Hydrema and Cummins team up for early 90kW Stage V release


High-tech earth-moving and mine-clearing vehicle manufacturer Hydrema has become one of the first equipment providers to receive series production of Cummins’ F3.8 Performance Series engine, four months ahead of Stage V emissions requirements for the 90 kW power rating.

Cummins’ F3.8 Performance Series engine will power Hydrema’s new 707G dump truck which is available in two sizes, 90 kW (122 hp) and 55 kW (74 hp). Although Stage V requirements for the 90 kW model do not come into force until January 2020, Cummins brought forward its Stage V certification to enable Hydrema to launch both models at Bauma 2019.

“We are excited to be working with Hydrema to set new standards for machine performance, lower emissions and improved on-site safety,” says Raj Chauhan, Customer Engineering Director, Cummins Europe. “The F3.8’s peak torque increases by more than 20% at Stage V, resulting in more power at lower revs, improved fuel economy, reduced noise levels and most importantly, reduced impact on the environment.”

Part of Cummins’ Performance Series, the 90 kW F3.8 delivers more power and increased machine capability with simpler architecture and lower weight resulting from an EGR-free design. It’s Single Module™ aftertreatment system combines a diesel oxidation catalyst (DOC), diesel particulate filter (DPF) and selective catalytic reduction (SCR) in a system that’s 40% smaller and 20% lighter than Cummins’ Stage IV solution. The 55 kW F3.8 features cooled EGR and does not require the use of AdBlue/Diesel Exhaust Fluid (DEF). An ECO-mode and start-stop functionality facilitate significant fuel and AdBlue/DEF savings, a key benefit considering dump trucks can spend up to 40% of their time running at idle.

“No other manufacturers have produced a new or different solution so far,” said Thorkil K. Iversen, R&D manager at Hydrema. “We have taken our well-proven 912-dump truck and incorporated all its qualities into a smaller version. This means we can now supply a dump truck in the 7 tonne class with excellent all-round visibility, high stability, easy one-step access to the cab and great engine performance too.”

Hydrema’s product range has been 100% powered by Cummins since 2011.
