Recently, China’s technology sector has surged, with technologies like humanoid robots, industrial mother machines, memory chips, flying cars, and more breaking out across the Shanghai Composite Index, the STAR 50 Index, and the ChiNext Index. Among these, the humanoid robot sector saw the highest growth.

At the 2025 Spring Festival Gala, a performance called "Yang BOT" by Yushu Technology in collaboration with Xinjiang Arts College showcased a spectacular humanoid robot appearance.
Audiences from around the world were amazed by the robots, dressed in cotton jackets and joyfully performing the Yangko dance. Their arms, like humans, could precisely control high-speed spinning handkerchiefs and catch and toss them with impressive flexibility and accuracy.

Thanks to a mature supply chain, application scenarios, and strong policy support, humanoid robots in China are moving from concept to application: medical robots performing surgeries, agricultural robots harvesting fruits, industrial robots assembling and processing, and educational robots interacting with students... In the streets of Shenzhen, we even see robot police patrolling, equipped with sirens and body cameras, interacting with citizens.

Over the past decade, the Chinese robot industry has rapidly grown from robotic devices and robotic vacuums to smart navigation robots and now to the dominant humanoid companion robots. The humanoid robot industry is an integrated display of artificial intelligence technology and is expected to reach a market size of 12 billion RMB and 1.5 million units sold by 2030.
According to data from China’s Market Supervision Big Data Center, as of December 2024, there were 451,700 intelligent robot enterprises in the country, with a total registered capital of 6.44 trillion RMB. The number of enterprises has increased by 206.73% compared to the end of 2020 and by 19.39% compared to the end of 2023, showing steady and robust growth.

"Without lubricants, they cannot function."

Although lubricants play a "silent" role, they serve as the "invisible cornerstone" of the robot industry. As a "flowing technology" product, the efficient operation of intelligent robots depends on the protection formed by lubricants and grease, which create a nano-level oil film.

Approximately 80% of the wear and tear on industrial robots is caused by friction and abrasion. High-quality lubricants not only reduce friction and extend the lifespan of machines, but also improve equipment stability and precision, enhancing operational efficiency.

In FANUC, a Japanese robotics company, the maintenance manual clearly states that after three years of operation or 10,000 hours of work, the robot’s six-axis reducer lubricants and J4 axis gear lubricants need to be replaced.

Practical experience also confirms that the better the grease’s wear resistance, the more durable the machine, and the longer the oil change interval.

Take Great Wall Lubricants, a subsidiary of Sinopec, for example. The company conducted a durability test for reducer lubrication with its own products, equivalent to 6,000 hours. At the end of the test, the surface of the reducer showed almost no wear, and the remaining lubricants were still clear amber.

For a robot factory with continuous production, this means equipment can operate for up to 10,000 hours or even longer, i.e., equipment can run for nearly two or three years without needing to stop for oil changes and maintenance. This significantly reduces the frequency of downtime for repairs and increases production efficiency, saving nearly 50% of costs.

The reducer is one of the robot’s core components, with a precise internal structure and stringent requirements for lubricants. Great Wall Lubricants provides superior anti-wear, extreme pressure resistance, and oxidation stability, offering more than 10,000 hours of lubrication protection for robots.

In this field, Great Wall Lubricants' technological innovations are particularly outstanding.

For RV reducers, Great Wall Lubricants has developed SPI-B grease, which offers excellent extreme pressure and anti-wear properties. In the field of harmonic reducers, the company improved earlier greases and developed SPI-Q grease, specially for robot harmonic reducers, bringing aerospace technology to civilian applications and setting a benchmark in the field.
In addition, Great Wall Lubricants has launched a series of specialized oils for industrial robot reducers and SBI-F greases, ensuring the stable operation of industrial robots.

Great Wall Lubricants also led the development of the first publicly available standard for robot joint lubrication products, with their products servicing many domestic and international automotive production line robots, demonstrating multi-dimensional product expansion.

Domestic Lubricants Guarding the "Chinese Blood" of Intelligent Manufacturing

According to the International Federation of Robotics (IFR), by 2030, 1.5 million new industrial robots will be applied in factories worldwide, with over 40% of them in the Chinese market, making China the largest industrial robot consumer country. The continued positive growth of the robot industry will drive an increasing demand for high-quality lubricants.

In fact, because China’s robot research and application began relatively late, there has long been a lack of substitute lubricants for supporting the normal operation of robots. The high maintenance costs had severely restricted the introduction, digestion, absorption, and localization process of robot technology.

Great Wall Lubricants, one of the few companies in the world with the most complete range of lubricants, has been committed to lubrication technology for 70 years. As China’s "flowing technology", it plays an indispensable role in safeguarding the development of China’s robot industry.

Today, the lubricant industry not only breaks the technical monopoly of foreign giants but also significantly reduces the daily maintenance costs of robots, giving Chinese companies more confidence in choosing domestic products.

In the future, Great Wall Lubricants will continue to focus on independent research and development, strengthen cooperation and innovation with domestic and foreign manufacturers, and ensure that more high-end equipment in China runs on "Chinese blood", creating greater social and commercial value through lubricating quality.

With the decline of China's construction industry, the construction machinery industry has also encountered a cold winter.

In the past 40 years, China has produced a large number of excavators. Because the steel body of the excavator is very difficult to wear, old excavators are generally not easy to withdraw from the market. After proper repairs, they can often still work in a brand new posture. Therefore, China's second-hand excavator market is still a very hot market until now.

However, with the downturn in the construction industry, more and more excavator operators and engineering companies plan to sell or have sold their excavators. This makes the Chinese market basically occupied by second-hand excavators.

Sany's new machine sales suffered an unprecedented blow. As a state-owned enterprise, it began to use its political advantages to crack down on second-hand dealers together with the government. They joined the police to interrogate and record second-hand dealers in the way of investigating criminals, in order to intimidate second-hand dealers.

Sany is not the first company to do this. XCMG has already started similar actions. Including but not limited to Alibaba only allows XCMG to operate itself, and does not allow second-hand dealers to participate.

This may be an unprecedented opportunity for overseas buyers, as XCMG and Sany's high-quality excavators may see huge price cuts.

How to buy a used excavator?

Would you click "place an order" online like buying a mobile phone and then wait for delivery at home? If you have this habit, I hope you won't get into trouble.

There must be some details between the excavators sold online and the ones you actually see, and these details are definitely important.

If you want to buy a satisfactory excavator, it is best to see the machine in person or send a representative to see it on site.

• First, choose a salesperson you like. This is the beginning of everything. In the process of communicating with him, you will understand his professionalism, integrity, ability and personality.
  
• Then, determine the model you need. Due to the huge amount of information posted online, salespeople generally do not delete the information of sold machines. The salesperson will help you choose a machine of the same type instead of the one you saw online.
  
• Next, pay a deposit to the company where the salesperson works, and then ask them for an invitation letter to apply for an international visa.
  
• Next, you can fly to your destination to see and choose the excavator you like with your own eyes. In addition to seeing with your eyes, it is best to drive the machine yourself to feel the condition of the machine. After selecting it, you can also negotiate the price.
  
• The most important step may be price negotiation. The same machine has different prices in different countries. For example, the price of Sany excavators in the United States is usually 2.5 times that of China.
