“One, two and three, hard!”, as the deputy chief of the Wuxi Railway’s depot maintenance department happily spoke, the axlebox of the first round of the Shaoshan 6B 1108 electric locomotive steadily meshed. "Hold up the bolts!" When he was happily using his legs to press on the axle box, he only heard a crash and his safety shoes were scrapped again.

Locomotive information is the most effective way to understand the locomotive's dynamic operation information and master the locomotive quality. Welcome, ask, examine, close, and clean are the main working procedures for the refitting of locomotives. Only the “examination” aspect of this activity should at least be carefully circumscribed around the locomotive. One day, when he was 1.8 meters tall, he would walk more than 10 kilometers more than anyone else. It wouldn't be surprising if he took a few more pairs of shoes.

On the job site, you can often hear that you are happy to remind you that you must hang your seatbelt on your roof, hold it firmly, and pay attention to slipping and falling. You must carefully inspect every part of the vehicle to check for looseness. In the car, carefully check each small screw. After the operation was completed, he carefully checked each vehicle again and closed the locomotive battery to prevent the locomotive from malfunctioning due to the loss of power caused by the long-term load operation of the locomotive. Every day, he is always the last one to return to the break room.

On the morning of November 12th, the 10th Lushan 6B type 1122 and 6025 electric locomotives during the trimming operation, at the moment of the operator hanging the wiring, Happiness found an important safety hazard - the grounding wire and the grounding rod hook connection disconnect. It is not easy to find such a problem if it is not careful.

Labor insurance shoes will be issued in accordance with the regulations for one and a half years. The workshop will be granted five batches of happiness each year. In the activity of the “Hundreds of High-quality Locomotive Overhaul Competition” carried out by the Wuhan Railway Bureau, Happiness was the leader in the maintenance system. As of November, he had created 4,775 sets of excellent results and became a truly “top 100 champion”.
