In the bustling construction site of Qinzhou, Guangxi, a Caterpillar (Cat) 336D excavator fills a 20-cubic meter truck roughly every three minutes. Standing nearby with a satisfied look on his face is Xuan Yousheng, a well-known private enterprise owner in the engineering machinery industry. He is one of the most trusted names in the industry and a proud recipient of the Caterpillar Loyalty Award. This prestigious award recognizes customers who boost efficiency and accelerate success, showcasing the strong bond of mutual support, trust, and collaboration between Caterpillar, its dealer Xinchang Machinery Engineering Co. Ltd., and its customers.

A Turning Point: Discovering the Power of Caterpillar
Xuan’s journey with Caterpillar machines began only five years ago, when they were still a rare sight in Qinzhou. Back then, many people had to rent machinery from Nanning, the provincial capital. Xuan was no exception. However, in 2006, as Caterpillar’s dealer network expanded to Qinzhou through Xinchang, Xuan finally realized that he could conveniently purchase Cat excavators in his hometown. Excited by this opportunity, he bought his first Cat 320C excavator that very year. Little did he know, this machine would become the foundation of an unbreakable relationship with Caterpillar and Xinchang.

Saving a Million-Yuan Investment: The Night of the Flood
Every year between May and August, Guangxi faces its rainy season. On one such rainy evening, Xuan’s Cat 320C was working in the mountains. Due to the low-lying terrain, the river water began rising, and the excavator could not move to higher ground. Seeing his investment of over one million yuan in danger of being submerged, Xuan frantically called Xinchang for help.
Though it was already after hours, Xinchang responded immediately. Two technicians were dispatched and arrived at Xuan’s site in Qinzhou by 8 p.m. The heavy rain did not deter them from their mission. The technicians quickly started “rescuing” the machine, applying oil and protecting the engine to prevent water damage. By 2 a.m., they used another Cat excavator to pull Xuan’s Cat 320C out of the sand, saving his investment from the floodwaters.
The technicians were soaked to the bone and shivering from the cold, but Xuan was deeply moved by their dedication. Over time, he became friends with them, and their bond extended beyond work. This act of support from Xinchang was not an isolated case. The company’s repair teams often travel under harsh conditions to ensure their customers’ equipment keeps running smoothly, no matter the time or terrain.

Mutual Trust and Support Through Tough Times
After surviving the rainy season, Xuan faced yet another challenge—the global financial crisis of 2008. The sudden drop in commodity prices severely affected his business, as mineral prices halved. With monthly payments of over 60,000 yuan for the Cat excavators he had purchased on finance, combined with the wages of his workers, Xuan found himself in a cash flow crunch.
In this difficult situation, Xuan reached out to Xinchang and Caterpillar, requesting that they avoid stopping the machines during the busy construction period, despite his temporary inability to make payments on time. Caterpillar and Xinchang, known for their customer-centric services, understood his predicament and offered him flexible repayment options. While Xuan ultimately managed to make the payments on time, the humane support from Caterpillar and Xinchang gave him peace of mind during the crisis.
Through this challenging time, Xuan’s trust in Caterpillar and Xinchang only grew stronger. The excellent performance of Cat excavators and the efficient after-sales service from Xinchang played a significant role in sustaining his business during tough economic conditions.

Reaping Rewards: Timely Payments and Increased Efficiency
Having weathered the rainy season and the financial crisis, Xuan saw the rainbow after the storm. In the construction industry, it is not uncommon for contractors to face delays in receiving payment after completing projects. However, Xuan’s experience was different—his payments were almost always prompt.
The secret to this “luck” lay in the efficiency of his Cat excavators. Xuan proudly shared, “Because Cat excavators work quickly and efficiently, clients are always satisfied with the progress. They don’t want me to leave the job site, which naturally ensures timely payments.”
Though Cat excavators are priced higher than other brands, their superior quality, durability, and reliability mean fewer breakdowns and less downtime for repairs. As Xuan wisely pointed out, "The cost difference between Cat and other machines is negligible when you consider the costs incurred during repairs and delays." He further added, “Projects like the Three Gorges Dam demand machines that can work continuously without delays, and Cat machines are always the first choice because they can handle the toughest tasks.”

Growing Business: Expanding with Caterpillar
Relying on Caterpillar machinery, Xuan’s business continued to thrive. He became meticulous about fuel costs and efficiency, calculating, “If I spend 7,000 yuan on fuel, I can earn 13,000 yuan in work. If you spend 5,000 yuan on fuel, you only earn 10,000 yuan. Which is the better deal?”
Since his first purchase, Xuan has expanded his fleet by adding five more Cat excavators. He often encourages his friends and colleagues to buy Cat machines, citing their exceptional performance and the superior service from Xinchang.
The thriving demand for earthmoving services in Qinzhou has also contributed to Xuan’s success. From 2008 to the present, Qinzhou has seen a surge in large-scale infrastructure projects, including the construction of bonded port areas, industrial parks, and oil refineries. The increasing demand for earthmoving services has led many in the region to follow Xuan’s example and invest in Caterpillar machinery.
In fact, the sales of Caterpillar machines in Qinzhou doubled from 2008 to 2009, with over 60% of the excavators used in large projects, such as the Qinzhou Port Reclamation and PetroChina’s Refinery, being Caterpillar machines.

