A straddle stacker is a type of manual or electric material handling equipment used primarily in warehouses and distribution centers for lifting, moving, and stacking pallets. Distinctive for its U-shaped base, which "straddles" the load, the straddle stacker offers enhanced stability during operation. It is designed to handle pallets of various sizes without the need for bottom beams, making it versatile in handling different types of loads. Typically, the straddle stacker is suitable for use in tighter storage spaces due to its compact design, allowing operators to maneuver efficiently through narrow aisles while safely stacking pallets at various heights.
