Mantsinen Dualpower combines electric, diesel motors

The Mantsinen Dualpower material handler promises mobility, productivity and environmental friendliness.


The Mantsinen Dualpower material handler combines what the manufacturer says are the best features of electric and diesel engines, resulting in mobility, productivity and environmental friendliness.

Swedish company Engbergs Transportsystem AB operates at Östrand pulp mill, near the Sundsvall port on the Swedish east coast. The company is offloading of round wood and woodchips and also has started handling bark. Engbergs has a long history with Mantsinen Group.

Kjell Arne Engberg, CEO of Engbergs, says, “Our relationship with Mantsinen has deepened during the years. In 2003, our first Mantsinen machine was put to use, and we were very satisfied with the machine, not to mention the service support we got. No ma tter where in the world our contact was, they always answered the phone.”

In 2017, Engbergs began discussing Mantsinen’s latest innovation, the Dualpower material handler, with the manufacturer. Engbergs was the first customer to acquire a Mantsinen’s Dualpower machine: a Mantsinen 120 with crawler gantry undercarriage.

“I am very open-minded towards development of new technology,” Engberg says. “We purchased one diesel Mantsinen 120 and one Mantsinen 120 with Dualpower. The reason for the machine renewal l was that the pulp mill decided to increase production by 100 percent, and we needed to solve the logistics accordingly. In all our investments, we look into the possibility of reducing carbon emissions. We wanted this solution because it combines two benefits: when you reduce emissions, you also reduce costs. It is a win-win situation. However, we still needed a diesel-driven machine too, because we could not access electrical power all around the pulp mill area. The pulp mill was luckily very interested in helping us build the power grid solution.”

One of the benefits of the Dualpower material handler is easy maintenance, the manufacturer says. The technology is based on standard components, allowing easy service and normal spare parts availability. Pairing this technology with the Mantsinen Insight remote monitoring system allows smooth operation and fewer unexpected surprises, Mantinsen says.

The material handler works well, and it has reduced the need for maintenance,” Engberg says. He adds, “The Mantsinen Insight lets the machine tell you if something is not right. In the future, I think we could even solve some problems remotely and not on the site.”

In addition to maintenance needs, the Mantsinen Insight also records important data on performance and efficiency. Engbergs has achieved the production increase it wanted with the help of the Mantsinen 120 Dualpower.

“Looking at the last 7 days, we have lifted 23 000 [metric tons] mainly running on electric motor. Our production has been in average 435 [metric tons] per hour.”

He adds, “It seems this material handler with both diesel and electric drive is the right solution for us. We have reduced the emissions enormously.”
