HW300 Optional Equipment

  • Used to guide the cutter module through the coal seam, leaving predetermined amounts of coal in the roof and floor. This system also allows the mining of coal in soft roof and/or soft floor situations.

  • For hot-climate applications, this package extends the operating temperature of the equipment up to 55° C (131° F).

  • For extreme-cold climates, this package extends the operating temperature to -40° C (-40° F).

  • This feature discharges coal to the right or left of the machine.

  • This tool is mounted to the front of a wheel loader to provide safe and efficient transportation of push beams to and from the highwall mining system.

  • A self-contained generator system provides electrical power to the highwall mining system in remote locations where connection to a utility grid is not practical.
