Nigeria is the largest oil producer and exporter in Africa. The Dangote oil refining and petrochemical project in Lagos, Nigeria, is the largest oil refining project in the world.

Here, nearly 100 XCMG excavators are working together to push forward the project construction. At the same time, XCMG workers are guarding the construction site with excellent technology and high-quality service. They have a common name - XCMG overseas service craftsman.

Leaving families and crossing the sea, XCMG's overseas service team came to Africa. They had to face the intense heat in the dry season and the hot tides in the rainy season, the rampant mosquitoes and frequent diseases in Africa. They had many stories to share.

One day, the project party was going to disassemble a XE215C excavator that had worked for more than 12000 hours to recycle the parts. XCMG worker Jiangping YIN learned that the equipment was still fixable and didn’t have to be broke into parts.  After inspection, he found the connection between the slewing motor and the slewing platform was broken and separated. He volunteered to repair it. YIN borrowed tools such as grinding machines and welding guns from the repair shop, patiently polished the broken and stuck bolts, and then selected high-strength welding rods to connect the rotary motor and the turntable bit by bit. After several days, the XE215C raised its arms again and went back to construction site.

XCMG worker Wei GAO suffers from severe shingles when he arrived, the burning pain is unbearable. In the evening, GAO was lying on the bed when he was told a XE235C excavator was driven into a swamp and could not get out. The experienced old divers were all off duty, the project management personnel tried hard, but no progress had been made. There was a rainstorm in the sky. If the excavator was not ‘rescued’ in time, serious losses would be cost. GAO rushed to the scene with his weak body under the storm. He first appeased the embarrassed excavator driver, then coordinated to tow the vehicle. After an hour of hard work in the swamp, the excavator was finally rescued.

The technic trainer Tao DING always attached great importance to the improvement of the skill level of the service team in Dangote project. He believed that theory should be combined with practice, and it was better to put service personnel in the work scene, so as to better improve their skills. At noon, a XE215C excavator gave an alarm of high hydraulic oil temperature, DING led the service team to the scene quickly. They checked the scalding oil tank, finding that the filter and radiator were not blocked. Under DING’s guidance, local colleagues soon realized that the distribution of hydraulic oil to the radiator and hydraulic oil tank was the problem. DING disassembled the oil return check valve, adjusted the pressure, completed the installation and commissioning, and the fault was removed. The project party were observing and learning beside DING.
