Among the existing rotary drilling drills in China, there are many manufacturers, but the most famous ones are Sany Heavy Industry and XCMG Group. Pen, fun, pavilion www. biquge。 info

Among them, the rotary drilling drill produced by Sany Heavy Industry is the most used in the engineering unit.

Many large state-owned enterprises, in order to facilitate construction, often import this kind of construction machinery from Germany.

Shucheng has to admit that the German construction machinery is indeed awesome, but the price is also very expensive.

The most famous shield machine is only produced in China for more than 50 million, but Germany imports more than 200 million, which is more than four times that of domestic production.

However, the drill bit imported from Germany, one can be used for half a year or even a year, and the domestic shield drill bit can be used for two months at most, which is very awesome, and the drill bit is particularly diligent.

From Faku County to Shenyang, it took about two hours, mainly the first time to drive, not very familiar, into Shenyang City, obviously feel the difference between the county and the provincial capital, the architecture of Shenyang City, than the small county town of Faku is much better.

After arriving in Shenyang, Shu Cheng made a phone call directly, and then navigated to the address given by the other party.

Soon, he came to the branch of Sany Heavy Industry in Shenyang.

When Shu Cheng came to the door of Sany Branch, there were already people waiting at the door, let the doorman open the opening bar to make way, and the domineering off-road vehicle directly entered the courtyard, and after the car stopped, Shu Cheng and others got off directly.

"Manager Ma?" After Shu Cheng got out of the car, he said to the man in a suit who came from the door.

"Hello Boss Shu, I'm Ma Rulong, the business manager here!" Ma Rulong smiled.

Shu Cheng had been in contact with him before, saying that he wanted to buy a rotary drilling drill, but Shu Cheng did not mention how many.

In fact, Sany Heavy Industry's friends, Shucheng also knows, but there are no acquaintances in the northeast area, most of them are concentrated in the southwest region, and they are not familiar.

"Manager Ma, excuse me, this is the secretary of our headquarters, and I have already commanded Yu and Wang!" Shu Cheng introduced.

Ma Rulong greeted the three of them, and then said, "Four leaders, please go to the office and sit down!" ”

Soon, the five of them went up to the second floor of a nearby office building and entered a reception room.

When he came in, there were already female employees of Sany Heavy Industry to help make tea, and it seemed that Ma Rulong really looked like a leader.

"Bosses, please have tea." After Ma Rulong sat down, he said to Shu Cheng and the others: "Boss Shu, may I ask how many rotary drilling drills are needed for your project?" ”

"Manager Ma, can you let us see the model of the rotary drilling drill first, we want to see what kind of rotary drilling drill model is more suitable according to the geological conditions of our project, as for the quantity, we have to determine the model before we can determine how many units are needed!" Shucheng Road.

For rotary drilling, Shu Cheng did check on the Internet, in fact, the easiest way, don't look at how much power, directly let the other party tell you, how many meters this rotary drilling drill can drill.

For example, how much does it cost to drill at a maximum depth of 40 meters, and how much does it cost to drill 60 meters and 80 meters.

For the corresponding number of meters, the rotary drilling drill is also equipped with how much power and how much torque, which is clearly written.

The power of the rotary drilling drill is generally 125-450KW, and the power output torque is 120-400KN・m, like the ordinary soil pile foundation, the torque of about 200 can be satisfied.

However, there is a part of the rock formation in the lower part of the pile foundation on the Changqi Railway, and the torque needs to be at least 200 KN・m, otherwise it will not be possible to construct at all.

"That's easy to say, wait a minute!" Manager Ma got up with a smile and said.

After a while, Ma Rulong brought four thick bound books and gave one each.

After Shu Cheng and the others took it and opened it, there were all kinds of rotary drilling drills, of different sizes, all of which were relatively complete, but they were not marked with any amount of money.

"Manager Ma, are these rotary drilling drills in stock in the branch here in Shenyang?" Shu Cheng asked as he looked through it.

Because he needs a lot at one time, he is afraid that when the time comes, Ma Rulong will not be able to provide it for a while.

"There are some in the backyard of the office area, and each kind of machinery is one or two, if Boss Shu needs it, we have a storage warehouse in the suburbs, and we can directly transfer it from that storage warehouse when the time comes." Ma Rulong Road.

Large equipment like rotary drills, all to this branch, is not realistic, how to transport in, are a problem, these for the visit of the machinery, or very early, dismantled and transported in assembly.

Within the urban area, large machinery and equipment are often reversed, and it is no wonder that the traffic police do not punish you to death.

Therefore, Sany Heavy Industry has a warehouse in the suburbs, most of the machinery, are stored there, after the customer selects the model, you can go to see the goods first, after reading, arranged by Sany Heavy Industry Branch to send to the designated place.

"Are there more rotary drills for each type over there?" Shu Cheng asked again.

"Looking at that type, there will not be a lot of general inventory that sells more hot." Ma Rulong Road.

Shu Cheng nodded slightly, and after reading it, Shu Cheng said, "Commander Yu, what model do you think is good to buy?" ”

Yu Chunan groaned slightly, he used to be a grassroots worker, with rich construction experience, and thought about it: "I think since I bought it, I will buy a torque of more than 200KN・m, after all, the length of our pile foundation is about 50 meters, plus the empty drill, I can see that it can reach 55 meters at most, and there are several meters of rock formation below, and the power is larger, so that the construction progress is also fast!" ”

"Yes, I think the torque of 220KN・m is about the same, no matter how big it is, there is no need for this!" Wang Qingmei also said at this time.

"In fact, according to the drawings, the pile base of the first division is obviously not as hard as the second and third parts, my suggestion is to buy one with 200 KN・m torque, buy one with 220 KN・m torque, and finally buy another one with 250 KN・m torque." Shucheng Road.

The reason for the purchase of the 250KN・m rotary drilling drill is to consider some special locations, and at critical moments, it may be possible to rush the construction period.

When Ma Rulong heard the chat between the three of them, he couldn't help but look shocked for a while, and secretly thought: Good girl, the lowest price of this 200KN・m torque is also 2 million, and the configuration is a little higher, which is directly 2.5 million to 3 million.

For the rotary drilling drill with a torque of 220 KN・m, the one with a higher configuration jumped directly to 3 million!

The last type of rotary drilling drill with 250 KN・m torque, the highest configuration, up to 5 million units, if the other party buys three units at a time, the configuration is medium, the total amount is almost 10 million!

With sales of 10 million, Ma Rulong's mention is a lot of money, and Ma Rulong feels that he has to take him down no matter what.

When Shu Cheng and several people discussed, Ma Rulong did not interject, and finally after the three of them finished discussing, Shu Cheng asked: "Manager Ma, a rotary drilling drill with 200KN・m torque, medium configuration, how much is one!" ”

For the general soil layer, with 200KN・m torque rotary drilling drill, there is no problem at all, the reason why Shucheng bought a better rotary drilling drill, mainly considering that these things, can not be one-time, can also be used in the future, in this case, when buying, it is better to buy better, do not use after the discovery is not suitable, and then change it will be troublesome.

"In a medium configuration, 2.3 million units!" Ma Rulong Road.

"Manager Ma, let's tell the truth, the 200-torque rotary drilling drill, in my opinion, the highest configuration, is 2.5 million, for the general configuration, 2 million has reached the sky." Shu Cheng smiled slightly. (To be continued.) )
