The CJY 7T electric locomotive is an exceptional choice for large mines, boasting a design that is both compact and robust. Its remarkable features include a short wheelbase, excellent body rigidity, superior buffering performance, minimal mechanical wear, and step-less speed regulation that eliminates arcing during operation. The locomotive is renowned for its high reliability, low failure rate, and rapid current protection capabilities, all while promoting energy efficiency. This powerhouse of a locomotive employs variable frequency speed regulation, leveraging AC variable frequency motor traction to ensure low maintenance costs and a broad spectrum of speed control options. Operating this machine is both straightforward and safe, and it is furnished with three distinct braking methods: mechanical, electrical, and air, offering unparalleled control.
Xiangtan South Locomotive Manufacturing Co., Ltd. stands as a premier manufacturer of electric locomotives tailored for mines and tunnel construction, specializing in narrow rail designs. Nestled by the picturesque Xiangjiang River in the cradle of electric locomotive innovation—Xiangtan, Hunan—the company has been a beacon of excellence since its inception in the early 1980s. Encompassing an extensive 50 mu, the facility boasts over 15,000 square meters of cutting-edge production workshops, two advanced test centres, and a comprehensive array of professional testing platforms and tracks. With a robust fleet of more than 120 pieces of processing and testing equipment, the company prides itself on a talented workforce exceeding 150 individuals, including over 50 with senior technical titles, ensuring complete proficiency in research, development, manufacturing, and after-sales support. Recognized by the China Coal Products Group Company, it holds a prestigious position as a sentinel production enterprise for the national coal industry’s electromechanical equipment. Successfully certified under the national ISO9001:2000 standard in 2004, and later to the ISO9001:2008 standard in 2009 by the China Quality Certification Center, the company’s offerings—spanning two major series and 51 products—are approved with the 'Mining Product Safety Sign Certificate' and 'Mine Explosion-proof Authentication.' Notably, their 'Ann' series was celebrated as a top ten electric locomotive brand in China. Recent accolades include 'Hunan Integrity Unit,' 'Observing Contracts and Keeping Promises Unit,' and 'Quality Stable and Qualified Unit.'
