Whether you need a manual or electric pallet jack will depend on the size of the load you want to carry, how high you want to lift it, and how tight the space is where you’re working. Manual pallet jack: These hand-operated models use a hydraulic spring to lift pallets off the ground. They’re best suited for lighter material that’s easier to transport and doesn’t have to be lifted as high. Manual pallet jacks come in several varieties, including models that can be adjusted to handle wider or narrower loads and jacks equipped with a digital scale to display the weight of each load. Electric pallet jack: These battery-powered units save on manual labor, but they’re more expensive and require more training. Instead of using a hydraulic pump to raise and lower their prongs, they perform the task using a powered motor. Because they run on electricity, they need to be recharged between uses. Like manual pallet jacks, electric models come in several varieties.
