GTQ-II Rail Lubricator | Automatic Curve Rail Oiler for Metro & Heavy Haul | QL Railway

What is the GTQ-II Rail Lubricator?

The GTQ-II Rail Lubricator (also known as an automatic rail oiler or curve lubricator) is a self-powered, train-activated system designed to apply precise volumes of lubricant to the gauge face of outer rails on small-radius curves - dramatically reducing lateral wear, screeching noise, and vibration in metro, light rail, and heavy-haul environments.

Unlike manual greasing or electric pump systems, the GTQ-II harnesses the vertical kinetic energy of passing trains to drive its internal gear pump - making it maintenance-light, energy-free, and ideal for remote or electrified sections. Each pass delivers 0.35ml per bolt point, forming a durable, low-friction film over 10–30 meters of rail.

⚙️ How It Works: Kinetic Energy to Lubrication

The GTQ-II's brilliance lies in its passive, train-triggered activation:

Mounting - Installed beneath the rail base via clamp irons and brackets.
Activation - As wheels pass, rail deflection drives the transmission rod → connecting rod → gear pump.
Dispensing - Pump pressurizes lubricant (2.5MPa) → forces it through pipelines → to oil tongue applicator.
Transfer - Wheel flange picks up lubricant → distributes it evenly along 10–30m of rail gauge face.
Protection - Forms a wear-resistant film, reducing friction coefficient by 60–80%.

📈 Operational & Economic Benefits

Deploying GTQ-II isn't just about maintenance - it's a ROI-driven investment:

✅ Reduce Rail Wear by 50–70% - Extends rail life from 5 to 8+ years on R<100m curves.
✅ Cut Noise by 15–25 dB(A) - Critical for urban metro compliance with municipal noise ordinances.
✅ Lower Wheel Flange Wear - Reduces wheelset replacement frequency by 30%.
✅ Zero External Power - No electricity, batteries, or solar panels needed. Fully kinetic.
✅ Low Maintenance - Only requires lubricant refill and annual seal inspection.
✅ Quick ROI - Pays for itself in 12–18 months via reduced rail grinding & wheel costs.
