Hydraulic vibrators

Main features of the MR-vibrator series:

  • Resonance-free start up and shutdown of vibrator
     
  • Special cylindrical roller bearing 
    • High economic high life-time of bearings 
    • Force-feed lubrication of bearings
       
  • Dry sump lubrication
    • Lubrication with hydraulic oil of base carrier (also with
      biodegradable oil) 
    • high efficiency of gearbox without splash losses
    • Separate oil changes can be omitted 
    • Low operating temperature in gearbox
       
  • Recording and control of safety-relevant operating data of
    the vibrator 
    • Clamping pressure 
    • Leak oil pressure
    • Lubrication oil pressure and temperature
