As a resident service personnel, he has been sticking to the Yunnan-Guizhou Plateau for four years, providing comprehensive and thoughtful equipment maintenance services for Sany Heavy Equipment's customers.

On May 15, in a coal mine in Zhaotong City, Yunnan Province, Cao Jibin was carrying out equipment inspection work as usual - the hard rock that was working undergroundTBMsEBZ260H is the equipment purchased by the mine in 2023, and it has been in operation for 1,000 hours so far, and has successfully advanced 600 meters, especially in the case of rock hardness F7, which is remarkable.

During the equipment inspection, Cao Jibin noticed that there was an oil leak at the front end of the cutting arm of the roadheader. After discovering the problem, Cao Jibin began to carefully investigate and analyze the failure - worried that the lack of oil would cause greater risks, and also considering the subsequent use of the equipment, he immediately asked the mine to shut down the shutdown and stop production, and quickly ascended the shaft to formulate a repair plan.

After ascending the well, Cao Jibin checked the inventory of the spare parts warehouse, urgently applied for the appropriate seals, and turned his head to go down the well immediately without taking a break, organized the replacement of accessories and carefully checked. It took only 4 hours from the discovery of the fault to the completion of the problem, and the entire process was orderly, which gave the customer peace of mind.

After understanding, the mine's basic maintenance ability is weak, Yunnan regional service engineer Cao Jibin actively carried out equipment inspection, timely investigated the risk failure, and quickly and efficiently solved the problem, prevented the cutting arm bearing, spindle damage and other major failures that may be caused by lack of oil in the later stage, shortened the maintenance cycle of the equipment, ensured the production progress of the mine, and escorted the safe and efficient production of customers with practical actions.
