A platform trolley is a type of wheeled cart or dolly that is used to transport heavy or bulky items. It typically consists of a flat platform with four wheels attached to the bottom, and may also include handles for pushing or pulling. Platform trolleys are commonly used in warehouses, factories, retail stores, and other environments where the movement of large objects is required. They can be manual, operated by a person pushing or pulling the trolley, or they can be electric and powered by a motor.
