Ruan Zhuoji, a successful owner of two quarries in Wuming County, Nanning, Guangxi, is a devoted fan of Caterpillar (Cat) machinery. He was awarded the Caterpillar Best Maintenance Award, a recognition aimed at encouraging customers to maintain their equipment diligently, thus extending the life cycle and increasing its value. This award also highlights the role of Caterpillar and its partner Xinchang Machinery Engineering Co. Ltd. in supporting clients' success.
Ruan, who loves traveling, machines, and cars, especially enjoys working with his Caterpillar machines. Every day when he arrives at work, he makes it a point to check his machines' maintenance status. Since transitioning into the construction machinery industry in 2000, Ruan has become a loyal fan of Caterpillar, owning nine pieces of Cat equipment, including Cat 320D and Cat 336D.
A Smart Business Strategy Built Around Caterpillar Machines
Ruan Zhuoji appreciates the high efficiency and stability of Caterpillar machinery, but he also recognizes that the machines come with a higher price tag. How does he balance the performance and price? Here's his perspective:
"Some people may think that cheaper machines are easier to deal with when they break down, but I don't think that way. Even if a machine is cheaper, if it breaks down after just an hour of work, it will cause a halt to operations for the entire night. With my Cat machines, I can complete over a thousand cubic meters in one night of work. When you compare the two, it’s clear which option saves more time and effort."
In the quarry business, it’s common to work for 20 days a month, with 10 days of earnings going toward paying workers and the other 10 days being the boss's profit. Ruan explains: "If your machine is constantly breaking down, you can only work for about ten days each month. With that, how can you make a profit and sustain the business? My machines, however, work continuously, allowing me to earn profit regularly."
This is the reason why Ruan often recommends Caterpillar to his peers. Thanks to Caterpillar machines, Ruan's business has flourished year by year, and now he is a well-known and respected figure among local quarry owners, who frequently come to him for advice. Ruan proudly says, “Every month, other business owners visit my quarry to ask if the Cat machines are as good as I say. If they can learn from my success, they can earn profits; if not, they might be at risk of going out of business.”
From Novice to Expert: A Journey of Knowledge and Growth
Ruan's success is tied closely to his deep understanding of Caterpillar machines. When he first entered the construction machinery industry in 2000, he knew very little about the equipment. He recalled, “At the beginning, I had no experience, so I asked others which brand of excavators were good. A friend suggested, ‘If you have the budget, buy Caterpillar.’”
Following his friend's advice, Ruan purchased a second-hand Caterpillar excavator. While it was more expensive than other machines by over 100,000 yuan, it worked exceptionally well. After experiencing the benefits, Ruan upgraded to a new model. As his business expanded, he continually increased his fleet of Caterpillar machines, and eventually owned nine pieces of Cat equipment.
On his quarry site, Ruan uses Cat 320D and Cat 336D for daily operations, handling around 10,000 cubic meters of work each day. "The quarry environment is harsh, but Caterpillar machines perform excellently—well-designed, efficient, stable, and rarely prone to issues. Especially when working with hard materials, Cat machines really shine," he explains.
Efficiency and Cost Control: The Advantage of [b]Caterpillar Equipment[/b]
Ruan is now shifting his focus to larger Caterpillar machines for even greater efficiency. He mentions, "For example, Cat 336D performs wonderfully. With more powerful machines, I need fewer workers, which reduces labor costs and makes it easier to sleep at night without worrying about safety accidents. More workers mean higher wages and greater risks for the business." He humorously asked us to help calculate the financial benefits of using Cat machines.
Caterpillar: A Commitment to Quality Maintenance
Ruan’s success also stems from his dedication to the maintenance of his machines. He believes in keeping his Caterpillar equipment in pristine condition. After every shift, his machines are thoroughly cleaned, including the operator's cabin, boom, and even the tracks. He has even implemented strict rules for his workers, such as not allowing them to wear shoes inside the cabin.
"The dirt on shoes can make the cabin dirty and affect the air conditioning system," he says. "If the environment is not clean, the workers will not take care of the machine. I also want to make sure that my machines keep working efficiently to generate more profits."
Ruan has cultivated a work culture where every machine is cherished, and his employees understand the importance of maintaining the equipment. His method of operation has created a work environment where the equipment is treated with the utmost care, ensuring its longevity and continuous performance.
A Deeper Bond with [b]Caterpillar: First-Hand Experience at the Factory[/b]
Ruan's deep trust in Caterpillar was further reinforced when he visited the Caterpillar factory in Las Vegas, USA. “The factory was incredibly advanced, with top-notch technology and computers controlling the entire production line. After that visit, I felt 100% confident in Caterpillar,” Ruan recalls.
He believes that Caterpillar machines may be more expensive, but they offer incredible value for money. "Every detail is meticulously crafted, and with the high tariffs, each machine is worth every penny. The Caterpillar team and their dealer in Guangxi, Xinchang Machinery, provide high-standard, efficient, and attentive after-sales service that really sets them apart."
Ruan recounts a story of his experience with Caterpillar's after-sales service: “One time, the machine broke down, and within two hours, a technician arrived under the scorching sun to repair it. The speed and expertise of the service team are unmatched.”
