The CJY 14T electric locomotive represents a breakthrough in mining innovation, meticulously crafted for large-scale mining operations. Emphasizing compact size and nimble agility, it masters tight curves with ease while delivering impressive speed and robust pulling power. The locomotive boasts a dual-stage speed regulation system, employing both resistance regulation and advanced IGBT chopper technology. With seamless control over starting and braking through direct resistance, it achieves exceptional acceleration. Its substantial overload capacity and low failure incidence ensure effortless operation and maintenance. Equipped with both electric and air brakes, it guarantees reliable and secure performance. Thanks to its IGBT-based stepless speed regulation, the locomotive offers a smooth launch with minimal failure risk, marking it as a cutting-edge, energy-efficient marvel of modern engineering.
