CK6 Diesel-Hydraulic Locomotive

    Type CK6 diesel locomotive is a narrow-gauge diesel-hydraulic locomotive designed and manufactured by Ziyang Diesel Locomotive Works for Tanzania-Zambia Railways.The locomotive is a 977kW diesel-hydraulic locomotive with 80t adhesive weight, B-B wheel arrangement and 65Km/h top service speed. It is suitable for the shunting and transfer service on the TZR, or the similiar railway line.

    Locomotive car body is of all-welded steel structure with frame supporting and walking way outside. From the front to the rear, there are cooling room, engine room, driver's cab and rear machine room. In the engine room is installed a Cummins KTTA38-L high-speed diesel engine with 60V-angle, 12 cylinders, exhaust turbocharger, direct injection and four strokes.  Type ZJ4014GYC hydraulic transmission acts as the main transmission of the locomotive, which is arranged in the engine room together with engine. When locomotive in traction operation changes from forward to backward, such reverse can be carried out in running by moving the reversing handle. The operation is quick and reliable, especially suitable for shunting operation.  With changeover mechanism available in transmission, it is possible to put the locomotive in either shunting operation or transfer operation through the changeover handle, providing the locomotive with wider speed range.JZ-6 air-vacuum brake equipment is adopted for the locomotive brake system. It can control the train equipped with either air brake system or vacuum brake system.

    In electrical control system, Mitsubishi Series FX2 PLC made in Japan is designed to be the core of control circuit. PLC has been proved to be very reliable after years' service experience.The locomotive is provided with locomotive over-speed protection, engine over-speed protection and dead-man device is also provided.
