  • Road rollers (single and double drum)
  • Asphalt pavers
  • Wheel loaders
  • Skid steer loaders
  • Compact track loaders
  • Excavators (travel drive systems)

Advantages:

  • High starting torque for heavy load conditions
  • Smooth hydrostatic travel control
  • Stable performance under variable load

1.2 Road Construction Equipment

These motors are particularly suitable for continuous-duty road machinery:

  • Soil compactors
