Body of the machine With a tank-like frame and rotating frame

  • High strength steel fabrications;
  • Inside chambers are used as a tank, this provides compact confguration of the body.

Cutting boom

  • High strength steel gears;
  • "DAMEL" 132 KW power electric motor with a water cooling system.

Crawler undercarriage

  • A tractive force of 28 t is ensured by means of application of high -torque waveform gear reduction units with intermediate rollers;
  • 740 mm wide tracks maintain a specifc ground pressure of 7,1 íPÁ..

Gathering apron

  • 4000 mm wide with detachable gatherer boards and individual hydraulic drives;
  • "double cone" pin seals.

Magnetic station

  • "Il'ma" production with easy- to- remove covers.;
  • diagnosis of the road header operation;
  • radio controlled from a remote control panel.

Pump station

  • 110 KW power pump station;
  • gear pumps and hydraulic control components are imported.
