Introduction to the WS25-40 High Performance Lithium-Ion Stacker
Big Joe Forklifts has officially introduced its latest material handling solution, the WS25-40 High Performance Lithium-Ion Stacker, a walkie straddle stacker specifically engineered to address the growing demands of modern warehouse and production environments. As facilities continue to compress operational footprints while simultaneously increasing throughput expectations, equipment must evolve to deliver higher efficiency, greater maneuverability, and simplified ownership. The WS25-40 is positioned as a purpose-built response to these operational realities, combining compact design, advanced performance controls, and integrated lithium-ion technology into a single, productivity-focused solution.
Built for Tight Aisles and High-Throughput Operations
Warehousing and light manufacturing facilities are experiencing a fundamental shift in layout strategy. Storage density is increasing, aisle widths are shrinking, and workflow velocity is accelerating. In such environments, every inch of maneuverability and every second of cycle time directly impacts operational performance. The WS25-40 has been developed with class-leading compact dimensions that enable operators to confidently navigate confined spaces without sacrificing lifting capability or control precision. Its streamlined chassis design allows it to operate efficiently in narrow aisles, congested staging zones, and production areas where space optimization is critical. By minimizing the truck’s footprint while preserving strength and stability, Big Joe has created a stacker that supports higher storage density without compromising safety or performance.
Capacity and Performance Engineered for Versatility
The WS25-40 offers a versatile capacity range from 2,500 to 4,000 pounds, making it suitable for a broad spectrum of warehouse tasks including pallet stacking, dock work, rack storage, and line-side replenishment. This flexible capacity range ensures that facilities can deploy the stacker across multiple operational zones, reducing the need for specialized equipment while maintaining performance consistency. Adjustable fast lift and lower speeds further enhance the truck’s adaptability. Operators can fine-tune performance settings to match specific load types and workflow demands, optimizing cycle times while maintaining safe load handling practices. This level of customization helps improve daily throughput without introducing complexity into the operating process.
Fully Proportional Controls for Precision Handling
Precision is a critical requirement in today’s warehouse operations, especially in high-density racking environments where margin for error is minimal. The WS25-40 is equipped with fully proportional controls that deliver smooth, responsive load handling. Rather than abrupt or binary lift functions, operators experience precise, incremental control over lifting and lowering movements. This ensures accurate pallet placement, reduces product damage, and enhances overall operator confidence. In fast-paced facilities where consistency and repeatability are essential, such responsive control systems can significantly improve both productivity and safety metrics.
Integrated Lithium-Ion Power for Modern Fleet Demands
At the core of the WS25-40’s performance advantages is its standard lithium-ion battery system. Unlike traditional lead-acid batteries that require watering, equalization, and scheduled maintenance, the integrated lithium-ion solution eliminates routine battery upkeep. This reduction in maintenance directly translates into less downtime and lower total cost of ownership. The lithium-ion battery also provides consistent power output throughout the discharge cycle, ensuring steady performance during extended shifts. Operators no longer experience performance degradation as battery charge declines, allowing for predictable productivity levels across the workday.
Onboard Charger and Opportunity Charging Flexibility
One of the most impactful features of the WS25-40 is its onboard charger, which simplifies fleet charging infrastructure. Facilities do not need to allocate large, dedicated battery charging rooms or implement time-consuming battery swap programs. Instead, the truck can be plugged into standard power sources whenever downtime naturally occurs, such as during breaks or shift changes. This opportunity charging capability allows operations to maintain high equipment availability without interrupting workflow. By enabling flexible charging practices, the WS25-40 supports continuous productivity and reduces operational bottlenecks associated with traditional charging logistics.
Reducing Downtime and Total Cost of Ownership
Downtime is one of the most significant hidden costs in material handling operations. Whether caused by battery maintenance, equipment servicing, or inefficient workflow design, interruptions directly impact profitability. The WS25-40 addresses this challenge through its maintenance-free lithium-ion battery system and simplified charging process. Eliminating battery watering, acid handling, and lengthy equalization cycles reduces both labor demands and safety risks. Over time, these efficiencies contribute to lower operational expenses and improved asset utilization. The long service life typically associated with lithium-ion technology further strengthens the economic value proposition for fleet managers seeking long-term cost stability.
Designed Around Real-World Operator Challenges
According to Jimmy Anderson, Director of Product Management at Big Joe Forklifts, the WS25-40 was developed with direct input from customers facing daily operational pressures. Tight aisles, rapid production cycles, and increasing throughput targets require equipment that is not only compact but also highly responsive and intuitive. The stacker’s ergonomic layout, smooth control response, and streamlined power management system are all centered on enhancing the operator experience. By reducing complexity and improving responsiveness, the WS25-40 allows operators to focus on productivity rather than equipment limitations. This operator-centric design philosophy reinforces Big Joe’s commitment to practical innovation grounded in real-world application.
Supporting the Industry Shift to Electric Fleets
The material handling industry continues to transition away from internal combustion equipment toward cleaner, more energy-efficient electric alternatives. Lithium-ion technology is playing a pivotal role in accelerating this transformation. The WS25-40 aligns with this broader industry movement by offering an integrated lithium solution that delivers both environmental and operational benefits. Electric equipment reduces emissions, lowers noise levels, and improves indoor air quality, making it ideal for warehouse and production settings. By integrating lithium-ion as a standard feature rather than an optional upgrade, Big Joe demonstrates its commitment to supporting customers as they modernize their fleets.
Enhancing Fleet Standardization and Operational Simplicity
Fleet managers increasingly prioritize equipment standardization to simplify training, maintenance, and parts management. The WS25-40 contributes to this objective by combining multiple advanced features into a single, unified platform. The integration of battery, charger, and performance controls within one compact system reduces the need for auxiliary components or external infrastructure. Operators benefit from consistent equipment behavior, while maintenance teams manage fewer variables across the fleet. This streamlined approach improves operational clarity and supports scalable growth strategies for distribution centers and production facilities alike.
Optimizing Productivity Without Adding Complexity
A key challenge in modern equipment design is delivering advanced performance capabilities without overwhelming users with complicated systems. The WS25-40 achieves this balance by embedding sophisticated lithium-ion and control technologies into a user-friendly platform. Adjustable performance settings enhance efficiency, yet remain intuitive to operate. Opportunity charging adds flexibility without requiring additional infrastructure investment. Proportional controls improve precision without introducing unnecessary learning curves. This harmonious integration of performance and simplicity ensures that productivity gains are accessible rather than theoretical.
