KersTech — a drive train technology firm based in Beaverton, Oregon — is developing a new type of forklift engine that is better suited to the vehicle’s frequent starts and stops.
The TwinTorq engine combines electric and hydraulic torque technologies to extend operational run time. It improves battery energy efficiently and significantly extends a forklift’s driving range because each stop and start is considered a separate recovery event.
Lester Erlston, KersTech’s CEO, said when the prototype engine is completed next year, it will be installed in a Hyster forklift and test driven at a research and test facility in Fairview, Oregon.
“Forklift warehouse drive cycles are ideal for TwinTorq motor systems,” Erlston said. “We see tremendous opportunities for that.”
Other possible uses include city buses, parcel delivery vans, and warehouse handling equipment.
The TwinTorq is being developed at the Oregon Institute of Technology, in Klamath Falls and the research is funded in part by public and private grants totaling $459,000. Contributors include the Transportation Research and Education Center at Portland State University, the trade association Drive Oregon of Portland, the independent Oregon Built Environment & Sustainable Technologies Cener, and the city of Portland development commission.
Hyster-Yale also is sponsoring the research and development with a $40,000 contribution of in-kind services.