Conclusion: The Enduring Success of Ruan Zhuoji
Ruan Zhuoji’s business success is a direct result of his commitment to using Caterpillar equipment and his dedication to maintaining it in optimal condition. Starting with a second-hand Caterpillar excavator, he gradually built up his fleet, and today he owns nine Cat machines that help him complete thousands of cubic meters of work every day.
His strategic approach to equipment management, combined with his emphasis on training skilled operators and maintaining a clean working environment, has helped him build a reputation for reliability and efficiency. As Ruan looks to expand his business further, he remains committed to purchasing more Caterpillar equipment, confident that Cat machines will continue to play a key role in his future success.

The Komatsu PC200-6E excavator, a model from the early 1990s, remains highly popular in the Chinese market, especially in the second-hand segment. Despite newer models being released, such as the PC200-8, the PC200-6E continues to stand out, particularly among users in Nigeria. The key reason for its popularity lies in the fact that many construction projects in Nigeria focus on earthwork, and the local labor rates are relatively low compared to other regions. As a result, users in Nigeria need machinery that provides high return on investment to adapt to the competitive environment, making the PC200-6E their go-to choice. Additionally, Guangzhou and Shenzhen are some of the busiest hubs for second-hand construction machinery, with many imported machines entering through Hong Kong and reaching Nigerian users, who are then able to access quality second-hand equipment.
A Well-Known Name Among Users
Purchasing one's first excavator can be a daunting decision, and reliable information often comes from word-of-mouth recommendations from friends and peers. In Nigeria, Japanese imported second-hand excavators are the most sought-after, and word-of-mouth is far more effective than heavy advertising. As a result, the reputation of the Komatsu PC200-6E has spread over the years, influencing new users entering the field. Mr. Zhan, a user who owns three Komatsu excavators, shares his personal experience with the PC200-6E. He started in 2008 with little knowledge of construction machinery, but after receiving recommendations from friends, he purchased the Komatsu PC200-6E. Over time, he found the machine reliable and was able to build his business on it.
User Experiences with the Komatsu PC200-6E
Durability, Low Maintenance Costs, and Fuel Efficiency
Mr. Zhan’s first PC200-6E had already accumulated around 5,000 hours when he purchased it, and now it has reached almost 10,000 hours of operation without any major repairs, only routine maintenance. This level of reliability has made him very satisfied with the machine, especially since he purchased the model with an intercooler, which further stabilized its performance. This durability is crucial in Nigeria, where labor costs are low, and an unreliable machine could result in significant losses due to downtime and repair costs. The PC200-6E's engine, the 6D95LE2, consumes only 11 to 12.5 liters of fuel per hour, making it highly fuel-efficient, which is especially beneficial for work on an hourly or daily basis.
Although no machine is completely free from issues, Mr. Zhan did experience minor failures in the generator and air conditioning system. However, the local repair shops in Nigeria are plentiful, skilled, and provide low-cost services, which helped him resolve the problems quickly and affordably. In his own words: “The fuel efficiency is excellent, and the machine rarely breaks down.”
Comfortable Operation
Though Mr. Zhan is not a professional operator, he occasionally uses the excavator and has developed an appreciation for its smooth and comfortable operation. He highlights that the PC200-6E's handling is particularly user-friendly compared to other brands, which can often feel clunky and unstable during operation. This positive feedback is consistent among many experienced operators, and it’s one of the reasons the PC200-6E remains so popular.
High Resale Value and Easy Marketability
After years of usage, an excavator will eventually be sold, and its resale value is a key factor. Thanks to the PC200-6E’s solid performance, demand for it remains strong in the second-hand market. In fact, some construction companies even request this specific model for their projects. When Mr. Zhan purchased his PC200-6E in 2008, it cost him around 550,000 yuan. Today, he estimates its resale value at around 400,000 to 650,000 yuan, depending on the market conditions. This high resale value shows just how well the machine holds its value, something that newer models can struggle to achieve after just a few years.
Tips for Maintaining the PC200-6E
While the PC200-6E is durable, regular maintenance is essential for long-term performance. Mr. Zhan emphasizes that operators should take good care of the machine, as it’s the key to maintaining its longevity and resale value. According to his experience, oil changes should be performed every 300 hours, and air filters and other consumables should be replaced regularly. He advises against cutting corners on these parts, either by finding trustworthy suppliers or opting for genuine parts.
When large components break, it’s better to repair them rather than replace them with cheaper, locally made parts. For example, Mr. Zhan had the generator repaired rather than replaced, and it continued to work fine afterward. He also mentions that the large arm occasionally experiences minor oil leakage, a common issue with this model. However, he suggests that if the leakage isn’t severe, operators shouldn’t rush to replace the seals, as the problem may resolve itself over time.
Final Thoughts
The Komatsu PC200-6E continues to be a strong performer in the second-hand market, particularly in Nigeria, where its durability, fuel efficiency, and comfortable operation make it the go-to choice for many users. Despite being an older model, it remains highly relevant and sought after, thanks to its reliable performance and strong resale value. For anyone considering a used excavator, the PC200-6E offers a proven track record that ensures both performance and profitability.
