RailMac 25T Lithium Battery Locomotive

The RailMac 25T lithium battery locomotive, with a self-weight of 25 T, adopts lithium battery as power source. Equipped with a Motor Power of 75 KW*2, it also features an Hourly Traction of 65 kN and a Maximum Traction of 74 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 25T Lithium Battery Locomotive

• Long-life Battery System: Lithium batteries, especially lithium iron phosphate batteries, have a long service life and a wide range of raw materials. For the 25T locomotive, this means lower replacement costs and longer-term use, reducing the total cost of ownership in construction projects.

• Optimal Track Compatibility: With a track gauge of 762/900mm, it is compatible with common track systems in subway and tunnel construction. The 2600mm wheelbase and 840mm wheel diameter ensure stable operation on the track, reducing the risk of derailment and improving operational safety.

• Powerful Traction for Heavy Loads: 75KW*2 motor power, hourly traction of 65kN, and max traction of 74kN allow it to handle heavier loads in construction, such as transporting large – scale shield machine components, which is crucial for improving construction efficiency.

• Wide Operating Temperature Range: Lithium batteries have a wide operating temperature range. This enables the 25T locomotive to work normally in different temperature environments in tunnels, whether it is a relatively high-temperature environment during continuous construction or a low-temperature environment in some underground areas.
