A digging attachment for an industrial excavating machine includes a first housing portion including a first housing opening, a second housing portion including a second housing opening, and an intermediate portion positioned between the first housing portion and the second housing portion. The intermediate portion may be one of a plurality of intermediate portions each having a different length that corresponds to a different volume of a cavity of the digging attachment. The length of the intermediate portion can determine the volume of the cavity. The intermediate portion may have open ends that complement a profile of the first and second housing openings. The cavity may have a substantially continuous profile between the first housing opening, the open ends of the intermediate portion, and the second housing opening. The intermediate portion may be omitted and the first housing portion may be directly couplable to the second housing portion.

A mining machine includes a boom, a handle coupled to the boom, a dipper coupled to the handle, and a dipper door pivotally coupled to the dipper. The mining shovel also includes a dipper door trip assembly including a trip motor coupled to the boom, a trip drum coupled to the handle, a linkage assembly coupled to the dipper door, a first actuation element extending directly from the trip motor to the trip drum, and a second actuation element extending directly from the trip drum to the linkage assembly.

A tooling system includes a dipper having a lip with a plurality of apertures, the apertures extending at least partially through the lip. The tooling system also includes a modular adapter configured to be inserted partially into one of the apertures along an axis of insertion. The adapter is configured to be releasably coupled to the lip. The adapter includes a first portion configured to extend into the aperture, and a second portion configured to extend out of the aperture. The tooling system also includes a locking system including a fastener configured to extend at least partially into the aperture and couple to the adapter to the lip.

Tooling systems for a digging attachment include one or more tooth assemblies including a moveable tooth. A working length of the tooth may be adjusted and/or replenished by movement of the tooth in response to wear or damage on the tooth. The tooth assembly includes the tooth and a shroud that is positioned adjacent a lip of the digging attachment. The tooth is moveable within a cavity of the lip relative to the shroud, and through an opening defined in the shroud.

A vibration monitoring system for a mining machine, the mining machine including a plurality of movable components and one or more motor operatively coupled to the plurality of movable components. The system including a plurality of sensors, each of the plurality of sensors positioned at one of a plurality of measurement points on at least one of the movable component of the industrial machine, and an electronic processor coupled to the plurality of sensors and configured to receive a signal including a parameter related to a motion of the at least one moveable component, identify a steady state of the industrial machine based, at least in part, on the parameter meeting a predetermined criteria, receive, from the plurality of sensors, a plurality of vibration data sets, and select a vibration data subset from the plurality of vibration data sets corresponding to the steady state of the industrial machine.

A mining machine includes a boom, a handle coupled to the boom, a dipper coupled to the handle, and a dipper door pivotally coupled to the dipper. The mining shovel also includes a dipper door trip assembly including a trip motor coupled to the boom, a trip drum coupled to the handle, a linkage assembly coupled to the dipper door, a first actuation element extending directly from the trip motor to the trip drum, and a second actuation element extending directly from the trip drum to the linkage assembly.

The adapter includes a first portion configured to extend into the aperture, and a second portion configured to extend out of the aperture. The tooling system also includes a locking system including a fastener configured to extend at least partially into the aperture and couple to the adapter to the lip.

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.

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.
