Swivel system

  • Horizontal swiveling via large hydraulic cylinder with very large swiveling range of 145 cm
  • Ball bearing mounted turntable in heavy-duty design for implementation of the horizontal swivel movement
  • Vertical swiveling via large hydraulic cylinder with optimum geometrical steering for continuous grinding
  • Stable, widely spaced bearing points to absorb vertical and horizontal forces
  • Grinding height above ground level 50 cm
  • Grinding depth below ground level 50 cm
  • Extremely stable grinding due to low center of gravity of the machine and balanced weight distribution of engine and fluids in the tanks
  • The vertical swivel movement of the grinding arm is decoupled from the engine

Grinding arm

  • Robust grinding arm construction
  • Widely spaced bearing points with over-dimensioned bearings provide a durable, very rigid construction
  • Control via large hydraulic cylinder with optimum geometric steering position and results in high rigidity during grinding. Possible vibrations and sudden grinding wheel movements are avoided
  • Small grinding width based on the v-belt drive with hydraulic motor on top allows optimum view on the grinding area
  • Large pulleys for a powerful and durable drive
  • Grinding wheel drive via hydraulic motor, which can be electro-hydraulically activated
