RailMac 15T Lithium Battery Locomotive

The RailMac 15T lithium battery locomotive, with a self – weight of 15 T, adopts lithium battery as power source. Equipped with a Motor Power of 30 KW*2, it also features an Hourly Traction of 20.92 kN and a Maximum Traction of 39 kN. Lithium batteries have the characteristics of high energy density, high conversion efficiency, no memory effect, no charge-discharge delay, low self-discharge rate, and wide operating temperature range. In particular, lithium iron phosphate batteries have the advantages of non-toxic, non-polluting, good safety performance, long life and wide sources of raw materials, and long life. Its application on locomotives effectively solves the lead-acid battery problems of requiring frequent maintenance, frequent charging and insufficient cruising range in long tunnels.

The company provides customers with comprehensive life cycle services, from design to power system supply, installation and commissioning, to after-sales service, training, and spare parts supply, as well as troubleshooting and overhaul technical support. This full range of services ensures that customer equipment maintains high reliability and long-term operating efficiency during use.

Advantages of 15T Lithium Battery Locomotive

• High-performance Lithium-ion Power: Employs advanced lithium-ion batteries, which offer high energy density. This ensures that the 15T locomotive can operate efficiently even in long-tunnel construction scenarios, effectively solving the problems of frequent charging and insufficient cruising range that plague lead-acid battery locomotives.

• Compact and Maneuverable: With a relatively small self-weight of 15T and a minimum turning curve of 15m, it has excellent maneuverability. It can easily navigate through narrow and complex tunnel spaces, making it suitable for subway and tunnel shield construction with limited space.

• Efficient Motor Power: Equipped with 30KW*2 motor power, it provides sufficient power for traction. The hourly traction of 20.92kN and max traction of 39kN enable it to handle the transportation tasks in construction sites, such as hauling construction materials and equipment.

• Low Self-Discharge and Long-lasting: Lithium batteries have a low self-discharge rate. So, the 15T locomotive can be stored for a relatively long time without significant power loss, reducing the need for frequent charging during non – working periods and improving work efficiency.
