Welcome to Xiangtan South Locomotive Manufacturing Co., LTD., a beacon of excellence in the realm of narrow rail electric locomotives for mining and tunnel construction. Nestled alongside the picturesque Xiangjiang River in Xiangtan, Hunan, the birthplace of electric locomotives, our company has flourished since its inception in the early 1980s. For over three decades, we have passionately dedicated ourselves to crafting explosion-proof special type battery electric locomotives and robust industrial and mining wiring electric locomotives and their components. Spanning a vast area of 50 mu, our facility boasts more than fifteen thousand square meters of modern production workshops, dual testing centers, a comprehensive professional testing platform, and tracks. Our arsenal includes over 120 pieces of advanced processing equipment and testing apparatus. Our team of over 150 dedicated professionals, including more than 50 with senior technical titles, excels in research, development, manufacturing, and exceptional after-sales service. We are proud to be a national coal industry electromechanical equipment sentinel production enterprise, approved by China Coal Products Group Company. In 2004, we achieved national ISO9001:2000 quality certification, which was further elevated in 2009 by the China Quality Certification Center to ISO9001:2008 standards. Our illustrious battery and wiring electric locomotive series, comprising 51 products, have garnered safety certificates and mine explosion-proof authentication from relevant state departments. Our esteemed 'The Ann' series of industrial and mining electric locomotives has been honored as one of China's top ten electric locomotive brands. In recent years, our unwavering commitment to integrity has earned us accolades such as 'Hunan Integrity Unit,' 'Observing Contracts and Keeping Promises,' and 'Quality Is Stable Qualified Unit.'
At the forefront of innovation, we proudly present our cutting-edge flameproof special type storage battery electric locomotives and industrial and mining wiring type locomotive speed control systems. Harnessing the power of the second generation IGBT intelligent controller and frequency conversion speed controller, these systems are underpinned by pivotal technology now submitted for national patent. These intelligent controllers effectively resolve the shortcomings of traditional resistance speed controllers and first-generation chopping speed regulation controllers, ensuring stable performance, reducing electronic component burnout, and delivering substantial energy savings. They are lauded for their safety, reliability, ease of operation, and low failure rate. Locomotives utilizing this frequency control technology boast an extraordinarily low failure rate, effortless downhill control, formidable climbing power, and remarkable energy efficiency, earning them trust and acclaim in the market. We proudly adhere to our enterprise philosophy: 'Thought Determines the Way Out, Character Casts Products.' Driven by our mission of 'First-Class Products, Reasonable Price, Satisfactory Service,' we pledge unparalleled product quality and exemplary service to fulfill customer expectations.
