Big Joe Forklifts has launched the WS25-40 High Performance Lithium-ion Stacker, a walkie straddle stacker engineered to maximize operator productivity in increasingly tight warehouse aisles and fast-paced production environments. It’s been designed with capacities ranging from 2,500 to 4,000 lbs.

The WS25-40 features: a compact design for maneuverability in confined spaces; adjustable fast lift and lower speeds to optimize cycle times; fully proportional controls for load handling; a standard Lithium-ion battery with onboard charger.

The onboard charger supports opportunity charging, allowing fleets to stay productive throughout the day without dedicated charging infrastructure or battery swaps.
