A vehicle with a pronged device in front for lifting and carrying heavy loads.
Equipment used for low-level lifting and moving pallets is known as powered pallet jacks. They are also called electric pallet trucks, walkie, single- or double-pallet jacks, or power jacks. Some powered pallet jacks contain a platform for the operator to stand on while moving pallets
A stacker is a machine that combines features of a walkie or walk-behind pallet jack with features of a lift truck where an operator would typically sit or stand while driving like a counterbalanced, reach or straddle lift truck. These combination forklifts are typically referred to as walkie stackers.
