Additional Notes

  • The Hitachi EH1100-3 rigid dump truck, introduced from 2008, carries a cooling system capacity of 224.5 liters, the smallest figure among the EH series entries listed here, reflecting the comparatively smaller engine and cooling circuit of this model tier.
  • The EH1700-3 cooling system capacity of 497 liters represents a substantial increase over the EH1100-3, consistent with the larger powertrain and greater thermal load management requirements of a heavier-class rigid dump truck.
  • The Hitachi EH4500-2 is listed in two distinct engine configurations — one with a Cummins engine and one with a Detroit Diesel engine — both covering the 2008-2013 model years and both sharing an identical cooling system capacity of 697 liters, indicating that the cooling circuit volume was standardized across engine variants at this truck class.
  • The EH5000 equipped with a Detroit Diesel engine, spanning 2000-2009, also carries a 697-liter cooling system capacity, placing it in the same volumetric range as the EH4500-2 despite belonging to a different model designation and an earlier production window.
  • All five configurations across the EH series are rated under normal use conditions, meaning the 697-liter, 497-liter, and 224.5-liter capacities each apply to standard operating environments rather than severe-duty or first-fill scenarios.
  • A cooling system capacity in the range of several hundred liters, as seen across the larger EH models, is characteristic of heavy mining equipment where engine heat rejection demands require proportionally large coolant volumes to maintain stable operating temperatures across extended duty cycles.
