Ringing in the Year of the Horse with Smarter Power: Our Custom 5 t Lithium-Ion Mine Locomotive Head

As we welcome the Lunar New Year 2026—the Year of the Horse, a symbol of strength, endurance, and unstoppable momentum—our factory is proud to announce a milestone shipment. A fully customised 5‑tonne battery locomotive, powered by lithium‑ion technology, has completed its factory tests and is now ready to depart for a leading mining operation in South America.

Built to Proven Standards, Elevated by Lithium

This locomotive, model CTY5/6,7,9G(B), is engineered to the exact same mechanical footprint and performance parameters as our trusted lead‑acid series. It maintains an adhesive weight of 5 tonnes, fits 600, 762 or 900 mm track gauges, and delivers 7.06 kN traction (12.26 kN max) with a speed of 7 km/h. Twin 7.5 kW motors, a 90V system, and a 385 Ah lithium‑ion battery pack provide the muscle to haul multiple ore cars day after day. Dimensions—2860 mm (L) × 920–1220 mm (W) × 1550 mm (H)—and a 6 m minimum turning radius ensure seamless integration with existing mine infrastructure.

Why Lithium? A Clear Advantage Underground

By swapping lead‑acid for lithium, we unlock benefits that directly improve mine productivity and working conditions:

• Faster opportunity charging – Lithium accepts high‑current charging during shift breaks, keeping the locomotive in service longer.

• 3× longer cycle life – Reduced battery replacement frequency lowers total cost of ownership.

• Truly maintenance‑free – No watering, no acid top‑ups, no corrosive fumes.

• Consistent power output – Voltage stays flat throughout discharge, delivering steady torque even at low state of charge.

• Lighter, yet fully ballasted – The battery weighs less, but we add ballast to preserve the 5‑tonne adhesive weight for maximum traction.

• Intelligent Battery Management System (BMS) – Monitors cell health, temperature, and balance for absolute safety underground.

Testing That Leaves Nothing to Chance

Before being carefully crated for its voyage, this unit underwent extensive off‑rail testing—wheels elevated, drivetrain spinning freely—to validate every controller command and motor response. Watch the video below to see the CTY5(Li) in our workshop, proving its reliability before it ever sees a South American tunnel.

A New Year, A New Standard

This shipment is more than a product delivery; it is a promise. A promise that innovation can respect tradition, that cleaner technology can work within proven platforms, and that no distance is too great when partners share a vision for efficient mining.

As the Year of the Horse gallops in, we extend our warmest wishes to our South American colleagues. May your new locomotive bring you power, safety, and prosperity for many cycles to come.
