The CJY 20T electric locomotive is a masterpiece engineered specifically for large-scale mining operations, available in two distinct types: underground and open-air. For underground settings, it further divides into two modes: single and double heading locomotives. Each variant incorporates advanced speed regulation via resistors, V-shape rubber springs, and a trio of braking systems: hand-wheel, resistor, and air braking. In the innovative double heading locomotive, synchronized control is achieved through the sophisticated PLC programmable microcomputer, utilizing a three-core shielded cable for seamless operation. The open-air 20-ton variant boasts a fully enclosed design, exuding elegance and reliability, while delivering unmatched tractive power and exceptional speed.
Xiangtan South Electric Locomotive Manufacturing Co., LTD. stands as a distinguished leader in crafting narrow rail electric locomotives tailored for mining and tunnel construction. Nestled by the picturesque Xiangjiang River in Hunan's Xiangtan, the cradle of electric locomotive innovation, the company commenced in the 1980s and has flourished over the past 30 years. The focus has always been on producing explosion-proof, special battery electric locomotives, and industrial mining wiring type electric locomotives and their components. Spanning 50 acres, the company boasts a modern production facility exceeding fifteen thousand square meters, two advanced testing centers, and a comprehensive range of specialized test platforms and tracks. Equipped with over 120 cutting-edge processing and testing machines, and a skilled workforce exceeding 150 employees, including over 50 with senior technical titles, Xiangtan South is fully equipped for research, development, manufacturing, and after-sales service. Recognized as a national coal industry electromechanical equipment sentinel production enterprise by the China Coal Products Group, the company acquired the national ISO9001:2000 certification in 2004, and later the ISO9001:2008 certification in 2009 from the China Quality Certification Center. Their expansive product line, featuring 51 approved battery electric and wiring type electric locomotives, has earned the "Mining Product Safety Sign Certificate" and "Mine Explosion-proof Authentication." The "Ann" series of industrial and mining electric locomotives has secured its place among China's top ten electric locomotive brands. With accolades such as "Hunan Integrity Unit," "Observing Contracts and Keeping Promises," and a "Quality Consistency Award," the company continues to set industry standards.
Currently, the company excels in producing flameproof, special storage battery electric locomotives and industrial mining wiring type electric locomotives. Their progressive speed control systems integrate second-generation IGBT intelligent controllers and frequency conversion speed controllers, with core technologies patented nationally. These intelligent controllers address the limitations of traditional resistance speed controllers and first-generation chopping speed regulation controllers, offering remarkable stability and resilience, significantly reducing energy consumption, ensuring safety and reliability, simplifying operations, and minimizing failure rates. Locomotives equipped with these frequency control systems exhibit exceptional performance, with low failure rates, easy downhill control, robust climbing capability, and exceptional energy savings, earning widespread trust and acclaim in the market. Upholding the motto "Thought Determines the Way Out, Character Crafts Products," and driven by the ethos of "First-class Products, Reasonable Prices, Satisfactory Service," the company is dedicated to delivering the utmost in product quality and efficient, attentive service to fulfill customer needs.
