Fuel tanker trucks are heavy - duty vehicles engineered for transporting various types of fuel, including gasoline, diesel, and aviation fuel. These trucks have large - capacity tanks, typically made from durable materials like steel or stainless steel, designed to withstand the pressures and potential corrosive effects of the fuel. To ensure safety, they are equipped with double - walled structures, emergency shut - off valves, and sophisticated leak - detection systems. High - efficiency pumping systems enable rapid and controlled fuel transfer, while accurate metering devices ensure precise volume measurement during loading and unloading. The trucks also comply with strict regulations regarding hazardous material transportation, incorporating features like electrostatic grounding to prevent ignition and fire - suppression equipment to mitigate risks associated with flammable fuels.
