A walkie stacker is a type of powered industrial truck used in the material handling industry for lifting and stacking pallets or skids in warehouses, distribution centers, and retail spaces. Unlike forklifts, walkie stackers are designed to be operated while walking, rather than from a seated position, which makes them more suitable for indoor use in areas with limited space. They typically feature a mast, forks, and a small platform for the operator to stand on or walk behind, and are powered by an electric motor. Walkie stackers provide an efficient and economical solution for moving and elevating loads to a moderate height, especially in applications where full-sized forklifts are impractical.
