Of the 310 million service workers,，Tower crane service engineers are somewhat special.。It is not only because they are overhauled at an altitude of 100 meters all the year round.，And becauseTower crane after-sales service has an unwritten rule：The total after-sales time within one month shall not exceed 72 hours.。The reason is that the after-sales standards of tower crane equipment are extremely strict.，Once the fault is not solved in time，It will lead to the suspension of the construction of the whole project under construction.。

Wu Qingbin, 42, is a tower crane in the Sany Fujian region.“Security expert”。It has been 12 years since 2011.。For“High-altitude consultation”，Wu Qingbin said he was used to it：“This is a common practice.，I have participated in the internal inspection of the Third Bureau of China Construction at the end of the year.，The height of the overhaul is about 260 meters.，It is now a landmark building in Jimei New Town, Xiamen.。”

▲ Wu Qingbin has participated in the first high-rise project outside Xiamen Island.，A tower crane on a project in Yongan, Sanming, Fujian tripped.，Wu Qingbin immediately rushed to the scene for troubleshooting.。He climbed up the tower crane.，Pass the tests，Finally, it was confirmed that the motor was short-circuited.，Needs to be replaced。It may take several days to deliver the goods from the warehouse.，But the construction site can't afford to wait.，Customers can't afford to wait.。

  

Just when everyone was burning with anxiety.，Wu Qingbin thought that there was a spare motor in the customer base 300 kilometers away.，He set off at once，Drive 4 hours to the base to get the motor back for installation。Back to the construction site again.，It is already more than 7 o'clock in the evening.。In order not to affect the start of work the next day，He decided to install it overnight.。

Replacing the motor itself is not difficult.，But the tower stayed aloft.，Plus the visibility is very low at night.，This undoubtedly increases the difficulty of maintenance.。Wu Qingbin went to the tower again.，Climbed the 45-meter-high standard section.。He asked the operator to help with the flashlight.，Two people cooperate with each other.，Move the motor weighing up to 200 kg to the designated position bit by bit for installation。Through the wiring-Test the machine-Several steps of line adjustment，The installation is complete，After confirming that the equipment was working properly, he went down the tower.。In a twinkling，It's already past ten o'clock in the evening.。

  

Except for the directional call，Wu Qingbin will alsoTake the initiative to patrol the equipment，And give regular feedback to customers.Equipment condition，Give customers more peace of mind。

Wu Qingbin said：“In fact, I have also felt tired.，But think of the whole site may be forced to stop work because of equipment failure.，I think we must solve the problem as soon as possible.，I dare not stop.，To minimize the loss of customers！”
