Designed for demanding jobsite conditions, EC-Oil improves productivity while minimising wear, contamination risk, and operator exposure.



EC-Oil provides clear operational advantages, including:


  • Automatic hydraulic, electrical, and lubrication connection
  • Tool changes in approximately 10 seconds
  • No manual hose handling
  • Improved operator safety
  • Reduced downtime and increased utilisation

Available Options

The EC-Oil system is available in multiple sizes to suit different excavator classes and attachment requirements:
