R-150

R-150 roadheader is designed to excavate galleries in section up to 24 m2 in rocks having a compressive strength up to 95 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-150 has a CE mark.

The R-150 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
  • ergonomic display control system and high maneuverability
  • two types of haulage systems: electric with constant speed of 5m/min or hydraulic with adjustable speed from 0 to 5 m/min
  • easy operation and maintenance
  • easy underground transportation of each component
  • easy underground assembly
  • surfaces exposed to wear are covered with materials of great resistance to abrasion
  • the hydraulic system is adapted to feed external hydraulic receivers with a pressure from 12 to 20 MPa
  • load-dependent hydraulic system – LOAD-SENSING ensuring: lower electric power consumption, lower hydraulic oil temperature, higher durability of hydraulic system subassemblies
