Introducing the CJY 20T electric locomotive, a marvel of engineering crafted specifically for the demanding environments of large-scale mines. This versatile locomotive is available in both underground and open-air configurations, with the underground version further offering single and double heading options. Every model benefits from advanced speed regulation via resistor and V-shape rubber springs, alongside a trio of braking systems: hand-wheel, resistor, and air brakes. In the double heading variant, synchronized control is masterfully achieved through a sophisticated PLC programmable microcomputer, seamlessly connected via a three-core shielded cable. The open-air model boasts a fully-enclosed design that enhances its aesthetic appeal while delivering exceptional performance, robust tractive power, and impressive speed capabilities.
Xiangtan South Locomotive Manufacturing Co., LTD stands as a beacon of excellence in the niche of narrow rail electric locomotives for mines and tunnels. Nestled along the scenic Xiangjiang River in Hunan Xiangtan—the birthplace of electric locomotives—our company has been a leader since its inception in the early 1980s. With over three decades of experience, we specialize in explosion-proof battery electric locomotives and industrial, mining wiring type electric locomotives and accessories. Our sprawling facility spans 50 mu, encompassing modern production halls exceeding 15,000 square meters, dual testing centers, a comprehensive testing platform, and track systems. Equipped with over 120 pieces of advanced processing and testing equipment, our dedicated team of more than 150 professionals includes over 50 senior technical experts, ensuring seamless R&D, manufacturing, and after-sales support. As a recognized enterprise by the China Coal Products Group for the national coal industry's electromechanical equipment, we achieved the national ISO9001:2000 quality certification in 2004 and were further accredited by the China Quality Certification Center in 2009 under ISO9001:2008 standards.
