The CJY 20T electric locomotive is meticulously crafted for expansive mining operations, offering two distinct classifications: underground and open-air. The underground variant is further divided into single and double heading configurations. All models incorporate cutting-edge speed regulation using resistors and a V-shaped rubber spring complemented by three robust braking systems: hand-wheel, resistor, and air braking. In the double heading model, synchronized control is masterfully achieved through a PLC programmable microcomputer via a sophisticated three-core shielded cable. The open-air version boasts a fully enclosed design, presenting an elegant appearance, outstanding reliability, and formidable tractive effort along with impressive speed capabilities.
Xiangtan Southern Electric Locomotive Manufacturing Co., LTD, a distinguished leader in narrow rail electric locomotive manufacturing for mining and tunnel construction, is nestled by the picturesque Xiangjiang River in Hunan, Xiangtan—the birthplace of electric locomotives. Established in the early 1980s, the company boasts over three decades of expertise in producing explosion-proof special type battery electric locomotives, industrial and mining wiring type electric locomotives, and their accessories. Spanning an area of 50 mu, it features a modern production facility exceeding fifteen thousand square meters, two state-of-the-art test centers, a comprehensive suite of professional testing platforms and tracks, over 120 sets of processing and testing equipment, and a skilled workforce surpassing 150, including more than 50 senior technical experts. As a certified national coal industry electromechanical equipment production enterprise, approved by the China Coal Products Group Company, the firm achieved ISO9001:2000 certification in 2004 and was later validated by the China Quality Certification Center to the ISO9001:2008 standard in 2009. Producing two major series—battery electric locomotives and wiring type electric locomotives—comprising 51 products, all receiving state-issued 'Mining Product Safety Sign Certificate' and 'Mine Explosion-Proof Authentication.' The revered 'Ann' series of industrial and mining electric locomotives earned the accolade of 'China's Top Ten Brand of Electric Locomotives.' In recent years, the company has been lauded as a 'Hunan Integrity Unit,' 'Contract Observing and Trustworthy Enterprise,' and a 'Quality Stable Qualified Unit.'
Currently, the company pioneers the production of flameproof special type storage battery electric locomotives and industrial and mining wiring type electric locomotives, featuring a sophisticated second-generation IGBT intelligent controller and frequency conversion speed controller—a key technology now filed for a national patent. This intelligent controller resolves the limitations of original resistance speed controllers and first-generation chopping speed controllers, ensuring stable performance, significant energy savings, and heightened safety and reliability with simplified operation and reduced failure rates. Electric locomotives utilizing this advanced frequency control of motor speed demonstrate minimal failure rates, effortless downhill control, enhanced climbing power, remarkable energy efficiency, and minimal maintenance, earning widespread trust and acclaim in the market. Upholding the philosophy of 'Thought Determines the Way Out, Character Casts Products,' and driven by the spirit of 'First-Class Products, Reasonable Prices, Satisfactory Service,' we are committed to delivering the most reliable products and the most efficient, considerate service to satisfy customer needs. We firmly believe that 'Focus Leads to Professionalism,' and are confident that your choice will forge our shared success.