Conclusion: A Strong Partnership Built on Trust
Xuan Yousheng’s journey with Caterpillar has been one of mutual trust, shared growth, and continued success. From his first Cat 320C excavator to his expanding fleet of Cat machines, Xuan has witnessed firsthand the reliability and efficiency of Caterpillar equipment.

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.

Fortunately, the manufacturer’s repair service was quick to respond, and the necessary parts were easy to obtain, causing minimal disruption to his work.
  

The Komatsu PC60-8 is a compact excavator introduced by Komatsu in 2011, and it made its debut at the Beijing BICES construction machinery exhibition that year. Positioned between the PC56-7 and PC70-8 models, the PC60-8 is ideal for earthworks. It features the high-power SAA4D95LE turbocharged engine, combining a small footprint with powerful performance, improved combustion, and excellent thermal efficiency.

1. Appearance & Comfort
   "HappyHunter" is very satisfied with the appearance of the Komatsu PC60-8. The cab offers ample space and the seat is comfortable, making the overall driving experience quite enjoyable.
   
2. Toolbox Design
   The PC60-8’s toolbox is convenient, though it’s a bit small—just enough space to fit one grease bucket. Despite its small size, it proves to be a practical feature.
   
3. Bucket Size
   The machine comes with a 0.3m³ rock bucket. While this bucket felt a bit oversized for most of the earthworks tasks, "HappyHunter" had initially wanted to switch to a different bucket but couldn't as the sales company did not have the compatible earthworks bucket available.
   
4. Walking Performance
   The walking performance varies in different modes. In “turtle mode,” when the throttle is at six, turning can feel a bit difficult. In “rabbit mode,” however, a seven-speed throttle is necessary to achieve the desired walking speed. Compared to the PC60-7, the PC60-8’s walking speed isn’t as quick.
   

1. Paint Quality Issue
   Although "HappyHunter" takes good care of the machine, he noticed the paint started bubbling on the rear of the machine after just 500 hours. This raises concerns about the durability of the paint job.
   
2. Fuel Consumption
   While the PC60-8 delivers solid performance, its fuel consumption is higher than the previous PC60-7 model. "HappyHunter" measured that the fuel tank capacity is smaller, and the fuel consumption is noticeably higher.
   
3. Joystick Feedback
   In the EO standard mode, using six throttle settings makes the joystick feel heavy. In the P power mode, however, the joystick feels lighter with the same throttle setting. This discrepancy might affect the precision and comfort of operations.
   
4. Rotation Speed and Force
   While the PC60-8’s power is impressive, its rotation speed is somewhat slow. The response time for compound actions is quick, but overall, it feels less agile compared to other models in its class.
   

On August 8, 2012, the new generation ZY60 mini excavator, powered by Quanchai engines, rolled off the production line at Rongsheng Machinery's facility in Hefei. The use of a domestic engine, particularly from Quanchai, has caught the attention of many industry observers. While the use of local engines in small excavators is not new, the timing of this product’s release – at a critical moment in the collaboration between Rongsheng Heavy Industries and Quanchai Power – has sparked curiosity and concerns among users.
A New Player with Local Power
Currently, the majority of small excavators in China still rely on foreign engine brands such as Cummins, Isuzu, Yanmar, Mitsubishi, and Perkins. However, some manufacturers, including Yuchai, Changchai, and Quanchai, have ventured into using domestic engines for their products, especially in machines under 5 tons. The ZY60 is a notable addition to this category, and its launch by Rongsheng Heavy Industries has generated mixed reactions in the market.
Some experienced users from the machinery community have expressed their views on this new development, with varied opinions on the use of domestic engines in excavators.

• User "罩得住": While domestic engines like Weichai and Yuchai are mainstream, small excavators with domestic engines tend to have shorter lifespans. Many new domestic mini excavators are prone to issues, such as air conditioning failures and oil leaks, which can affect long-term durability.
  
• User "沐浴阳关": The small excavator market is seeing growth, especially due to lower purchase costs. The introduction of the ZY60 means more competition in the market. The benefit of using domestic engines is that they lower both purchase and maintenance costs, making it easier for users to manage repairs, though it may come with higher failure rates.
  
• User "汗鱼": The use of domestic engines in small excavators is not unprecedented. The key factor is whether the engine’s power output is well-matched to the machine’s design. The real challenge lies in the selection of hydraulic components.
  
• User "堕落天使": Domestic engines like Yuchai have been used in small excavators for some time. The ZY60 is not a groundbreaking example; it is a cost-effective machine. While domestic engines work in small excavators, they tend to be noisier and have shorter lifespans.
  

The Hitachi ZX70 mini excavator has gained popularity among users for its excellent fuel efficiency and stable performance. Discussions about the ZX70, especially regarding fuel consumption and machine performance, have been quite active in the machinery community. Below is a user report from chenwei, who has used his Hitachi ZX70 for 2100 hours, providing an in-depth look into his experience with this machine.
Purchase Background and Reason for Choosing the ZX70
Chenwei previously owned a Yuchai 85 mini excavator. In December 2010, he decided to sell it and purchased a Hitachi ZX70 for 480,000 RMB. He considered mini excavators from Komatsu and Caterpillar, but ultimately chose the ZX70 due to its larger size, inclusion of a bulldozer blade, and more favorable pricing. Since then, this ZX70 has been in operation for 2100 hours.
