A mining machine includes a frame, a boom, an elongated member supported by a pivot element for movement relative to the boom, and a digging attachment. The boom includes a first end coupled to the frame and a second end opposite the first end. The pivot element is positioned between the first end and the second end of the boom. The hoist rope includes a portion extending over the second end of the boom. The member includes a first end, a second end, a first portion proximate the first end of the member, and a second portion positioned between the first portion and the second end of the member. At least a portion of the second portion is oriented at an angle relative to the first portion. The digging attachment is coupled to the second end of the member and is supported by the hoist rope.

A bucket height notification device includes a bucket height specification unit and a bucket height notification unit. The bucket height specification unit specifies a bucket height from a ground surface to a bucket of work equipment included in a work vehicle related to remote operation. The bucket height notification unit notifies of the bucket height.

An equalizer for a mining machine includes an equalizer main body, an internal chamber defined by the main body configured to retain lubrication, and a bushing disposed within the internal chamber. The bushing includes an opening. The equalizer further includes a pin disposed partially in the internal chamber and extending through the opening.

A mining shovel with compositional sensors comprises a bucket having various inward looking sensors positioned throughout the bucket. The bucket can also have disposed thereon a control enclosure that houses processing equipment that receives and analyzes the data collected by the inward looking sensors. The mining shovel with compositional sensors can be used as part of a system to manage a mining field, including generating and transmitting instructions directing where to deposit material located in the bucket based on the data collected from the inward looking sensors positioned in the bucket.

A hoist rope connector for a rope shovel includes a link extending between a first end and a second end. A rope attachment member is positioned adjacent the first end and configured to engage a hoist rope. A spherical coupling is positioned adjacent the second end and configured to be coupled to a dipper. The spherical coupling permits rotational movement between the second end and the dipper in multiple directions.

A dimension-specifying device specifies dimensions of an attachment of work equipment including an arm and the attachment. In the work equipment a first connection portion or a second connection portion provided at the attachment is connected to the arm. The dimension-specifying device includes a dimension storage unit and a dimension calculation unit. The dimension storage unit stores first dimensions of an attachment when a first connection portion is connected to an arm. The dimension calculation unit calculates second dimensions of the attachment when a second connection portion is connected to the arm on the basis of the first dimensions.

A center pintle hub to be affixed to a base of a machine. The center pintle hub includes a base portion and a support portion. The base portion is formed to be affixed to the base. The support portion extends from the base portion and has a frusto-conical shape that can receive a center pintle shaft. The center pintle shaft can support a frame of the machine and provide rotation of the frame with respect to the base.

An arrangement for a construction machine includes a machine frame; and an articulated boom. The articulated boom is arranged on the machine frame. The articulated boom includes a proximal arm that is mounted in an articulated manner to the machine frame and a distal arm that is connected in an articulated manner to the proximal arm. The arrangement is configured to be operated in an operational mode, in which the proximal arm and the machine frame are interlocked.

A construction machine comprises a machine frame and an articulated boom pivotably mounted to the machine frame. An electric motor is connected to a battery for operating a component of the construction machine. The construction machine is configured to be operated in a loader mode in which a first tool is mounted to the articulated boom, and in an excavator mode in which a second tool is mounted to the articulated boom. The construction machine comprises a tool storage for storing the first tool and/or the second tool. The construction machine is configured to replace one of the first tool and second tool when mounted to the articulated boom with the other one of the first tool and the second tool when stored in the tool storage. A method of changing an operational mode and a method of selecting an operational mode of a construction machine are also described.

An excavator attachment is attached to an excavator rotating platform. During normal operation, a drive means drives the attachment according to operator input into a manipulation device. A sensor detects motion of the excavator. Based on output of the sensor, a slip suppression unit detects slipping of the excavator undercarriage in an extension direction of the attachment, and corrects operation of the attachment performed by the drive means.
