  • Publication number: 20250388164
    Abstract: An apparatus for use with a road transportable chassis comprises a body and a pair of shells. The body is connected in use to the chassis and defines a floor and a ceiling disposed in stacked spaced relation, the floor being horizontal and above the chassis. Each shell comprises: a floor and a ceiling disposed in stacked spaced relation; and a wall from which the floor and ceiling protrude. The shells are moveable between: a collapsed position, wherein the shells are relatively proximal, the walls are disposed in flanking relation to the body, the ceilings of the shells overly the ceiling of the body and the floors of the shells overly the body floor; and an expanded position, wherein the shells are relatively distal, the ceilings of the shells define extensions of the ceiling of the body and the floors of the shells define extensions of the body floor.

  • Patent number: 11599108
    Abstract: A mining machine is disclosed. The mining machine may include a mobile ranging device, a movement sensor device, and a control unit. The mobile ranging device may be configured to communicate with a location sensor device and cause the location sensor device to transmit location data relating to a location of the mining machine. The movement sensor device may be configured to transmit movement data relating to a movement of the mining machine. The control unit may be configured to receive coordinate data relating to a plurality of zones and a plurality of drawpoints of a tunnel, the location data, and the movement data. The control unit may identify an active zone, determine a machine heading, determine a machine articulation, identify an active drawpoint based on the active zone, the machine heading, or the machine articulation, and cause an action to be performed in connection with the active drawpoint.
