The dual power of Mantsinen The 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 the Östrand pulp mill near the port of Sundsvall on the Swedish east coast. The company unloads roundwood and wood chips and has also started handling bark. Engbergs has a long history with Mantsinen Group.

Kjell Arne Engberg, CEO of Engbergs, says: “Our relationship with Mantsinen has deepened over the years. In 2003 our first Mantsinen machine went into service and we were very satisfied with the machine, not to mention the technical support we received. No matter where our contact was in the world, 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 Dualpower machine from Mantsinen: a Mantsinen 120 with gantry undercarriage on tracks.

“I am very open-minded towards the development of new technologies,” says Engberg. “We bought a Mantsinen 120 diesel and a Mantsinen 120 with Dualpower. The reason for the machine renewal was that the pulp mill decided to increase production by 100 percent, and we had to resolve the logistics accordingly. In all of our investments, we study the possibility of reducing carbon emissions. We wanted this solution because it combines two advantages: when you reduce emissions, you also reduce costs. It’s a win-win situation. However, we also needed a diesel powered machine as we could not access electricity all around the pulp mill area. Fortunately, the pulp mill was very interested in helping us build the power grid solution.

According to the manufacturer, one of the advantages of the Dualpower material handler is its ease of maintenance. The technology is based on standard components, allowing easy maintenance and normal availability of spare parts. The combination of this technology with the Mantsinen Insight remote monitoring system allows smooth operation and fewer unexpected surprises, Mantinsen said.

The material handler performs well and has reduced the need for maintenance, ”says Engberg. He adds: “The Mantsinen Insight allows the machine to tell you if something is wrong. In the future, I think we might even fix some issues remotely and not on site.

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

“Looking at the last 7 days, we have raised 23,000 [metric tons] operating mainly on electric motor. Our production averaged 435 [metric tons] per hour.”

He adds: “This diesel and electric driven material handler seems to be the right solution for us. We have significantly reduced emissions.
