The roles assumed by the two Kobelco’s cranes

Two Kobelco’s crawler cranes, the CK2750G-2 and CK1600G, are operated at the riverside construction site. There are a total of four cranes – two each at the north and south side of the bridge. For this interview, we covered the north side of the bridge. In what way does A.H. BECK FOUNDATION use these two cranes?

“The CK1600G mounts the Kelly bars for ground excavation and the drill shafts, and operates the originally developed power system. With this, we can scoop out mud and drill down to the bottom. The other CK2750G-2 is used to transport rebar cages that are buried underground, and hoses for the sludge system.”

We began our coverage at noon.
A large hole was excavated, and the rebar cages were slowly and carefully buried underground. By the time the rebar cages were buried, the sun was completely set.

“We are drilling to embed rebar cages 270 feet deep into a 96-inch diameter hole. We drill slowly and steadily until we reach the bottom. The drilling of the hole must be perpendicular to the ground and requires perfection in many ways.”

Once the hole was completed without any problems, the next process was the installation of the rebar cage.
After installing the rebar cage, the hole was filled with concrete.

“The work of the Kobelco’s cranes on this site has been second to none. You could say that they are the driving force for a successful construction. They can be operated every day without any problems, and we expect the completion of the work to be a little ahead of schedule. The cranes are very tough and I can’t think of a better partner.”

Mr. David Stroup smiling at the performance of the Kobelco’s cranes.
In the unlikely event that the cranes are forced to stop operation in a major project like this, it would be disastrous. We can see the smile on his face because as of now, they have operated without any problems, but we asked him about the preparations for an unexpected emergency situation.

“If a problem occurs, our employees have received mechanic training in order to resolve and repair it within several hours. Of course, these types of problems should never occur in the first place.”
