The Zoomlion ZE550G is a 53.5-tonne large crawler excavator built around a 6-cylinder, 11.8-litre Cummins engine with high-pressure common rail technology. A new electronic control system optimises engine performance for better whole-machine fuel economy, while maximum engine output reaches 340 kW at 1,800 rpm for stronger, smoother power when the work demands it. A large-displacement main pump, large-diameter main valve and large-displacement dual swing motors back that up, making this a genuine bulk-production machine for quarrying and major earthmoving.
