The CJY 20T electric locomotive is ingeniously crafted for both expansive underground mines and open-air operations, offering exceptional adaptability with its dual types. For subterranean use, it further diversifies into single and double heading locomotives, each engineered with utmost precision. Featuring advanced speed regulation using resistors and the innovative V-shape rubber spring, it is equipped with a trio of braking systems: the reliable hand-wheel, efficient resistor, and robust air braking. In double heading configurations, seamless synchronized control is achieved via a PLC programmable microcomputer, utilizing a sophisticated three-core shielded cable. The 20-ton open-air variant boasts a fully enclosed design, exuding elegance and remarkable performance. Its formidable tractive power and high-speed capabilities make it a stellar choice for demanding environments.
Xiangtan Southern Electric Locomotive Manufacturing Co., LTD stands as a beacon of excellence in narrow rail electric locomotive production, primarily catering to the mining and tunnel construction sectors. Nestled along the scenic Xiangjiang River in Hunan Xiangtan, the birthplace of electric locomotives, this esteemed company was established in the early 1980s. With a rich legacy spanning over three decades, it specializes in explosion-proof special type battery electric locomotives and industrial mining wiring type locomotives and their components. Encompassing an expansive area of 50 mu, the company boasts cutting-edge production facilities exceeding fifteen thousand square meters, along with two state-of-the-art testing centers, a comprehensive professional test platform, and tracks. Housing over 120 sets of diverse processing and testing equipment, the establishment is powered by a dedicated team of more than 150 employees, including over 50 individuals with senior technical titles, ensuring comprehensive R&D, manufacturing, and after-sales services. Acknowledged by the China Coal Products Group Company as a sentinel production enterprise for the national coal industry, it achieved national ISO9001:2000 quality certification in 2004 and further enhanced its credentials with ISO9001:2008 standards in 2009. Its remarkable range of battery electric and wiring type locomotives, comprising 51 products across two primary series, has received commendations, including the "Mining Product Safety Sign Certificate" and "Mine Explosion-Proof Authentication." The "Ann" series of industrial and mining electric locomotives have been celebrated as one of China's top ten electric locomotive brands. The company's unwavering commitment to excellence has earned it accolades as a "Hunan Integrity Unit," "Observing Contracts and Keeping Promises Unit," and a "Quality is Stable Qualified Unit."
Currently, the company's production line features the flameproof special type storage battery electrical locomotive and the industrial and mining wiring type electric locomotive, both utilizing a pioneering speed control system. This system integrates the second generation IGBT intelligent controller alongside a frequency conversion speed controller, a groundbreaking technology that has secured a national patent. The intelligent controller effectively addresses the shortcomings of traditional resistance speed controllers and the previous generation of chopping speed controllers, delivering unmatched stability, reduced risk of electronic component burnout, and significant energy savings. It ensures safe, reliable usage, ease of operation, and a commendably low failure rate. Locomotives equipped with this controller offer superior motor speed control, minimal failure rates, smooth downhill management, impressive climbing power, significant energy conservation, and minimal maintenance requirements, earning widespread acclaim and trust from users. Upholding the enterprise philosophy of "thought determines the way out, character casts products," we are driven by the mission of "first-class products, reasonable price, satisfactory service," striving to deliver the highest quality products and most efficient, considerate service to meet customer needs.
