Discover the robust and exceptionally crafted CJY 20T electric locomotive, a marvel designed meticulously for large-scale mining operations. This versatile powerhouse is available in two configurations: underground and open-air. The underground variant offers two modes: single and double-heading, providing flexibility for various needs. Equipped with advanced speed regulation through resistors, V-shaped rubber springs, and an impressive trio of braking systems—hand-wheel, resistor, and air braking—this locomotive guarantees unparalleled safety and performance. The double-heading model features synchronized control powered by a state-of-the-art PLC programmable microcomputer, seamlessly linked via a three-core shielded cable. Meanwhile, the open-air model features a completely enclosed design that exudes elegance and reliability, ensuring powerful tractive effort, high speed, and unmatched performance.
Welcome to Xiangtan Southern Electric Locomotive Manufacturing Co., LTD., a premier manufacturer of specialized electric locomotives for mining and tunnel construction. Nestled in the picturesque vicinity of the Xiangjiang River, in the birthplace of electric locomotives—Hunan Xiangtan—our legacy began in the early 1980s. With over 30 years of expertise, we have honed our focus on producing explosion-proof battery electric locomotives and industrial mining wiring type locomotives, along with their accessories. Our sprawling 50 mu facility boasts over fifteen thousand square meters of modern production workshops, two state-of-the-art test centers, and comprehensive testing platforms and tracks, supported by over 120 sets of sophisticated processing and testing equipment. With a dedicated workforce of over 150, including more than 50 senior technical experts, we excel in R&D, manufacturing, and customer support. Recognized by the China Coal Products Group as a sentinel production enterprise for national coal industry electromechanical equipment, we achieved prestigious ISO9001:2000 quality certification in 2004 and were further validated by the China Quality Certification Center in 2009 under the ISO9001:2008 standard. Our portfolio includes two major series—battery electric locomotives and wiring type electric locomotives—featuring 51 products, all certified for mining safety and explosion-proof standards. Our 'Ann' series of industrial and mining electric locomotives proudly ranks among China's top ten electric locomotive brands. In recent years, we have earned accolades as a 'Hunan Integrity Unit,' recognized for 'Observing Contracts and Keeping Promises,' and maintaining 'Stable Quality Standards.'
Currently, our company pioneers the production of flameproof specialized storage battery electric locomotives and industrial mining wiring type electric locomotives, equipped with cutting-edge speed control systems. These systems are engineered with second-generation IGBT intelligent controllers and frequency conversion speed controllers, for which key technologies have been patented nationally. These intelligent controllers address and rectify the deficiencies of original resistor speed controllers and first-generation chopping speed regulation controllers. They offer stable performance, enhanced durability of electronic components, significant energy savings, safety, reliability, user-friendly operation, and low failure rates. Our frequency-controlled electric locomotives, utilizing these advanced controllers, exhibit minimal failure rates, easy downhill control, impressive climbing capability, and marked energy conservation, earning the trust and praise of our users. We embody the enterprise philosophy of 'Thought Determines the Way Forward, Character Shapes Products,' driven by the mission of 'First-Class Products, Reasonable Prices, Satisfactory Service.' By delivering the most reliable quality products and the most efficient, considerate service, we strive to exceed customer expectations. We firmly stand by the belief that 'Focus Makes Us Professional' and are convinced that your choice of our products will forge a path to mutual brilliance.
