Lately，Zhengzhou Shujie Handling Service Co., Ltd.Zhao Kui, the boss, encountered a problem.。

Zhao Kui said：“We dispatched three truck cranes.，In the project of PICC Building in Zhengdong New Area, the reinforcement cage was lowered with the help of the rotary drilling rig.。Early stage，In order to get the truck crane into the field，Excavators were used to repair the road.，Laying of steel sleepers，It costs a lot of manpower and time.。”

“After the equipment finally entered the site,，Rotary drilling can form many holes in one day.，The truck-mounted cranes had to be shifted one by one.、Hit the legs。With the gradual acceleration of the project process,，Construction nodes are getting closer and closer.，According to the current progress of this operation,，I'm afraid it's hard to finish the task.。”

When Zhao Kui was very distressed.，He saw an article in the circle of friends.。It says in the article that，A construction site in Shenzhen is using a telescopic crawler crane to cooperate with a rotary drill.，The efficiency improvement is very significant.。Therefore，Zhao Kui took the initiative to learn about it.，With a try mentality，He purchased one.STB300T5-6，And jump right into the project.。

STB300T5-6 After admission，Facing harsh construction environment，The advantages are obvious。ItStandard four-wheel belt，Tilt 4°It can still be hoisted，No need to spend energy leveling the road.。There is no pressure to walk with a load on the muddy road.，After completion of drilling with rotary drill，It then lifts the reinforcement cage to the opening，And put it into the hole to finish the cage.，A set of movements at one go，Construction efficiency has been greatly improved。

  

Zhao Kui said：“After this telescopic arm enters the site,，I pulled two truck cranes back.，Only one truck crane was left on the site to cooperate with the operation.。Although the equipment has been reduced.，But there is no need to repair the road and no need to wait for the truck to lift the outriggers.，Therefore, the construction efficiency is not reduced.，And improved by at least half.。One telescopic arm can cooperate with at least two rotary excavators at the same time.，The construction side recognized it very much。The two truck-mounted cranes I removed can also take other jobs.，Kill two birds with one stone，The earnings also doubled directly.。”

  

At present，Most of the foundation construction sites in Zhengzhou are still dominated by traditional construction methods.，Transfer the reinforcement cage with one or more excavators，Then a truck crane is used to cooperate with the rotary drill to hoist the hole.。However, the traditional construction method has obvious disadvantages.，If it rains,，The truck crane will be more difficult to move.。So，It is imperative to change the method。

  

China Construction Seventh Engineering Bureau Co., Ltd. Haoding Zhengdong New District People's Insurance Building project security inspector Wang Ning said.：“In Zhengzhou，I've only heard of it before, but I haven't really seen it.，Know that its construction efficiency can，But I didn't expect that one of them could be worth two truck cranes.。Efficiency improved so much，Our construction period is also guaranteed.，After the work of foundation construction, I must be the first to think of Zhengzhou Shujie.。”
