Jin Yang, the service engineer, is currently responsible for the after-sales service of Sany crawler cranes in Huainan area.，He is“After 00”，Young but meticulous in work。

September 6 at 11 p.m.，Jin Yang was getting ready to finish his work.，Received a service consulting order from Tongling，The customer reported that the 30-ton crawler telescopic boom equipment driven by the customer was under construction for a long time.，The luffing cylinder supporting the boom has the phenomena of unloading and automatic retraction.。Due to hoisting safety，So call for help to see if it can be solved through remote guidance.。

By asking，Jin Yang learned，The equipment is used to hoist the steel structure at a local construction site.，The construction period is very tight。In order not to delay the normal operation of the equipment the next day，He decided to go to the scene.。

In order to solve the problem as quickly as possible after arriving.，Before departure，Jin Yang has planned the travel route and the work to be done on the spot in advance.，For example, where and parts need to be disassembled for inspection，How to solve the problem after inspection, etc.。

More than 3 A. M. on September 7th.，Jin Yang set out from Hefei.，Go to Tongling City，A journey of nearly 200 kilometers，He draped the stars against the wind.，Can't see a trace of exhaustion.。Arrive at 5:30，He followed his original plan.，Begin troubleshooting methodically。

Jin Yang said：“It's still cool in the morning.，Blowing the slow morning wind，Lying between the upper arm and the track, you can't feel the heat.，But when the sun comes out,，The surface temperature rises slowly.，Hot and dry wind and ground dew evaporation，You can't help sweating.，At that time, I was holding the dismantled parts in my hand.，It's all oil，I can't wipe the sweat off my face.，But none of this is anything.。”

After two hours of inspection and maintenance,，Facing the sun at eight in the morning.，The big arm of the equipment is slowly raised.。The fault is seen to clear，The customer kept thanking him：“The equipment is in a hurry to start.，I didn't know what to do.，But I was relieved when you came.。”

Do the service，Although I have to go out early and come back late，Sometimes I have to face the sun and rain.，But Jin Yang never complained.，Instead, I like this job very much.。He said：“See the device back to normal，See the customer is no longer impatient，This made me find my own value.。”
