Additional Notes

  • The Kalmar DRF 420 and DRF 450 reach stackers fitted with the Cummins QSM11 engine share a cooling system capacity of 40 liters, applying to normal use conditions from 2003.
  • Both the DRF 420 and DRF 450 configured with the Volvo TAD1250VE engine also carry a 40-liter cooling system capacity under normal use, with specifications beginning from 2005.
  • The Volvo TWD1240VE engine configuration, available in both the DRF 420 and DRF 450 from 2003, requires a significantly larger cooling system fill of 68 liters under normal use conditions.
  • The 68-liter capacity associated with the TWD1240VE represents a 70 percent increase over the 40-liter figure seen in the QSM11 and TAD1250VE configurations, reflecting the greater thermal management demands of a larger displacement engine.
  • Across all six configurations, the capacity values listed represent cooling system fills under normal use, which in service documentation typically refers to standard operating environments as opposed to severe or high-cycle duty conditions.
  • The Cummins QSM11 and Volvo TAD1250VE engines produce identical 40-liter cooling system capacities across both the DRF 420 and DRF 450 models, indicating no variation in cooling system volume between those two reach stacker variants when paired with either of those engines.
