Power pallet trucks, also known as electric pallet trucks or powered pallet jacks are power-driven to allow lifting and moving of heavier and stacked pallets over longer distances.

How does an electric pallet truck compare to a forklift?

An electric pallet jack is like a welterweight boxer - compact and quick. It's perfect for lighter loads (up to ~4400 lbs) and is a breeze to maneuver. Now, a forklift is your heavyweight champion. It lifts heavier, stacks higher, can drive on a variety of terrains, and can even load trucks.
