The Guoxing RXR-M150GD is a 4-wheel-drive diesel firefighting robot powered by a 46 kW engine driving an all-terrain tracked chassis. It carries a 150 L/s water and foam dual-purpose cannon with a 95 m range, and can connect and drag three high-pressure hoses to position. The wide crawler chassis rotates in place, passes through narrow doors and wall holes, and navigates stairs. Remote control operates beyond 1,000 m range. It includes water mist self-protection, 360-degree monitor rotation, 430 mm obstacle clearance, and environmental gas detection for reconnaissance. Designed for highway and railway tunnel fires, subway stations, underground facilities, large-span plant fires, petrochemical oil depots, and refinery fires in industrial applications.
