"Why don't other manufacturers seize business opportunities, research and development and production?" After seeing Zhao Siyan ask this question, Zhao Guoyang smiled and said.

"Yes, I'm just wondering about this..." Zhao Siyan said with hope.

Zhao Guoyang sat upright and said calmly: "This issue depends on the composition of the drilling hoist."

"The drilling hoist is a type of mine lifting machinery. It is generally called a mine hoist internationally. It is mainly composed of working mechanisms, braking systems, mechanical transmission systems, lubrication systems, observation and operating systems, as well as dragging, control and safety protection systems."

"The structure is not complicated, but it is not difficult to put these together and make them into a product."

Looking at Zhao Siyan nodding slightly, Zhao Guoyang continued: "According to the information I know, there are only about six or seven domestic manufacturers that are capable of producing mine hoists."

"And, among these six or seven companies, there is only one enterprise, that is, the Southwest Mining Machinery Equipment Factory, whose mine hoist parts are nationally produced."

When Zhao Guoyang said this, Li Zhaohe, who was standing by, nodded repeatedly and echoed: "That's right, this Southwest Mining Machinery Equipment Factory is indeed the best in the domestic industry."

"I went to inspect once, and their size is much larger than our SMS company..."

Li Zhaohe said, sighing, "But a pity, their lives are not easy now."

"I heard that some time ago, their factory had just adjusted the production structure, and it seemed that several projects had been cut off, and the mine hoist project might be among them!"

"Well, it's not strange that the hardships of the Southwest Mining Machinery Equipment Factory are not a strange thing."

Zhao Guoyang said frankly, "Although they are large state-owned enterprises and their production technology capabilities are the best in China, compared with some foreign engineering machinery giants, the gap is still quite large at the moment."

"Before reform and opening up, perhaps the Southwest Mining Machinery Equipment Factory can rely on its own domestic advantages to get the wind and rain."

"But now the door to imported foreign equipment has gradually opened, and joint venture products have filled the entire mining equipment market."

"It is no surprise that the leadership of the Southwest Mining Machinery Equipment Factory failed to understand this clearly, change its thinking and expand its thinking in a timely manner, so it became difficult."

After looking at Zhao Siyan who was thinking, Zhao Guoyang waved his hand and smiled: "Hi, the topic is a bit far-reaching. The reason why I mentioned this Southwest Mining Machinery Equipment Factory is to explain the difficulty of manufacturing equipment such as mine hoists."

"Imagine that with the scientific research strength and production level of the Southwest Mining Machinery Equipment Factory, their national mine hoists are no longer sold and are almost cut off. This can more or less indicate the difficulty of manufacturing the mine hoists, right?"

Upon hearing this, Zhao Siyan nodded repeatedly and said, "Well, Mr. Zhao, I will understand after you say this."

"This mine hoist is indeed not that easy to manufacture. No wonder the world's market is so large, but there are only a few domestic mine hoist manufacturers..."

After muttering to himself a few words, Zhao Siyan asked again: "By the way, Mr. Zhao, it is difficult to manufacture a mine hoist now, and I already know that, but where is it difficult?"

"If our factory spends a lot of effort to build this product, can we overcome such difficulties and manufacture it, and its quality can also compete with other domestic joint venture mining equipment companies?"

After Zhao Siyan asked this question, Zhao Guoyang nodded with a smile and said, "Siyan, the ability to ask such a question proves that you have paid attention to the transformation of your role now, which is very good."

"You have been able to put yourself in the position of leader and think about problems from the perspective of a leader!"

"Yes, yes, it's so good. Although I feel very moved, I can't say anything. The Chairman's summary is really incisive!" Li Zhaohe responded very cooperatively.

When Zhao Guoyang and Li Zhaohe were praised at the same time, Zhao Siyan's face was covered with a light blush.

However, she was not the kind of pretentious girl. After she was slightly red, she continued to look at Zhao Guoyang with anticipation, and she was very impressed that she would not give up until she understood it.

Looking at the girl's eyes, Zhao Guoyang spread his hands and slowly said, "Siyan, your question is a bit wider. I'll analyze it for you one by one."

"First of all, there is one thing you need to figure out that a mine hoist is not just a lifting device, it also has other uses such as detection, transportation, and establishing internal and external contacts of wells."

"Of course, the most core part of this mining equipment is to improve the system. Let's start with this most critical core part!"

After Zhao Guoyang's story, not only Zhao Siyan, but also Li Zhaohe was attracted by great interest.

The two of them stared at Zhao Guoyang without a moment, wanting to hear his ideas and opinions below quickly.

