A pallet stacker truck, often referred to as a stacker or walkie stacker, is a compact and versatile material handling vehicle designed for lifting and stacking pallets in a variety of settings, including warehouses, retail stores, and manufacturing facilities. Unlike a forklift, it does not have forks at the front but rather a set of adjustable forks or a platform to handle palletised goods.

The key function of a pallet stacker truck is to lift and stack pallets to optimise storage space, facilitate order picking, or move goods from one location to another. These vehicles are typically designed for walk-behind or rider operation, depending on the model, and are known for their manoeuvrability, making them well-suited for narrow aisles and confined spaces.

Pallet stacker trucks are an essential tool for maintaining organized and efficient inventory management, as they can handle a range of pallet sizes and weights. They come in various configurations, including manual, electric, and semi-electric models, providing options to suit different material handling needs.
