Air Docking 66 m Tower Arm, Sanyi Red Challenge "Impossible"!

Recently，Yang Haibing, Chairman of Jiangsu Bailiwei Construction Machinery Leasing Co., Ltd.Encountered a difficult matter.：Changzhou Kaixiang Medical Stainless Steel Co., Ltd. will install steel beams on the roof of the factory building.，But the friends who had been to the scene to investigate all beat a retreat.，Think“The load cannot be lifted normally”。

In order to understand the specific situation，Yang Haibing also went to the work site.。According to the actual situation,，The steel beam weighing 23 tons first has to cross the first 28 meters from the side of the road.、A house 25 metres high，After reaching the roof of the second house, the installation is carried out.。

Yang Haibing thinks，650-ton all-terrain crane can be used，However, it is impossible to complete the lifting on site only by the main boom.，It can only be completed under the conditions of tower and main boom super-lifting.。There are houses all around.，The space is small，The distance left is only enough to stop the main engine.，The 66-meter tower arm will be installed here.，It's completely impossible。

It takes nearly ten days to install the steel beam.，At that time, the construction period was already very tight.。So，Yang Haibing did not dare to promise rashly.。But at the same time，He has actively contacted Jin Kaihua, a service technician，Seek solutions for tower arm installation。After two hours of discussion,，He thought：“If the ground can not be installed normally，Then dock the tower arm in the air.。”

Yang Haibing said：“Others said that my idea was too bold.，Air docking is too difficult.，Almost impossible to complete.，But I think.，Clients come to me out of trust.，I will try my best to do it anyway.。”

After the operation plan is finalized，This one“Mission Impossible”It's officially launched，Jin Kaihua led two other engineers, Liu Zhuo.、Join in with Liao Shuilong“Battle”，Three auxiliary cranes were also dispatched.。The first auxiliary crane lifts the tower arm to be installed in the air.；The second auxiliary crane is used to fix the tower arm.，Maintain stability and prevent jitter；The third one is used to ensure the safety of the installation personnel.。Careful division of labor among project teams，Keep an eye on every link.。

From Assembly to Commissioning，After a day and a half.，Finally, 650 tons successfully completed the 66-meter tower arm grafting.。The afternoon of the day the equipment was in place，The red big arm steadily lifted the first piece of steel beam.，It drew a lot of applause from the scene.。

Yang Haibing said：“Judging from this assembly incident,，Neither Sany's engineers nor Sany's cranes let me down.，This proves that my choice is very right.。”

At the same time，The construction manager of Changzhou Kaixiang Medical Stainless Steel Co., Ltd.：“In fact, I didn't expect to use Sany's car at first.，But they came up with a solution and implemented it in such a short time.，Very efficient，I will look for Bailiwei when I have a job in the future.，Still use Trinity's car.！”
