Walkie stackers are compact machines used to lift, stack, and transport pallets in tight spaces. They’re ideal for warehouses, retail stores, and small storage areas where larger forklifts can’t easily maneuver, providing an efficient solution for handling materials at lower to medium lift heights.
Big Joe's award-winning line of walkie stackers have set the industry standard since day one. Big Joe offers both straddle stackers with a tight turning radius, as well as counter-balance stackers that have the ability to maneuver in and out of trailers.

Frequently Asked Questions
What is the maximum lift height for Big Joe walkie stackers?
Our stackers offer a variety of mast options, with some models capable of reaching heights up to 194 inches. The specific height depends on whether you choose a non-telescopic, two-stage, or three-stage mast configuration.
What is the difference between a straddle stacker and a counterbalanced stacker?
Straddle stackers use outriggers that "straddle" the pallet for stability, making them perfect for standard pallet racking. Counterbalanced models use internal weights instead of outriggers, allowing them to drive in and out of trailers at loading docks.
Can a walkie stacker replace a traditional sit-down forklift?
In facilities with narrow aisles or lower volume needs, a walkie stacker is often a more maneuverable and cost-effective alternative. However, they are slower than sit-down forklifts and are intended for shorter travel distances within a warehouse.
Are Big Joe stackers suitable for use in cold storage environments?
We offer specialized "cold storage conditioning" packages for many of our stacker models to ensure hydraulic fluids and electronics function correctly. These modifications allow the units to operate in temperatures as low as -20°F without component failure.
How wide do my aisles need to be for a Big Joe walkie stacker?
One of the main advantages of our stackers is their small turning radius, often requiring aisles as narrow as 7 to 8 feet. This allows you to increase your storage density significantly compared to using traditional material handling equipment.
What power options are available for the stacker lineup?
We offer traditional lead-acid batteries for standard use and advanced lithium-ion batteries for high-uptime applications. Many of our smaller stackers also feature integrated 110V chargers that can be plugged into any standard wall outlet.
