The electric transfer cart, also known as an electric flat car, electric platform cart, trolley, gantry cart, or electric rail cart, is an electric material handling vehicle used within factories. It features a simple structure, ease of use, high load capacity, resistance to dirt and impact, easy maintenance, and long service life. Thanks to its convenience, durability, cost-effectiveness, practicality, and ease of cleaning, it has become the preferred transport solution for frequent short-distance handling of heavy loads within a factory or between factory buildings.
