Zoomlion Rough terrain cranes, RT

Automatic transmission fluid capacity & service interval

Zoomlion Rough terrain cranes, RT utilize automatic transmission fluid with a capacity range of 45 to 50 liters. Service intervals include checks at 1 month and changes at 250 hours or 1000 hours/6 months. The data covers 10 configurations.

Additional Notes

  • The Zoomlion RT35 rough terrain crane carries a powershift transmission fluid capacity of 45 liters, which is the smallest capacity across all listed RT configurations and reflects the smaller scale of the QSB6.7-powered RT35 relative to the larger models in the range.
  • The RT55, RT60, RT75, and RT100 all share a 50-liter powershift transmission fluid capacity, despite the RT55, RT60, and RT75 using the Cummins QSB6.7 and the RT100 using the larger Cummins QSC8.3. Equal transmission capacity across different engine displacements indicates the powershift unit itself, rather than the engine, determines fluid volume.
  • All listed configurations carry an initial service fluid change interval of 250 hours. In powershift transmissions, this early change interval is standard practice to flush out metal particles and manufacturing residues that accumulate during the break-in period of new clutch packs and gear sets.
  • Under normal use conditions, the fluid change interval for all listed models is 1,000 hours or 6 months, whichever comes first. The dual-trigger format means that machines with lower annual utilization are still subject to a time-based change, preventing fluid degradation from extended static periods.
  • A monthly fluid level check interval applies to all listed configurations under normal use conditions. Monthly checks on a powershift transmission are consistent with the high hydraulic pressures and heat cycles involved in crane operation, where fluid loss or contamination can develop gradually between scheduled changes.
  • The initial service change at 250 hours represents one quarter of the standard 1,000-hour normal-use interval. No check interval is specified for the initial service period, meaning the monthly check schedule applies only once the transmission transitions to the normal service cycle.
