Yale Lift Truck Technologies has announced a factory option for electric forklifts to run on thin plate pure lead (TPPL), lithium-ion and lead-acid batteries. 

The Power Key option, which allows operators to switch between TPPL, lithium-ion and lead-acid batteries, will be available on some of Yale's narrow aisle riders, walkie pallet jacks, rider pallet trucks and sit-down counterbalanced trucks.

The Power Key technology will allow the equipment users to switch between three battery modes: lead-acid; lithium-ion; and TPPL.

Yale Lift Truck Technologies brand manager Brad Long says: “From charging and battery maintenance responsibilities to emissions, lift truck motive power has huge implications for warehouse labour, productivity and sustainability.

“This solution is a direct answer to customer demand for flexibility, equipping warehouses with seamlessly integrated technology that makes it fast and easy to transition among all three battery types.” 

Power Key-enabled forklifts have a battery protection system that triggers a controlled shutdown when the battery reaches full discharge. 

In lithium-ion or TPPL mode, a low battery early warning system also provides the operator with multiple warnings that the forklift needs to be charged.
