摘要： A cutting assembly is provided for a rock excavation machine having a frame. The cutting assembly includes a base portion configured to be supported by the frame, a flexible shaft, and a cutting device. The base portion defines a base axis. The flexible shaft includes a first end and a second end opposite the first end. The first end is coupled to the base portion, and the second end is movable relative to the first end and deflectable away from the base axis. The cutting device is supported on the second end of the flexible shaft.

摘要： An energy storage system is selectively mountable to a vehicle and includes a frame, a battery supported on the frame, and a frame mounting interface. The frame includes a base surface and a mounting surface. At least a portion of the base surface is positioned in a plane oriented at an acute angle relative to a direction that is perpendicular to the mounting surface. The base surface may rest on a ground surface while the frame is not mounted to the vehicle. The frame mounting interface is positioned adjacent the frame mounting surface. The frame mounting interface may engage a chassis mounting interface positioned on a chassis of the vehicle, and the engagement of the base surface with the ground surface causes the frame mounting interface to be positioned in an orientation that may facilitate engagement with the chassis mounting interface while the frame is not mounted on the vehicle.

摘要： A cutting assembly for a rock excavation machine having a frame includes a boom and a cutting device supported on the boom. The boom includes a first portion and a second portion, the first portion supported for pivotable movement relative to the frame. In some embodiments, the first portion includes a first structure extending along a longitudinal base axis and a second structure moveable relative to the first portion in a direction parallel to the longitudinal base axis, and at least one bearing supports the second portion for movement relative to the first portion. In some embodiments, the second portion is pivotably coupled to the first portion by a universal joint, and a suspension system including a plurality of biasing members may be coupled between the first portion and the second portion.

摘要： A system and method for offboard monitoring are provided. The system may include a remote monitoring vehicle including one or more sensors, a drive mechanism for driving the remote monitoring vehicle; and a controller coupled to the one or more sensors and the drive mechanism. The controller may be configured to navigate the monitoring vehicle along a predetermined path of the industrial site; receive sensor data relating to an equipment; determine a state of the equipment based on the sensor data; determine whether the state of the equipment meets a threshold state for maintenance; and generate an alert indicating a maintenance event for the equipment when the state of the equipment meets the threshold state for maintenance.

摘要： A rock excavating device includes a shaft and a cutting element. The shaft includes a first portion and a second portion connected to an end of the first portion. The first portion is rotatable about a first axis. The second portion extends along a second axis that is oblique with respect to the first axis. The cutting element includes a cutting edge. The cutting element is supported on the second portion and rotatable about the second axis. Rotation of the first portion of the shaft about the first axis changes the orientation of the second axis and the cutting element.

摘要： A method for removing material from a rock wall. The method includes moving a cutting edge through the rock wall to create a first slot in the rock wall, moving the cutting edge through the rock wall to create a second slot in the rock wall, the second slot being separated from the first slot by an uncut portion, the uncut portion defining a base surface attached to the wall, cutting a notch into the base surface of the uncut portion, and applying a force on the uncut portion to break the uncut portion away from the wall.

摘要： A roof support includes a base, a canopy for engaging a mine surface, a shield coupled to the canopy, and a link coupled between the base and the shield. The canopy is supported relative to the base and includes an end configured to be spaced apart from a mine face by a distance. The link is movable between a first position and a second position, and movement of the link between the first position and the second position causing the distance to change.
