Refueler trucks are versatile vehicles used to transfer fuel from storage facilities to various types of equipment, including aircraft, vehicles, and machinery. These trucks come in different configurations, with some designed for specific applications like aviation or ground transportation. They are equipped with fuel - storage tanks, pumps, and hoses, which are carefully selected based on the type of fuel being transported. Safety is a top priority, with features such as leak - detection systems, emergency shut - off valves, and proper ventilation to prevent the accumulation of flammable vapors. Refueler trucks also often incorporate metering devices to ensure accurate fuel dispensing, making them essential for maintaining the operational readiness of fleets and equipment across multiple industries.
