Cummins F3.8 Stage V at the service of Hydrema
It is probably known fact that Hydrema product range is currently 100% Cummins powered and has been since 2011. Now the Danish company decided to take a step forward in this partnership and rely on the F3.8 Performance Series engine, well ahead of Stage V emissions requirements for the 90 kW power rating.
Cummins’ F3.8 Performance Series engine will power Hydrema’s 707G dump truck which is available in two sizes: 90 kW and 55 kW. 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 this year.
A look at Cummins contribution
The 90 kW F3.8 is able to deliver more power and more machine capability with simpler architecture and lower weight resulting from an EGR-free design. The Single Module aftertreatment system, in particular, 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 also facilitate significant fuel and AdBlue/DEF savings, a key benefit considering dump trucks can spend up to 40% of their time running at idle.
Raj Chauhan, Customer Engineering Director Europe at Cummins, said: «We are excited to be working with Hydrema to set new standards for machine performance, lower emissions and improved on-site safety. 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».
Hydrema’s 707G is a new design in the 6-9 tonne dump truck segment. Launched to facilitate new standards of site safety and comply with new UK regulations which aim to reduce dumper accidents on site. The 707G offers the benefits of a larger rear tip articulated dump truck (ADT), but with the compact size of a traditional site dump truck.
Thorkil K. Iversen, R&D manager at Hydrema, added: «No other manufacturers have produced a new or different solution so far. At Hydrema we have taken our well-proven 912-dump truck and incorporated all its qualities into a smaller version. This also means that 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».
