The El-forest F14 is a series hybrid involving a smaller diesel engine that drives a generator that, via batteries, provides electric energy to electric motors in the forwarder’s six wheels. The electric hybrid technology in the El-forest F14 has attracted great interest among forest companies due, among other features, to the possibility of reducing fuel consumption by 20-50%, which sharply reduces carbon-dioxide emissions.
The El-forest F14 is lighter than a conventional forwarder of the same size, but can cope with the same load. There is less impact on the forest environment due to a patented frame structure that enables all electric-driven wheels to follow the same track with adapted speed.
The forwarder was developed by El-forest AB with assistance from the Volvo Technology Transfer venture-capital company. It will be on demonstration at the Elmia Wood trade fair in Jönköping, Sweden on 3-6 June, along with a wide range of other forestry machinery from Volvo Construction Equipment, as well as other products from the Volvo Group for the forest industry.
In addition to the significant fuel reduction, productivity and operator environment were prioritized, and consequently, profitability for our customers. The drive technology developed has great potential, since, for example, the diesel engine could be replaced by alternative biofuel engines or even with fuel cells in the future.—Per Wassén, Chairman of El-forest and Investment Director at Volvo Technology Transfer, which is owned by AB Volvo
