The CJY 20T electric locomotive has been designed specially for large size mine, it contains two types,i.e, underground and open air; for underground type, there also has two modes, i.e single and double heading locomotive. All of them adopt speed regulation with resistor and V-shape rubber spring as well as three braking systems: hand-wheel, resistor and air braking. In double heading locomotive, its synchronized control can be realized by means of the PLC programmable microcomputer and through a three-core shielded cable. The open-air type 20ton locomotive employs a totally-enclosed construction, it has an elegant appear-ance, reliable performance and powerful tractive effort as well as high speed etc.features.
Xiangtan southern electric locomotive manufacturing co., LTD . Is mine, construction of tunnel with narrow rail electric locomotive professional manufacturers, is located in the beautiful xiangjiang river, electric locomotive originate land-hunan xiangtan. The company was founded in the early 1980s, it has been 30 years of history, has focused on production explosion-proof special type battery electric locomotive, industrial and mining wiring type electric locomotive and its accessories. The company covers an area of 50 mu, with modern production workshop more than fifteen thousand square meters, test center two and a full set of professional test platform and track, all kinds of processing equipment, testing equipment more than 120 sets, the staff of morethan 150 people, including senior technical titles has staff more than 50 people, research and development, manufacturing andafter-sales condition complete. The company is China coal products group company approved for the national coal industry electromechanical equipment sentinel production enterprises; 2004 through the national ISO9001:2000 quality certification, and in 2009 by the China quality certification center according to ISO9001:2008 standard through in version of the authentication. The company produces the battery electric locomotive product series and wiring type electric locomotive 2 big series 51 products have passed the relevant state department approval to issue "mining product safety sign certificate" and "mine explosion-proof authentication"; The company produces "the Ann" series of industrial and mining electric locomotive was awarded China famous electric locomotive top ten brand". In recent years, the company has been rated as "hunan integrity unit", "observing contracts and keep promise in unit", " quality is stable qualified unit".
At present, the company produces the flameproof special type storage battery electrical locomotive and industrial and mining wiring type electric locomotive speed control system is used to design the second generation IGBT intelligent controller and frequency conversion speed controller, its key technology has been declared national patent. The intelligent controller for the original resistance speed controller and the first generation of chopping speed regulation controller defect and the insufficiency, has stable performance, is not easy to burn out electronic components, energy saving significanty, the use of safe and reliable, simple operation, low failure rate. Using this kind of controller of frequency control of motor speed electric locomotive has failuer rate bottom, downhill easy control, climbing force is big, energy saving is remarkable, and the small amount of maintenance etc, and into the market by the users trust and praise. We adhering to the "thought determine the way out, character casting products" enterprise idea, in the spirit of "first-class products, reasonable price, satisfactory service" business purpose, with the most reliable quality of products, the most efficient considerate service to meet customer needs. We believe that "because focus , so professional", more believe that your choice will cast our common brilliant.
