Type GK3 diesel locomotive is the newly-developed locomotive by Ziyang Locomotive Works to meet the increasing demands on the heavy load traction of China railway. It is suitable for the shunting and transfer operation of 3600-4800 tons freight train in railway depots and stations, mines, steel or metallurgical works, petrochemical plant, sea ports and local railway lines.

    In the locomotive are installed two sets of engine-transmission units, i.e. two Type 12V180ZJ diesel engines(service output 790kW for each)and two Type ZJ2011A hydraulic transmissions. According to the operating requirements one of the units can be stopped to adapt the locomotive to the operating conditions such as low-load or no-load service. Mechanical reversing, electric speed control and pneumatic device for eleminating the tip-to-tip gears during reversing are used for Type ZJ2011A transmission so as to better satisfy the shunting and transfer operation. With walking way at each side, the locomotive has its cab in the middle and the engine-transmission room I and II symmetrically located at the front and rear ends. Running part consists of two sets of interchangeable three-axle bogie with the fuel tank and main reservoir suspended in the center under the bogie. The driver’s cab can provide a better looking-out condition and has good sound and insulation performance. In order to suit for the severe conditions such as high temperature, cold climate, dusty areas etc., the locomotive is provided with high-efficiency engine inlet air filter, air supply purifier and air preheater.

    The locomotive is characterized by heavy haul tonnage, good traction characteristics, flexible reversing, easy operation, reliable service and better adaptability. Up to now, this type of locomotives have been used in some large-scale metallurgical enterprises and won high opinion of the customers.
