Fulton Hogan pilots largest Volvo hybrid excavator

23 August 2022:

Fulton Hogan subsidiary Stevenson Aggregates has taken the keys of the first Volvo EC480EL hybrid excavator to be used commercially in the world, and its experience will be part of Volvo’s assessment of the product.

Volvo’s New Zealand distributor, TDX, says Fulton Hogan is a good test bed for technology aimed at reducing carbon emissions.

“Varied types of use, skilled operators and a company willing to innovate are what you need to assess new technology in a working environment,” says TDX Regional Sales Manager, Andrew Falloon.

The EC480EL is Volvo’s largest excavator so far with augmented power. As the boom lowers, a motor feeds energy back to the hydraulic pump via an accumulator.

Stevenson Engineering Operations Manager Ross Ashby says the excavator’s work in Drury Quarry should suit it. Minimal slewing (rotation) beyond 90 degrees means lower energy use and a greater amount of time, proportionally, in regeneration mode.

TDX expects carbon and nitrous oxide emissions will be down by more than 10 percent over the most efficient E series diesel-only excavator. In fuel terms, this would equate to savings of more than 10,000 litres of diesel per year on the EC480EL hybrid.

Stevenson will undertake a full assessment of the new excavator’s performance at the end of August.

Other excavator brands are also producing hybrid alternatives, although mainly using the torsional force of the slewing of the boom for regenerative power.
