A mining machine includes a frame, a boom coupled to the frame, a handle coupled to the frame and a dipper coupled to the handle. The handle includes an extension, and a bail is coupled directly to the extension, such that the bail is isolated from the dipper.

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.

A shovel includes a lower travelling body; an upper turning body pivotably mounted on the lower traveling body; a camera that is attached to the upper turning body and that is capable of stereo photographing; and a measurement device including a processor; and a memory that includes instructions, which when executed, cause the processor to execute the following step: measuring a landform in a vicinity of the shovel based on stereo-pair images captured by the camera during turning or traveling of the shovel.

A common connection apparatus for coupling a power tool to an extensible arm and a power supply, the apparatus including a tool support base designed to support a tool, and a power supply support base designed to be affixed to the end of the extensible arm. The tool support base and the power supply support base each include a plurality of power connectors, positioned for engagement when the bases are aligned. The tool support base also has an alignment stab, which is received within a channel of the power supply support base. A plurality of pins are further positioned on the tool support base, to be received in apertures of the power supply support base. By this configuration, the bases may be aligned and engaged, facilitating the transmission of power from the machinery to which the arm is affixed, to the tool.

A mining machine assembly includes a dipper having a main body, the main body having a front side, a back side, a bottom side, and a top side. A ground engagement portion extends from the front side, the ground engagement portion including digging teeth. The mining machine assembly also includes a hoist rope attachment assembly coupled to the dipper. The hoist rope attachment assembly is configured to directly couple a hoist rope to the dipper. The hoist rope attachment assembly includes a cam having a first portion extending from the top side of the main body of the dipper, and a second portion that extends from the first portion and away from the main body and digging teeth.

A mobile apparatus includes a main frame, an operating arm connected to the main frame, drive means configured to drive displacing means of the mobile apparatus, such as one or more wheels or tracks, drive means configured to drive the operating arm and a control system, connected to operating instruments for a driver, for controlling the drive means. The drive means for the displacing means includes an electric motor such that the drive of the displacing means is substantially electrical.

A system and method for capturing information related to mining machine performance and making the information accessible to remote maintenance staff. The information can be used to generate alarms, determine a state of the machine, determine performance statistics for the machine, and identify problems with the machine that may require attention. The information can be provided in a state message and the data can be packaged as XML data or in a string format. The data associated with a message can be particular to the current state or context of the mining machine. That is, in the case of a rope shovel, different data may be included in a message generated in a swing state versus a message generated in a tuck state. In some instances, a message is generated when progress thresholds are satisfied, such as for each foot of drilling performed by a mining drill.

Systems and methods for compensating dipper swing control. One method includes, with at least one processor, determining a direction of compensation opposite a current swing direction of the dipper and applying the maximum available swing torque in the direction of compensation when an acceleration of the dipper is greater than a predetermined acceleration value. The method can also include determining a current state of the shovel and performing the above steps when the current state of the shovel is a swing-to-truck state or a return-to-tuck state. When the current state of the shovel is a dig-state, the method can include limiting the maximum available swing torque and allowing, with the at least one processor, swing torque to ramp up to the maximum available swing torque over a predetermined period of time when dipper is retracted to a predetermined crowd position.
