A system for an excavating machine includes a control system comprising a processing system, one or more sensors, a user interface, and a vision system, wherein the control system receives input signals from the user interface, the one or more sensors, and the vision system; and a motor in communication with the control system and the motor adapted to control movement of a portion of the excavating machine. The processing system can control operation of the motor.

A dragline bucket assembly including: a cutting edge including a lip and a plurality of teeth or tooth assemblies attachable to the lip and a floor extending rearward from the cutting edge and having side walls extending upward from the periphery of the floor to extend about the floor from one end of the cutting edge to the other, the lip being attachable to the side walls by bolting or by bolting and welding.

A mining shovel includes a base, a revolving frame coupled to the base and rotatable about an axis, a boom pivotally coupled to the revolving frame, a handle coupled to the boom, and a dipper coupled to the handle. The dipper has a dipper door, and is located at a front end of the shovel. A counterweight having a center of gravity is disposed at the rear end of the shovel to balance the shovel, and is supported by a truss structure that is coupled to the revolving frame, such that the center of gravity is disposed above the revolving frame.

A dragline bucket can comprise: a bottom wall; a first sidewall portion extending from the bottom wall and defining a first upper edge portion; a second sidewall portion extending from the bottom wall and defining a second upper edge portion; a lip assembly at a front side of the bottom wall; an arm having a base portion, a first extension extending from the base portion to the first sidewall portion, and a second extension extending from the base portion to the second sidewall portion, the first and second extensions each having a connection interface, and the base portion having an upper surface that is planar; and a dump anchor fixedly coupled to the upper surface of the base portion of the arm.

A bearing assembly for a driveshaft that facilitates a swinging movement of a frame of a dragline with respect to a base of the dragline. The bearing assembly includes a housing, a spherical bearing, and a thrust bearing. The housing is fixedly engageable with the frame and defines a cavity to provide rotatable passage to the driveshaft therethrough. The spherical bearing is engageable with each of the housing and the driveshaft for journaling the driveshaft in the cavity and facilitating a rotation of the driveshaft about a longitudinal axis and an angulation of the driveshaft with respect to a reference axis. The thrust bearing is configured to be supported against each of the driveshaft and the housing to accommodate the angulation of the driveshaft and an axial load passing along the longitudinal axis away from the spherical bearing onto either of the housing or the frame.

A dragline bucket can comprise a bottom wall; a first sidewall defining a first upper edge; a second sidewall opposite the first sidewall defining a second upper edge; a first forward-facing projection on a first side of the dragline bucket; a second forward-facing projection on a second side of the dragline bucket opposite the first side; a lip assembly at a front of the bottom wall; and an arm extending from the first side to the second side of the dragline bucket, a distal end of the arm being at a height greater than a height of respective first and second upper edges of the first and second sidewalls. In a side elevational view of the dragline bucket, the arm is tilted away from the rear wall at an angle relative to vertical.
