Dipper Handle

A dipper handle includes a dipper tube, a dipper engagement member, and an intermediate member between the dipper tube and the dipper engagement member. The dipper tube has a substantially cylindrical outer surface and a contoured inner surface. The contoured inner surface results in multiple wall thicknesses for the dipper tube, including a first thickness proximate a first end and a second, larger thickness, proximate a second end. The second end is configured for coupling to the intermediate member.

MODULAR GROUND ENGAGEMENT TOOLING SYSTEM
20230193598 · 2023-06-22 ·

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.

DIPPER HANDLE ASSEMBLY YOKE HAVING A TRANSITION PORTION DISTAL END WITH ANGLED ORIENTATION

A dipper handle assembly includes a tube coupled to a yoke. The yoke has a collar extending along a collar axis, a transition portion, a first arm and a second arm. The transition portion includes a distal end having first and second lateral sections and first and second transverse sections. The first and second lateral sections and the first and second transverse sections all lie in a virtual transition portion distal end plane, and the virtual transition portion distal end plane intersects the collar axis at an oblique angle.

DIPPER HANDLE ASSEMBLY

A yoke of a dipper handle comprises a collar and a crowd pin aperture extending along a crowd pin aperture axis. First and second arms of the yoke include dipper pin lug apertures aligned along a dipper pin aperture axis parallel to the crowd pin aperture axis. The first and second arms of the yoke further include first and second pitch brace lug apertures aligned along a pitch brace aperture axis parallel to the crowd pin aperture axis. A first virtual reference line extends between the crowd pin aperture axis and the dipper pin aperture axis, while a second virtual reference line extends between the crowd pin aperture axis and the pitch brace aperture axis. An included angle α between the first virtual reference line and the second virtual reference line is between approximately 25 to approximately 51 degrees.

AUTOMATIC TILT CONTROL
20170298592 · 2017-10-19 ·

An industrial machine and methods for providing automatic tilt control for the same. One method includes determining a current tooth vector of a tooth included on a bucket of the industrial machine and a current path vector of the tooth and determining a current digging angle between the current tooth vector and the current path vector. The method also includes determining a delta angle based on the current digging angle and a target angle and automatically adjusting a tilt of the bucket based on the delta angle.

Drive mechanism for mining attachment

A rope shovel has a boom and a hoist rope. The boom has a first end and a second end. The hoist rope extends over the second end of the boom. A digging assembly for the rope shovel includes a shaft, an elongated member supported for movement relative to the boom, an attachment, and a drive link. The shaft is positioned between the first end and the second end of the boom and transverse to the boom, and the shaft includes at least one pinion gear. The elongated member includes a first end and a second end. The attachment is coupled to the first end of the elongated member and is configured to be coupled to the hoist rope. The drive link includes a rack engaging the pinion gear of the transverse shaft such that rotation of the pinion gear moves the drive link and actuates the attachment.

DIPPER HANDLE CROSS MEMBER
20170233979 · 2017-08-17 ·

A handle configured to attach an implement to an industrial machine. The handle includes a first member, a second member, and a third member extending between the first member and the second member. The third member includes a first transition extending toward the first member and a second transition extending toward the second member.

SYSTEM AND METHOD FOR ESTIMATING A PAYLOAD OF AN INDUSTRIAL MACHINE
20220307219 · 2022-09-29 ·

A method of determining a payload mass, the method comprising receiving rope data indicative of the rope force from the rope force sensor, receive position data indicative of the current shovel position from the one or more position sensors, determine a payload mass based on the rope force, the current shovel position, and a defined relationship between a kinetic energy of the mining shovel, a potential energy of the mining shovel, one or more degrees of freedom of the mining shovel, and one or more forces experienced by the mining shovel, and provide the payload mass to a display device associated with the mining shovel.

Controlling crowd runaway of an industrial machine

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.

Modular ground engagement tooling system

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.
