CKD CoCo 1000 kW SIX-AXLE MOTOR LOCOMOTIVES

Tradition

Six-axle motor locomotives intended for heavy shunting and pulling services have a tradition of over 30 years at CKD LOKOMOTIVKA. Of the over 13,000 motor locomotives manufactured, almost 8,000 are six-axle locomotives with electrical power transfer.

The prototype of a six-axle locomotive was produced in 1963. The fact that this type of locomotive has been in demand for already 30 years now testifies to the simplicity and reliability of its design, which was of course constantly evolving and being perfected, while preserving maximum inheritance and interchangeability of its main nodes.

In many European and Asian countries, locomotives operate under extreme climactic conditions. For example, beyond the Arctic Circle (in Vorkut) and in Siberia (the Baikal-Amur Highway) they work at -50 C, and on the other hand in the deserts of Turkmenistan, Syria and Iraq at temperatures of +45 C. A total of 7854 six-axle locomotives in ten various variations have been manufactured at CKD:

Technical Description

Zvtit
The 5000th CME 3 locomotive for the USSR

This motor locomotive with 1000 kW output with electrical DC power transfer is of hood unit type. The main frame is anchored on two three-axle undercarriages. The diesel tank hangs between the bogies on the underside of the frame. If the locomotive is equipped with an electrodynamic brake, space is left inside the tank for batteries. The operator's cab is located between the front and short rear hood. The engine compartment contains a six-cylinder inline diesel engine with a DC traction generator, cooling block, a hydromechanical transmission, brake compressor, and traction motor cooling ventilators. The rear hood contains an electrical distributor and electrodynamic brake. Built into the front of the main frame is an automatic coupler or coupling assembly as per the customer's wishes. The locomotive is equipped with the latest features, which heighten its technical performance while at the same time decreasing the user's costs. The degree of installed facilities of the locomotive depends on the customer.
