Hyster to electrify high capacity lift trucks

Hyster has announced that testing on high capacity lift trucks with electric motors is underway.

The company, which pioneered profitable low emissions with Tier 4/Stage IV diesel engines on its big trucks range, is developing new solutions to achieve profitable zero emissions by electrifying trucks.

According to the manufacturer, which is currently working on a project to electrify a laden container handler, the new electric trucks are expected to drive efficiency and manage costs as they are being built to match the needs of the specific application.

Previously, the duty cycle of the application drove the power output determination, including factors such as engine power, tractive effort, load capacity and speed.

Brett Schemerhorn, president of Big Trucks, Americas at Hyster, said: “Using a modular approach and innovative technology, applications will soon have maximum flexibility when selecting trucks to provide the best zero emissions solution for their needs. The modular approach to the design will allow flexibility in the onboard power source.”

According to Jan Willem van den Brand, director Big Truck product strategy & solutions at Hyster, the application of electric motors to the big trucks range is based on reaching a balance between the vertical movement of the load and the power take-off in combination with the traction.

This is necessary to ensure efficiency while avoiding oversized electric systems and an “unacceptable range of movement”.

As he added, the use of electric motors brings with it a new set of duty cycle variables to consider, including hours of operation and number of moves, power costs of the use of hydrogen in comparison with electricity, infrastructure set-up costs, and time and cost for charging or refuelling.

Schemerhorn said: “Initial introductions are likely to be based on lithium-ion batteries. However, through our relationship with Nuvera Fuel Cells, we expect that implementation of hydrogen fuel cells will be achieved in the next phase.

“Hydrogen fuel cells will allow for rapid refuelling, increased productivity and longer run time between refills.”
