Advantages of GQ70 Oil Tank Car
The 70 t loading capacity paired with a 78.7 m³ effective volume delivers exceptional cargo utilization, while the lightweight tare weight of 23.6 t reduces energy consumption per tonne of cargo, lowering long-term transportation costs.
A 0.15 MPa tank pressure rating ensures secure containment of liquid/gaseous cargo, while the 25-year service life and 5-year factory overhaul cycle provide reliable long-term operation and reduced maintenance frequency.
Designed to operate in temperatures from -40°C to +50°C, it maintains stable performance in harsh climates, making it suitable for deployment in polar, desert, and other extreme environmental regions.
A maximum full-load speed of 120 km/h and 145 m minimum negotiable curve radius enable rapid, smooth navigation across main lines and complex regional routes, ensuring timely delivery of time-sensitive liquid cargo.
