    摘要： Methods and systems for evaluating underground road conditions using accelerometers. One system includes an electronic processor that receives sensor data from an accelerometer and location data of a mining machine operating within a mining environment. The electronic processor determines, based on the sensor data, a first data point when acceleration in a first direction exceeds a predetermined first threshold based on the sensor data, and determines a second data point when acceleration in a second direction opposite the first direction exceeds a predetermined second threshold. The electronic processor also determines a location of a road condition associated with the first data point and the second data point based on the location data and takes at least one automatic action to correct the road condition.

    摘要： A tensioning mechanism for a conveyor system includes a first end including a drive unit, an anchor structure, a continuous belt extending at least partially between the drive unit and the anchor structure, a first carriage, and a second carriage. The first carriage is coupled to the drive unit and supports a portion of the belt. The first carriage is supported for movement relative to the drive unit to adjust a tension in the belt, and the first carriage is movable between the drive unit and an intermediate position. The second carriage is releasably secured to the anchor structure and supports another portion of the belt. The second carriage is supported for movement relative to the anchor structure between a first position and a second position. A distance between the first end and the second carriage defining a take-up length, and movement of the second carriage changes the take-up length.

    摘要： A breaker pick retainer system for a breaker includes a holder that defines a pick aperture and a pin aperture, and a breaker pick received in the pick aperture of the holder and including a pin receiving feature aligned with the pin aperture. The breaker pick retainer system including a pin received within the pin aperture of the holder and seated in the pin receiving feature of the breaker pick for maintaining the breaker pick within the holder. The breaker pick retainer system further including a resilient plug received within the pin aperture for sealing the pin aperture. The plug inhibits removal of the pin from the pin aperture.

    摘要： A mining machine includes a boom, a cutter head, a valve, and an actuator. The boom defines an internal chamber and includes a first end coupled to a frame, a second end, and an opening in fluid communication with the internal chamber. The cutter head includes a plurality of cutting bits and is supported on the second end of the boom. The valve is coupled to the boom and is movable between a closed position in which the opening is covered and an open position in which the opening is at least partially uncovered. The actuator is coupled to the valve to selectively move the valve between the closed position and the opened position.

    摘要： A method of manufacturing a multi-piece shaft for an idler roller. The method includes providing a tube having a first end and a second end, mechanically crimping the first end of the tube to a first stub to secure the first stub to the first end of the tube with a mechanical interlock, and mechanically crimping the second end of the tube to a second stub to secure the second stub to the second end of the tube with a mechanical interlock. The first stub extends from the first end of the tube and the second stub extends from the second end of the tube.