Facing the eyes of the two, Zhao Guoyang raised four fingers and said: "From the narrow product set, the lifting system of the mine hoist is basically composed of four parts: the main part, the electronic control part, the electric motor and the gate control."

"One of the most important factors in our country is that the development of various parts of the lifting equipment is unbalanced."

Zhao Guoyang took a sip of water and moistened his throat and said, "First of all, let's talk about the host part being ready."

"At this stage, the gap between our domestic mainframe parts, namely the spindle, roll and wheel, is still very large in terms of product structure, technical level, safety and reliability of parts, and the international advanced level."

"Compared with similar foreign products, the configuration of our domestic mine hoists is too conservative, with heavy quality, and the optimization of structural details is not satisfactory."

"In addition, the difference in appearance of the product is also very obvious. I believe you should have some understanding of this!"

After hearing Zhao Guoyang's words, Li Zhaohe was deeply moved and said, "Yes, Chairman. The mine hoist I saw at the Southwest Mining Machinery Equipment Factory looked a bit dirt-like."

"Although the mining equipment is definitely covered in dust after use, there are still certain requirements for the beauty of the new products."

"But the appearance of their product is gray and not as good as it looks, so it is difficult for people to feel a desire to buy." Li Zhaohe shook his head and sighed.

Zhao Guoyang agreed: "Lao Li, your judgment is fine. Foreigners have higher requirements for product appearance abroad. This is also an important reason why the products of the Southwest Mining Machinery Equipment Factory are unable to go abroad for a long time..."

After talking about the host part, Zhao Guoyang continued to talk about other aspects.

"In addition to the mainframe, in terms of motors, the gap between our domestic products and international advanced levels is even more obvious."

"The single-machine power, appearance size, quality of domestic electric motors has a big gap with that of the same level of foreign products. The material application is conservative, there are huge gaps in heating problems, and cooling technology. Moreover, this gap cannot be greatly improved in a short period of time..."

Zhao Guoyang's words did not mean to belittle domestic products at all, and they were completely honest.

Due to the backwardness of the domestic materials industry, there is little room for material selection for domestic mine hoist motors.

The domestic quality of cast iron, silicon steel sheet, 45 or 40Cr round steel is not high.

Among organic materials, acetals, polyesters, polyurethanes, polyesters and inorganic materials are much behind the world's advanced level in China.

In such cases, motor manufacturers sometimes have no choice but to use relatively conservative materials to replace new and more economical and suitable materials.

After talking about two questions in a row, Zhao Siyan's confidence in domestic mine hoists was more or less hit.

However, the two parts Zhao Guoyang mentioned below made her feel like a basin of cold water poured on her head.

"As for the other two parts of the lifting system, the electronic control part and the gate control part, I will discuss it together. The situation of these two parts is very similar. The backwardness in their manufacturing level is also a key factor that domestic products have not yet been able to make the market."

"The current gap between the gate control part of domestic mine hoists is so great that it is completely incomparable in terms of principle, structure, configuration, reliability and performance compared with the products of ABB and Simag, which represent the international advanced level."

"Of course, this situation is understandable. After all, our country started late in gate control, less than twenty years, but this gap does exist..."

After talking about this long paragraph, Zhao Guoyang paused. After they digested it, he followed up and said: "Similar to the gate control part, compared with several companies that represent the international advanced level, the gap between the electronic control part of our domestic mine elevator is also obvious."

"In some key technologies, we rely entirely on the introduction of imported technologies. What is even more heartbreaking is that this gap is still widening..."

Looking at Zhao Guoyang's solemn face, Li Zhaohe frowned and looked heartbroken and said, "What the Chairman said is! Due to the lack of high-power electronic control technology, our domestic mine hoists have to rely on imported electronic control systems."

"As far as I know, the maximum single-machine power of the supporting domestic electric motor is 4300 kW, and the test has not been completed yet. Therefore, when encountering high-power projects, the competitiveness of our domestic products is obviously insufficient..."

Zhao Guoyang gently patted Li Zhaohe on the shoulder to show comfort.

The next moment, he continued to speak: "At present, when purchasing large-scale domestic lifting equipment, users often tend to import equipment. Even when some mining projects are bidding, they directly specify imported equipment."

"A few days ago, I asked someone to learn about the procurement of more than 600 large-scale lifting equipment in dozens of newly mined mines in our country throughout the year last year."

"Among these, domestic equipment accounts for less than 5%. The remaining shares are all included by two industry giants, ABB and Ximague."
