Cummins has taken a major leap forward with engine design as it ditches cooled exhaust gas recirculation for its newest heavy-duty six-cylinder engine platform launched at bauma – the 12-litre QSM12. As its Tier 4 Final/Stage 4 engine solution in the 250-383kW sector, the QSM12 benefits from higher efficiency air handling and an advanced in-cylinder combustion process, allowing a return to using a straightforward wastegated turbocharger.

Models brought to bauma by Soilmec included two new multipurpose hydraulic crawler cranes for heavy-duty applications. Among key features of the SC-70 and SC-90 is a design that enables easy transport and set-up on site. The cranes are modular for fast conversion between a range of applications, such as use with a hydraulic or mechanical grab, hydromill, chisel, vibratory driver or clamshell. New Tier 4 engines are available.
