Locomotive Gearbox Company in Rapid Development

Publish Date: 2010-10-26


The locomotive gearbox company, a subsidiary of Nanjing High Accurate Drive Equipment Manufacturing Group Co., Ltd (hereafter referred as NGC), is the R & D and production base of the railway transportation equipment, and the products range covers metro, railroad car, intercity train, high speed train and locomotive, etc. Only the international brand can conquer the domestic market, NGC aimed at the international market at the very beginning, and cooperated with GE, ALSTOM successively. Nowadays, the locomotives equipped with NGC gearings are running on the railway all over the world. 

Unceasing innovation – the foundation of a century-old enterprise

NGC, with more than 40 years history, is becoming the largest manufacturer of transmission equipment in China. It leads the domestic market in its traditional products, such as metallurgy, construction material, mining, hoisting, chemical industry, etc. In recent years, Mr. Hu Yueming, the Chairman and General Manager of the Company put forward the slogan of “the second venture”, and the wind turbine, railway transportation and the marine are the main development trends.

Nanjing High Speed Gear Manufacturing Co., Ltd, the R &D and the production base for the wind turbine gearbox was founded in 2003, and signed the Joint Development Agreement with GE regarding the developing of the special gearbox for GE’s wind turbine generator in 2006. In 2009, the output capacity of our wind turbine gearbox reached about 6300MW, ranked No. 2 in the world market. In marine section, quite a few products bridged the gap of domestic market. In 2010, the tunnel thruster with the maximum power and blade diameter and the very first piece of 3000HP azimuth thruster break up the market monopoly of overseas companies. In railway transportation section, one of the key development strategies is to develop the general gearboxes for railway transportation. At present, a new plant is under construction in Lukou industry district, which can be put into use in 2011. This indicates that NGC reaches a new level in railway transportation area. 

Cooperation with GE

In 2003, GE America was looking for a strategic partner in China, until they found NGC, the excellent domestic transmission equipment manufacturer. A comprehensive investigation was carried out to NGC by GE on several sides including management, R &D and production, etc. In addition, NGC was requested to produce a sample which can meet the requirement of GE quality warranty system. This was the first examination for NGC to become GE’s international supplier. Through our continuous improvement in our management, R &D, and production level, NGC finally won the respect and trust of GE, and was successfully appointed as GE’s international supplier in 2005. Till today, NGC has supplied the traction gears to GE which are running on the railway all over the world including Qinghai-Tibet railway.

Cooperation with ALSTOM

NGC signed the technology cooperation agreement with the famous company ALSTOM in 2007. At the very beginning, NGC did a very big investment of capital and manpower to the development of metro gearboxes, and the first NGC metro gearbox with independent intellectual rights and world advanced technology was successfully developed in July, 2008. The production license for these gearboxes was issued to NGC by ALSTOM FBO Company. The metro gearboxes supplied to ALSTOM are already applied to the extension line 4 of San Diego in Chile. Besides, some other projects are under construction, such as line M5 and M6 in Amsterdam, Buenos Aires project, etc……


Furthermore, 4 units of NGC gearboxes were on-line tested in Shanghai metro Line 1, which bears the maximum load for 7 months, and it showed that everything works well. Today, the volume production is already formed, and the products supplied to customers have run for over 1 year. It proves that the performance of our products reaches the level of similar ones in the world. Our products have already been used successfully in Extension line of Shanghai Line 2, extension line of Nanjing Line 1. We still have Beijing Line 15 and Shenzhen Line 4 ……on our hand.


As the R &D technology of railway transportation becomes more and more mature, NGC begins to co-develop the intercity train gearbox at the speed of 200Km/h with ALSTOM. Batch delivery of goods is aimed to be realized in 2011.

AGV gears at 570km/h

In 2010, a contract about developing and manufacturing AGV gears at speed of 570Km/h was signed between NGC and ALSTOM. 570Km/h- this is the one that ALSTOM is producing for European and American market, and is challenging the international limit of high speed train. Only 2 hours is enough from Beijing to Nanjing according to this speed. Under this flying-like speed, any micro error of any components may result in a disastrous consequence. ALSTOM indicated their high trust to NGC by choosing us to take the job of this core transmission equipment

Nowadays, NGC’s railway transportation gearboxes were awarded 6 national patents. NGC, relying on its eminent management, R &D and manufacturing capability, and the cooperation with ALSTOM on high speed trains, will definitely have its own glory in railway transportation section.
