A pallet dolly, also known as a pallet truck, is a vital piece of ground support equipment used in airports to move cargo and luggage efficiently. The device consists of a flat platform with two or more wheels and a hydraulic system that allows the operator to lift and move heavy pallets with ease. Pallet dollies are designed to fit under standard-sized cargo pallets and can be manually or electrically operated. These dollies are essential for handling cargo in airports, reducing manual labor and increasing productivity.
