Tankers at airports around the world have to bring their A game every day. Closely timed flight schedules and strict safety regulations determine the everyday workload for vehicles and drivers. The Brazilian firm Rucker specializes in the equipping of airplane tanker trucks, and just completed a large project for Infraero, Brazil's national airline.
At most large airports, passenger and cargo planes are supplied using underground jet fuel pipelines. An Airbus A380, for example, can take on up to 310,000 liters of fuel, while an average tanker truck can only hold 40,000 liters. Fueling from tankers would obviously take a long time, which is why airports employ so-called hydrant dispensing trucks. They pump the jet fuel from the pipelines to the planes. In addition to enormous savings in time, this method also reduces the risks associated with mobile jet fuel tanks. It looks easy when the specially-trained airplane fuelers expertly connect hoses and control the fueling using remote control; however, this simplicity cloaks a complex technical system. Among other functions, the tankers remove the fuel from the underground pipelines, which are pressurized to 10 bar, and reduce the pressure to 3.5 bar. If the pressure is too high, then the tanks in the wings of the plane could be damaged. Hydrant dispensing tankers can start, monitor, and end the entire fueling process. Rucker provides the automation and regulation technology for these demanding applications.
