Grove Cranes Mobile cranes

Additional Notes

• The Grove Cranes Mobile cranes AdBlue (DEF) tank capacities across the three listed configurations range from 37.8 liters to 40 liters, reflecting the scale of heavy-duty crane carrier engines and their SCR system demands.
• The GMK3060 with a Cummins QSL9-C engine carries an AdBlue (DEF) tank capacity of 37.8 liters. The QSL9-C is a 9-liter inline-six diesel, and a 37.8-liter DEF tank is proportionate to the extended operational cycles typical of mobile crane work.
• The GMK4080-2 and GMK4090, both fitted with the Mercedes-Benz OM470LA engine, share an identical AdBlue (DEF) tank capacity of 40 liters. The OM470LA is a 10.7-liter inline-six diesel, and the shared capacity reflects the same engine platform used across two distinct crane models.
• All three configurations list normal use conditions, meaning the 37.8-liter and 40-liter capacities apply to standard operating environments rather than severe-duty or first-fill scenarios.
• The selective catalytic reduction (SCR) system noted across all three rows is an exhaust aftertreatment technology that injects DEF into the exhaust stream to reduce nitrogen oxide (NOx) emissions, which explains why a dedicated fluid reservoir with a defined capacity is specified separately from engine oil or coolant.
• The 2.2-liter difference between the Cummins QSL9-C tank at 37.8 liters and the Mercedes-Benz OM470LA tank at 40 liters indicates that engine displacement and manufacturer SCR system design both influence DEF reservoir sizing, even within the same crane product family.
