Product Name:CKD7C Diesel Locomotives for Congo (K) 
Product Description:

CKD7C type diesel locomotive is designed for Congo (K) mainly used on main lines or transfer operation as the important product to expand African railway market. This locomotive is equipped with a well-proven and reliable power propulsion system composed of Caterpillar CAT3512B electric injection diesel engine, JF205H main alternator and the ZQDR310 traction motor, etc. and the propulsion system has been defined as one of the standard pattern for exporting locomotives. Furthermore, a kind of new Co bogie for narrow gauge has been self-developed according to the gauge feature of the Africa which adapted to the R80m radius curve negotiation requirement. The maximum speed of the locomotive is 100km/h, the power rating of the diesel engine is 1340kW (1800HP). The locomotive has functions of double-heading and dynamic brake.
