The CJY 20T electric locomotive is meticulously crafted for expansive mining environments, available in two distinct types: underground and open-air. For the underground variant, there are further options of single and double heading locomotives. Each model features advanced speed regulation via resistors and a V-shaped rubber spring, complemented by a trio of braking systems: hand-wheel, resistor, and air braking. The double heading locomotive boasts synchronized control via a PLC programmable microcomputer, utilizing a robust three-core shielded cable. The open-air 20-ton locomotive is housed in a completely enclosed design, offering not only a sleek and refined appearance but also unparalleled reliability, formidable tractive power, and impressive speed capabilities.
Xiangtan Southern Electric Locomotive Manufacturing Co., Ltd. stands as a beacon of excellence in the production of narrow-gauge electric locomotives, specializing in mining and tunnel construction. Nestled by the picturesque Xiangjiang River in Hunan, Xiangtan—the birthplace of electric locomotives—this esteemed company has been a trailblazer since its inception in the early 1980s. With over thirty years of rich legacy, the company has honed its expertise in explosion-proof battery electric locomotives and industrial mining wiring types, along with their accessories. Spanning an area of 50 mu, the facility boasts modern workshops exceeding fifteen thousand square meters, two test centers, a comprehensive test platform, and track. Equipped with over 120 state-of-the-art processing and testing apparatus, the workforce of over 150 includes more than 50 individuals with senior technical titles, ensuring a seamless blend of research, development, manufacturing, and after-sales support. Recognized by the China Coal Products Group as a sentinel production enterprise for the national coal industry, the company achieved ISO9001:2000 certification in 2004 and further ISO9001:2008 certification in 2009 by the China Quality Certification Center. The company's extensive product lineup—comprising two major series of battery and wiring-type electric locomotives with 51 products—has earned approvals and certifications for 'Mining Product Safety Sign Certificate' and 'Mine Explosion-proof Authentication'. Its illustrious 'Ann' series has been honored among China's top ten electric locomotive brands. Recently, the company received accolades as a 'Hunan Integrity Unit', 'Contract-Honoring and Promise-Keeping Unit', and 'Quality Stable Qualified Unit'.
Currently, the company pioneers in producing flameproof special type storage battery electric locomotives and industrial mining wiring type models, integrating a cutting-edge speed control system with second-generation IGBT intelligent controllers and frequency conversion technology.
