Stacker or Pallet Stacker is the common term

Stacker or Pallet Stacker is the common term of reference for lifting equipment which is commonly used in a warehouse or factory setting. The stacker serves as a halfway house between the pallet truck and the forklift truck, offering a more economically viable option than the costly forklift, in order to provide lifting potential and increase storage capacity. Other names used to describe the stacker are, stacker trucks, stacking trucks, manual stackers, straddle stackers and powered counter balanced reach stackers. The stacker is designed to lift loads to a required height, safely and efficiently, either for storage or to enable the block stacking of stock or pallets, or in order to move heavier loads and safely place them on a surface such as a warehouse floor.
At the lower end of the weight capacity is the Warrior Mini Stacker, designed for lighter stacking requirements. Lift is supplied through the foot operated pump which provides smooth and consistent lift. Lowering is actioned via the spring loaded dead mans release handle. Able to stack loads to a height of 1560mm or 1500mm dependant on model, lift in this model is provided by a hand operated self-sustaining winch system. The range also features the manual stacker, which can safely stack loads up to a weight capacity of 1000Kg to a maximum height of 3000mm, through the hydraulic hand truck operated pump unit, lowering is made safe through the deadmans realise trigger included in the handle.
