Technology from super sports cars adds power to Logset’s new harvester

Logset presented the world’s first series-manufactured hybrid harvester at Elmia Wood. For short periods the engine package can deliver 510 horsepower.

“It gives more power in the forest and also reduces fuel consumption,” says Pascal Rety of Logset.

 

The world’s first hybrid-mode harvester had its world premiere at Elmia Wood. The Logset 12H GTE uses technology from super sports cars.

The Logset 12H GTE was presented as a real monster machine. It weighs 24.5 tonnes and is the biggest harvester developed so far by Logset. Rety explains why it is the largest machine to be equipped with hybrid engine technology so far:

“The technology takes up space and costs a lot. That’s why it’s best suited right now for big machines.”

The technology is similar to the solution used by manufacturers of super sports cars to squeeze out even more performance from their engines. Between the engine and the transmission sits a combined electric motor and generator. Instead of batteries it has super capacitors, which store the generated energy and release it immediately there is a need for extra power.

This enables Logset to use a smaller diesel engine of 7.2 litres instead of the 9 that would be normal in this size of harvester. Because the electric drive cuts in when extra power is required, the diesel engine can also be run more smoothly with less fuel consumption.

“Our tests show that this hybrid solution reduces fuel consumption by half a litre per cubic metre of felled timber,” Rety says. “Compared with a diesel engine of 9 litres, that’s a 25 percent saving.”
