Shaoshan 4 improved electric locomotive, code SS4G. On the basis of SS4, SS5 and SS6 electric locomotives, some advanced technologies of 8K locomotives are absorbed. The locomotive consists of two independent and interrelated cars, each of which is a complete system. The locomotive is equipped with anti-skid turning device. Each car has two B0-B0 bogies. Push-pull traction is adopted. The fixed wheelbase is short. The motor suspension is axle-holding semi-suspension. The first one is spiral circular spring, and the second one is rubber laminated spring. The traction force is transmitted directly from the inclined bar at the lower part of the traction beam to the car body. The air brake adopts DK-1 brake. The locomotive power lasts 6400 kw, the maximum speed is 100 km/h, the length is 2 x 15200 mm, the axle type is 2 (B0-B0), and the current system is single-phase power frequency AC. The main purpose of this paper is to understand the treatment and analysis of the common faults of SS4G electric loc
