A baggage tug is like a big car that helps move heavy bags and luggage around at an airport. Think of it like a wagon that can pull heavy suitcases and bags from one place to another.
The baggage tug is usually driven by a person who sits in the driver's seat and uses a steering wheel and pedals to control it. The driver can also use gears to make the baggage tug go fast or slow, depending on where it needs to go.
The baggage tug has a flat area behind the driver's seat where the luggage can be loaded onto. This area is called a tow bar, and it looks kind of like a big, metal platform. The tow bar can be raised or lowered, so that bags and suitcases can be loaded onto it or removed from it easily.
Once the luggage is loaded onto the tow bar, the driver of the baggage tug can drive it around the airport. They can drive it up to the plane, so that the bags can be loaded onto the plane, or they can drive it to the baggage claim area, so that people can pick up their bags after they land.
Overall, the baggage tug is an important tool that helps make it easier for people to travel and move their luggage around an airport.
