Sany Heavy Industry Co., Ltd.: The original aspiration remains unchanged, and the dedicated service is consistent!

September in early autumn，Northeast China has been hit by a cold wave.，Many projects want to catch up with the progress before the winter break.。Jilin Zhongqing Group's high-speed project around the city is in full swing.，People rest and equipment does not stop.，Go all out to complete the construction schedule。Sany Second-hand Purchased by Jilin East Coal Foundation Co., Ltd., the ConTractor of the ProjectSRThe 280 drilling rig is also under construction.，Because of continuous high-intensity work，The device has malfunctioned。

September 24 at 5 a.m.，Hu Dongdong, the service engineer, is still sleeping.，The prompt tone of the mobile phone Yiweixun rings.，There is a repair order to be processed.。After checking, it is based on East Coal.SR280 is faulty，After communicating with the customer through the virtual number, he learned that the mast deviated rapidly as soon as the equipment turned.，Mast failures can be large or small，The operator dare not operate again.。The customer is very anxious，The engineer immediately went to the warehouse and rushed to the customer's site with the accessories.。After arriving at the construction site，The engineer underwent an emergency investigation.，Determine that the problem is a cylinder counterbalance valve problem，After the new balance valve is replaced, the customer operator repeatedly tests the machine to confirm that the fault is eliminated.。From Report for Repair to Equipment Recovery，It only took three hours.。

October seventeenth，The engineer receives the repair order from the customer again.，This time, the equipment had a failure of bottoming function.。At present, the hole depth of the bid section is 38 meters.，And that formation is complex，Due to bottoming function failure，Rope disorder of main winch will occur.。First, it will increase the wear and tear of the wire rope.，Second, rope arrangement also delays the construction progress.。Engineers rushed to the scene after learning about the situation.，After maintenance, it is confirmed that the tension sensor harness has an open circuit.，The tension of the main winch recovers after the open circuit harness is rewired and calibrated，The bottoming function is valid，Maintenance only 1 hour and 20 minutes。

The customer came back from the project department and saw the engineer asking.：“When will the fault be fixed?，How long is it expected to take?？”When the engineer informs the customer that the equipment has been repaired and is ready for construction，The customer was overjoyed，Sincerely sighed.：“I didn't expect you to come so fast.，Maintenance speed is also fast.，I thought I bought a second mobile phone and it was old.，After-sales service will not be so timely.，It's beyond my expectation.。The first time fast may be a coincidence.，The second time fast is definitely the attitude.，Although I bought the old equipment.，But your service is really not compromised.。”
