The design of diesel locomotives ChME3 provides for operation on a system of two units with the possibility of equipping the diesel locomotive with a portable remote control for servicing by one person.
The diesel locomotive is equipped with a 6-cylinder, in-line Czechoslovakian diesel engine type K6S310DR with turbocharging with a total power of 993 kW (1350 hp) with a traction generator TD802 with a power of 885 kW, which form a power unit, the energy of which is used to obtain traction force. The power plant allows the diesel locomotive to develop maximum traction force in train mode up to 23 t/s and in shunting mode up to 28 t/s.
The control cabin has a basic configuration and is equipped with two control panels, a hand brake, a ventilation unit, a heating coil, floor heaters, a speedometer and safety devices.
At the request of the client, other retrofitting and modernization of the diesel locomotive can be carried out according to the technical specifications provided by you and the cost of these works agreed upon.
During 2023 – 2024 the diesel locomotive underwent a complete overhaul in accordance with the current instructions and rules for diesel locomotives of this series, namely:
- complete overhaul of a diesel engine with the replacement of 90% of spare parts and components with new ones, including the connecting rod and piston group (crankshaft bearing shells, piston rings, cylinder liners, valves and valve guides, etc.), turbocharger, regulator speed, fuel equipment and more;
- complete overhaul of the traction generator with replacement of armature bearings, repair of main and additional poles, grinding and refurbishment of the armature commutator, replacement of insulators, brush holders and brushes;
- complete overhaul of traction motors TE006 and two machine units DT701/706 with repair of anchors, main and auxiliary poles, repair of commutators, repair of brush holders and their components;
- complete overhaul of the brake compressor K2Lok-1;
- complete overhaul of the chassis, namely repair of bogie frames, brake-lever transmission, brake cylinders, hydraulic vibration dampers, etc. with the replacement of all necessary spare parts and components;
- full inspection of wheel sets with replacement of tires and inspection of axle box units of the 2nd volume in accordance with the requirements of instructions VND32.0.07-001-2001 and TsT-0165;
- complete repair of auxiliary equipment: overhaul of the refrigerator shaft with replacement of water collectors and cooling sections, upper and side louvers of the refrigeration unit and their drives, hydromechanical gearbox, drive shafts with clutches of the main fan and hydromechanical gearbox, repair of cooling fans of the main and additional cooling circuits. Manufacturing of new expansion tanks;
- complete repair of impact coupling devices in accordance with the requirements of Standard STP 04-105:2018
- complete overhaul with replacement of insulation and internal lining of walls and ceilings, shells, baseboards and other decorative elements in the control cabin.
- complete repair of brake and pneumatic equipment in accordance with the requirements of the TsT-0058 instruction;- external inspection and hydraulic testing of air tanks in accordance with the requirements of the instructions TsT-TsV-TsL-TsP-0050;
- complete replacement of high-voltage and low-voltage electrical wiring, repair and partial replacement of electrical equipment with new ones, complete repair and restoration of the main and auxiliary control panels;
- a complete set of new pipelines for water, oil, fuel and pneumatic systems were manufactured.
The diesel locomotive is equipped with a new battery type 56TN-150saU2 manufactured by the “Vladar” plant, Bulgaria.
In May 2023 specialists from NPP UKRTRANSAKAD LLC, Dnepr, carried out work to inspect the technical condition of the main load-bearing structures of the diesel locomotive (body frame and bogie frame) with the issuance of a technical solution to extend the service life of the diesel locomotive by 6 years (until 04.2029). All documentation for extending the service life of the diesel locomotive – “Agreement on the provision of services for monitoring the technical condition of the main load-bearing structures” and “Technical solution for extending the service life of the diesel locomotive UTA-15-23/s dated 05/09/2023.” Is in stock.
The diesel locomotive underwent commissioning, full rheostatic tests and running-in on the access roads of a specialized repair enterprise. Completely ready for use.
Work was carried out to completely paint the locomotive externally and internally using high-tech and expensive paints and varnishes from the German brand Lankwitzer Gmbh in accordance with the selected color palette and painting scheme.
A two-tone blue-blue exterior paint scheme was chosen using two-component enamels: RAL 5015 – sky blue as the main color and RAL 5012 blue as an additional color. The combination of sky blue and light blue colors of the main scheme of the locomotive is harmoniously complemented by white elements in RAL 9010 color in the form of narrow stripes – along the roof line turning into a triangle on the front part and along the hood floor line, as well as a wide stripe at the level of the lower flaps of the refrigeration shaft with exiting to the frontal part and a sharp zigzag upward on the side surface of the hood. The roof of the locomotive is painted metallic gray in RAL 7047 Telegray 4.
Separate elements of the external paint scheme are specially shaped signal strips on the front and rear of the locomotive, a strip on the fuel tank that is painted in traffic yellow RAL 1023, as well as track clearing devices at the front and rear that are painted in traffic red RAL 3020.
The basic painting scheme is complemented and harmonized by individual elements painted in white RAL 9010 – the axle box covers and the fuel tank. The crew part is painted in practical black RAL 9004 – signal black.
