R-2000 roadheader is a machine designed to excavate galleries in section up to 43.1 m2, in rocks having a compressive strength up to 110 MPa.

The machine can operate in underground excavations without methane inflow, or in excavations with the methane hazard classified as “a”, “b” or “c” degree of methane explosion hazard or to “A” or “B” class of coal dust explosion, provided that the power supply is disconnected when the maximum methane concentration exceeds 2%. The R-2000 has a CE mark.

The R-2000 roadheader complies with the requirements of the following EU directives:

  • 2006/42/EC – Machinery Directive
  • 94/9/EC – Directive on equipment and protective systems intended for use in potentially

    explosive atmospheres (ATEX)

  • 2004/108/EC – EMC Directive
  • high productivity and reliability during exploitation
  • load-dependent automatic boom movement speed control
  • excavation guidance system and a programmable cutting boom guidance system
  • machine states and extraction processes monitoring and registering system
  • easy operation and maintenance
  • easy underground transportation of each component
  • surfaces exposed to wear are covered with materials of great resistance to abrasion
  • load-dependent hydraulic system LOAD-SENSING ensuring: lower electrical power consumption, lower hydraulic oil temperature, higher durability of hydraulic system subassemblies
  • hydraulic system is adapted to feed external hydraulic receivers with a pressure from 12 to 20 MPa
  • automatic central lubrication system
