Grove GMK5150L – ECU Optimization for a Heavy-Duty All-Terrain Crane
The machine in the photo is a Grove GMK5150L, a five-axle all-terrain crane built for demanding lifting work and long-distance transfers between job sites. Cranes in the 150-ton class rely heavily on the performance of their carrier engine — not just for mobility, but also for maintaining consistent control while moving with ballast, trailers, or additional equipment. The GMK5150L combines a robust highway-capable chassis with a powerful Mercedes-Benz diesel engine, designed to move this massive machine safely and efficiently.
During our visit, AgroEcoPower carried out a software-based ECU optimization on the carrier engine. This upgrade focuses on improving real-world drivability: stronger pull at lower RPM, better throttle response during take-off, and smoother behavior during gear changes. The calibration is performed entirely through software, with no mechanical modifications required.
What the optimization improved
- Higher usable power across the working RPM range
- More confident acceleration when moving with ballast or towing support trailers
- Smoother throttle response, especially at low speeds and on inclines
- Reduced fuel consumption during transfers between sites
- Stable engine behavior even during heavier load transitions
With the new calibration, the GMK5150L handles on-road travel more easily and keeps its momentum better when climbing or maneuvering. For crane operators and fleet owners, these improvements translate into lower operating costs, more predictable performance, and reduced strain on the drivetrain during everyday operation.
AgroEcoPower continues to support not only agricultural machinery, but also cranes, trucks, excavators, and other heavy-duty equipment used across the United States. Proper engine optimization ensures that machines like the Grove GMK5150L remain efficient, responsive, and ready for the next job.
