Transporters are essential vehicles used in airports for transporting cargo, baggage, and other items. They are designed to handle heavy loads and come in different sizes and types. Some transporters are used for moving luggage and goods from one location to another, while others are used to transport passengers to and from the aircraft. They are also used for catering services, refueling, and maintenance of aircraft. Transporters are typically powered by electric or diesel engines and can be either towable or self-propelled. Overall, transporters play a crucial role in the smooth operation of airports.
