dipper position data indicative of a position of the dipper and determine a distance between the dipper and tracks of the industrial machine based on the dipper position data. The electronic controller is further configured to set a motion command limit for a dipper motion based on the distance, the dipper motion being selected from a group of a swing motion, a crowd motion, and a hoist motion and control the dipper motion according to a dipper motion command limited by the motion command limit.

PREDICTIVE REPLACEMENT FOR HEAVY MACHINERY
Systems and methods for predicting replacement of a component of an industrial machine. One system includes an electronic processor configured to determine a wear rate of the component based on a current dimension of the component and historical dimensions of the component and determine a replacement cost for the component. Determining the replacement cost includes determining a cost of downtime for replacing the component based on a time for replacing the component and a downtime cost for the industrial machine during the time for replacing the component, a material cost in replacing the component, and an operating cost of the industrial machine associated with not replacing the component. The electronic processor is also configured to determine a replacement recommendation for the component based on the wear rate, the replacement cost, and discard criteria and output the replacement recommendation.
SYSTEM AND METHOD FOR REMOVING MATERIAL FROM A SLOPING SURFACE
A system for removing material from a sloping surface includes a plurality of cables and pulleys used to manipulate positioning of a slusher bucket across the sloping surface. A multiple drum winch communicates with the cables to selectively retract or feed the cables enabling precise positioning of the slusher bucket. An elevated upper transverse anchoring cable is used to secure one or more of the pulleys. The anchoring cable itself can be mounted to the ground by one or more ground anchors. According to another aspect of the invention, it includes an improved slusher bucket configuration with two working edges. A preferred embodiment of the bucket configuration includes a scraper edge and scarifying teeth located on another working edge.
MATERIAL TRANSFER SYSTEM FOR A BODY OF WATER
There is provided a material transfer system comprising a first reciprocating conveyor which selectively moves material towards a first location, and a second reciprocating conveyor which overlaps with the first reciprocating conveyor, with the second reciprocating conveyor selectively moving material from the first location towards a second location. There is also provided a material transfer system according to another aspect comprising a conduit in fluid communication with an upstream portion of the body of water, and a reciprocating conveyor configured to convey upstream said material in the body of water towards the conduit. There is further provided a reciprocating conveyor configured to promote movement of the material in a first direction and inhibit movement of the material in a second direction, and a conveyor position adjustment assembly configured to selectively move a first end portion of the conveyor relative to a second end portion of the conveyor.
Dipper assembly and parts thereof
A dipper assembly and parts thereof for use with a mining shovel. The dipper assembly includes: a dipper body having a back wall and an open dipper bottom; a dipper door pivotally coupled to the back wall of the dipper body and moveable between open and closed positions relative to the open dipper bottom; and a latch assembly for releasably securing the door in the closed position. The latch assembly includes a latch keeper and a latch member for engaging the latch keeper. The latch keeper is associated with the dipper body proximate the open dipper bottom and the latch member is coupled to the dipper door. The latch member includes at least one roller to assist the latch member in engaging and disengaging with the latch keeper and to reduce wear on the latch member.
Cable Drag System with Hybrid Electric Drive
A cable drag system having a drive subsystem and a tailhold on opposing sides of terrain for hauling equipment or loads. The device may include a carriage with load attachment, a mainline cable connected to a mainline winch and to the carriage to pull the carriage towards the winch. A haulback cable connected to a haulback winch and to the carriage pulls the carriage away from the winch. A drive subsystem may include: a first electric motor connected to the mainline winch; a second electric motor connected to the haulback winch; a DC bus connected to an electrical power source and an electric power storage; an electric drive controller operatively coupled to the DC bus and to the first and second electric motors, the drive controller arranged to provide power to or regenerate power from the electric motors. The result is more energy efficient than previous cable drag systems.
