Simple technology using the boom-down motion charges an energy-storing accumulator to relieve the torque requirement from the engine.
The hydraulic hybrid uses ‘free’ energy generated by the boom down motion and uses it to reduce fuel consumption.
All this simple and uncomplicated capability takes load off the engine and in the process delivers up to 15% lower fuel consumption and 12% less CO₂ emissions than a conventional machine. When used in high production ‘dig and dump’ applications - especially those within a 90° swing - the fuel saving payback is approximately two years – and all with no loss of performance.
Not only is the idea simple – the componentry is too – consisting of just a few add-on components that are simple to maintain. At this time, the hybrid system is not availble for aftermarket installation.
Technologies such as this are another example of Volvo CE delivering on its commitment to innovate and develop more sustainable and cost effective solutions for customers.
Discover the Volvo unique hydraulic hybrid technology on our EC300E, that utilizes the boom down motion to support the hydraulic pump. This results in 12% to 17% better fuel efficiency while adding no risk for unplanned downtime or reduced performance.
