Heavy Locomotive Overhaul (Standards KR-1 / KR-2)
JSC Elmavalmshenebeli delivers comprehensive factory-grade capital overhauls (KR-1 and KR-2 specifications) for mainline freight, passenger, and industrial electric locomotives. Our certified remanufacturing processes fully restore OEM technical tolerances, tractive performance, and operational lifespan in accordance with international quality standards (ISO 9001).
Traction Motors & Heavy Electrical Machines
Complete motor rewinding and VPI insulation treatment for DC traction motors (TL-2K1 and derivatives), dynamic rotor balancing, commutator resurfacing, and full-power load bench testing.
Wheelsets, Bogies & Running Gear
Ultrasonic axle defectoscopy, tire replacement and reprofiling, complete overhaul of roller bearing axle boxes, and hydraulic press-fitting under certified dimensional tolerances.
High-Voltage Switchgear & Apparatus
Comprehensive teardown, refurbishment, and calibration of high-speed circuit breakers (BV), electropneumatic reversers, line contactors, and protection relays for 3 kV DC circuits.
Auxiliary Systems & Static Converters
Overhaul of compressor and traction blower aggregates, modernization of pneumatic dual-circuit braking apparatus, and replacement of rotary converters with solid-state static converters.
Locomotive Life Extension (+15 to 17 Years)
Our certified life-extension overhaul program prolongs the active operating cycle of mainline electric locomotive fleets by 15 to 17 years at a fraction of the capital expenditure of new rolling stock procurement. The program reinforces structural underframes, repairs body fatigue zones, replaces low- and high-voltage cabling routes, and overhauls mechanical bogie suspensions.
Driver Cab Ergonomics, Microprocessor Controls & Operator Safety
Outdated analog gauge clusters are replaced with an advanced modular operator control deck:
- Integrated microprocessor control with digital multifunctional diagnostic screens;
- Ergonomically engineered consoles for the driver and assistant engineer;
- Dual-zone climate control, heavy-duty thermal insulation, and active cab acoustic dampening;
- High-impact laminated heated ballistic-grade safety windshields providing complete operator protection.
