“ Hello ， Hello ，I am Wu Shandong, the service engineer of Sany.。”Just picked up the phone.，The opposite side is a meal output.，Be in a hurry to tell the problem of your equipment。 Original ，Linyi Zhenqiang Hoisting Co., Ltd. received a job to replace chemical equipment.，Requires 220 ton crane for immediate departure.，But before departure.，The operator found that there was some oil leakage in the big arm.。

Hear this，He reassured his clients.，Turn around while looking for the nearest intersection.：“Don't worry，I'll be there in the shortest possible time.，It won't delay the construction.，Please rest assured。”

23 minutes later，Wu Shandong arrived at the parking lot of Linyi Zhenqiang Hoisting Co., Ltd.。He was dressed in thin overalls.，Walk quickly to the equipment with a toolbox.，He kept doing the preparatory work before drilling the big arm step by step.。The wind of minus 10 degrees made Wu Shandong's body a little stiff.，But he did not slow down his work.。

Ready to go，Wu Shandong picked up the wrench and slipped into his big arm.，Begin troubleshooting。He introduced：“According to the previous conversation with the operator，I'm pretty sureThe oil leakage of the big arm is due to the long-term use of the equipment.，The back and forth vibration of the big arm loosens the valve of the oil circuit.，It is a general fault。Let me go in and have a look.，Sure enough。”

“The problem was solved when I tightened the valve with a wrench.，After screwing it, he repeatedly checked other places.，It came out when it was sure there was no oil leakage.，It only took more than 10 minutes.。It sounds as if the glitch is easy to fix.，But because of the drill boom,，Plus the inside is small and dull.，If there is no professional training，It may take a lot of time to find the leaking valve accurately.。”

After the equipment returns to normal，Wu Shandong came out of his big arm.，The customer was found waiting by the equipment with his jacket in his arms.。

Wang Ziqiang of Linyi Zhenqiang Hoisting Co., Ltd.：“The temperature was very low that day.，Plus the wind，The big arms are all ice hands.，But he tried to save time.，He came on the stage in his thin clothes.。I saw him shaking a little.，I just want him to go inside and get warm.，ButHe insisted on finishing the work first.，Until the fault is completely eliminated.，He just put on his jacket.。”

For Wu Shandong's performance.，Wang Ziqiang was very moved，Take the initiative to send a circle of friends to praise the Sany service.。He wrote：“To buy a car is to buy service.！Thumbs up for your warm service.。”
