Machines don't express their problems like people do.，In the event of an occasional failure，Often, the engineer has just arrived at the construction site.，The glitch is gone.，Or when it returns to normal.，Just left the construction site，The fault occurs again，And when he returned to the site again,，The fault did not appear for a long time.，At this time, engineers are required not only to have exquisite technology.，And rich experience.，More importantly, we should have a heart that is brave and uncertain to the end.。

On October 21, I received a call from Li Weiming, a customer in Wuzhou.，Loss of rig inclination data，Unable to ensure the verticality of the drill hole，Engineer Shen Yong rushed to the scene immediately.，After the short circuit circuit of the sensor is repaired and wrapped，Fault removed。

On October 26, the customer reported that the drilling rig speed dropped suddenly.，Turn off the electricity and have a rest.，The fault is automatically cleared，When Li Zheng learned about it, he thought it was necessary to check the equipment.，He cancelled his holiday at once.，Directly turn around and get off the highway and arrive at the customer's construction site within 20 minutes，Li Zheng didn't eat，Start troubleshooting now，Until one o'clock in the afternoon，Leave the construction site after the fault is removed.。

  

On November 9, the customer fed back the main winch upper limit alarm.，Screen operation does not work，Wang Hai, an engineer, drove more than 150 cars to the site.，There's nothing wrong with the rig again.，Wang Hai is hereCRMAfter the query，It is not easy to realize this fault sensitively.，If we go now, we may cause the rig to stop again.。

Wang Hai takes advantage of the client's lunch break.、Dinner shift time，Check whether the line of the drilling rig is flooded.、Loosening and other issues have been comprehensively arranged.，Still no anomalies found.。More than 9 P. m.，The drilling rig has been working normally for more than 20 hours before leaving.。

  

It was thought that the mission was successfully completed.，The SANY equipment in another work area of the construction project also needs to be overhauled.，The two men hurried to deal with it.。It was found that the rotary reducer assembly and the main winch brake pad needed to be replaced at the scene.，It can only be transported to Tibet by special vehicles from Chengdu in an emergency.。So the two men welded the drill pipe on one side.，While waiting for the arrival of the reducer and brake pads.。

  

Touch screen failure occurred again on the drilling rig on November 10.、Drop speed、The inclination is not accurate。However, due to the tight schedule,，Frequent failures，The customer is extremely anxious，The branch company gathered Zhang Fangqing.、Shen Yong、Wang Hai and three engineers went to the construction site together.，Each person took turns to squat on the drilling rig for one hour.，Preempt the minutes of failure，Arrange the line。

Monitored，It is preliminarily judged that the electronic components inside the display are automatically protected after overheating.，Performance failure。At this time, the pile hole under construction by the customer is still 10 meters away.，If you wait for the company to send the monitor.，The pile will collapse.，It is necessary to pile again after backfilling the low-grade concrete.，Not only delayed the construction period for 3 days，It will also bring losses to customers.，The engineer immediately applied to remove a set of monitors and controllers from the rental machine.，Temporary use for customer construction。   

  

Use the rental machine on the second day during construction of the display and controller，There will also be occasional speed drop failures.，With experience as an engineer，It is believed that the rig is not only damaged by the display，There are also problems with the circuit.。The engineer placed the bottom cover plate of the rig、Mast、Cab、All the lines around the electric control cabinet were turned over.，Finally, it was found that the pin of the tilt sensor was loose.，Problem caused by oxidation at the root of the mast harness connector。When the engineer finds out, he will deal with the fault immediately.，Subsequently, the insulation upgrade was carried out on the problem points of the vehicle wiring harness.，It was not until 9 P. M. that the problem was completely solved.，Three days of squatting were not in vain.，Half of the pile holes constructed by the customer were successfully completed.。

  

When the engineer left，The customer said“Thanks to the timely help of your Trinity service, I was saved from loss.，This rig，I used it for 17000 hours in four and a half years.，There are basically no major failures.，The product quality is excellent，Sany's after-sales service has inherited the hardships of Hunan people.、Overbearing、The spirit of patience，Attaboy!”But for engineers,，This is very common.，Because，“Whatever it takes，Make the service to the utmost.”It is the motto of all Trinity service people.。
