Video shooting and production: Wang Xiaoqing, Bao Na is good
Xining, CCTV News on May 1 (Reporter Wang Xiaoqing, Intern Bao Nahao) "Ding Ding Dong Dong ~ Bang Bang Chang Chang" Li Faye held a small hammer and kept tapping around the body and wheels of the truck, with sharp and rhythmic movements, like a sonata performed on the railroad tracks.
The hammer is an important "weapon" for the inspector. This seemingly simple tool carries the dedication and responsibility of railway people to safety.

"Don't look at it as a small hammer, we just started to check the status of the truck, we just rely on the hammer and the ear. China Railway Qinghai-Tibet Group Co., Ltd. Xining East Depot Freight Car Inspector Chief Technician Li Faye said.
By striking the parts of the vehicle with the inspection hammer and listening to the sounds, the inspectors are able to accurately determine the condition of the vehicle. This method may seem "original", but it requires the accumulated experience and rigorous insight of the inspectors.

At the beginning of Li Faye's career, the use and maintenance of trucks and vehicles mainly relied on manual operation, using basic tools such as oil picks, sledgehammers, flat shovels, etc., mainly using hand touch, eyes to see, ears to listen and other ways to judge and deal with equipment failures, the efficiency and accuracy of vehicle inspection are greatly limited by personal experience and skills, and labor intensity.

In recent years, with the vigorous development of railway science and technology, the way of freight car maintenance has begun to change to mechanization and automation. In particular, the intelligent sorting system for bearing removal, the robot automatic painting device, the brake beam grabbing manipulator, and the painting and drying line of the hook retardation device have been put into use, which not only optimizes the work process, but also improves the maintenance accuracy and operation quality.
Li Faye told reporters that with the continuous development and progress of railway construction, the mechanization and intelligence level of railway maintenance work has been continuously improved, and there are many "good helpers" in maintenance work, which can make train maintenance operations more convenient, efficient and accurate. However, holding a car inspection hammer in hand and knocking on it to inquire about the status of the train is still a long-term professional habit of the car inspectors.
