Additional Notes

  • The Kalmar Reach Stacker DRF 420 and DRF 450 both share an identical hydraulic tank capacity of 140 liters across all listed engine variants, indicating a common hydraulic system architecture between the two model designations.
  • Wet brake systems, as specified across all six configurations, are hydraulically actuated and immersed in oil rather than exposed to air. The hydraulic tank serves as the fluid reservoir for both the brake circuit and other hydraulic functions, which explains the relatively large 140-liter capacity figure.
  • A 140-liter hydraulic tank capacity is characteristic of a full-system service fill rather than a component-level or partial fill. In heavy equipment of this class, such volumes account for fluid distributed across cylinders, hoses, actuators, and the tank itself.
  • The Volvo TAD1250VE engine variant appears in both the DRF 420 and DRF 450 with a starting year of 2005, while the Cummins QSM11 and Volvo TWD1240VE variants in both models carry a starting year of 2003, reflecting a later introduction of the TAD1250VE engine option.
  • All six configurations carry a normal use condition designation, meaning the 140-liter hydraulic tank capacity applies under standard operating conditions rather than severe-duty cycles.
  • Despite differences in engine manufacturer and displacement between the Cummins QSM11, Volvo TAD1250VE, and Volvo TWD1240VE, the brake system hydraulic tank capacity remains uniform at 140 liters, suggesting the brake and hydraulic system design is independent of engine selection on these models.
