Caterpillar 320D Excavator Review: A Reliable and Efficient Workhorse - MikePhua - 06-28-2025
In this review, we hear from a seasoned excavator operator and forum member, Sun Xuliang (also known as "Da Di Zhi Xing"). Sun, an operator from Ningxia, China, has been active in the excavator industry for several years and is well-known in the online community for his contributions. Notably, before the official launch of the "Iron Armor Car Stickers," Sun took it upon himself to create personalized versions, which sparked a wave of interest in the forum. Additionally, Sun helped guide fellow member "With You Dance Gold" in purchasing a Caterpillar 320DGC, a decision documented in the article "Why I Chose the Caterpillar 320DGC Earthmover Over the Komatsu PC200-8." Sun is also a key point of contact for members in Ningxia, Gansu, Xinjiang, Shaanxi, Inner Mongolia, and Tibet.
Now, let's dive into the performance and experience of using the Caterpillar 320D excavator, as shared by Sun Xuliang.
Operator Background
Sun Xuliang works for an engineering company in Ningxia and has been operating excavators for over seven years. After finishing middle school, Sun began learning excavator operation and gained significant experience with the company’s Hitachi ZX230-1 model. The Caterpillar 320D was the company's new addition, and Sun was given the opportunity to operate it.
Sun’s company primarily focuses on water conservancy, construction, and road engineering, with a fleet of various machinery, including excavators, loaders, dump trucks, and rollers. As one of the most experienced and skilled operators, Sun is highly valued by his company leadership.
Purchase Information
- Purchase Date: March 15, 2010
- Payment Method: Full payment
- Total Price: 1.13 million RMB (including 6,000 RMB for accessories)
- Dealer: Caterpillar Ningxia dealer, Yichu Mingtong
Operator Details
Sun is the primary operator of the 320D, but he also has an apprentice who occasionally helps with simpler tasks. Sun is meticulous about the machine's maintenance and care, often sharing his experiences online. However, there was one occasion where the apprentice accidentally drove the machine into a ditch, which Sun found distressing.
Work Conditions
The Caterpillar 320D is primarily used for road construction, including tasks such as leveling roads, repairing embankments, and digging earth. The terrain is mostly soft sandy soil or hard soil, with no rocks present, making it a typical earth-moving operation.
Work Efficiency
According to Sun, the 320D is highly efficient, with much faster movements compared to the Hitachi ZX230-1. The Caterpillar 320D not only provides superior digging power but also offers better precision in operations, making it a highly suitable choice for earthwork projects.
Fuel Consumption
- Normal Operation (7-8 throttle): 18 liters per hour
- High-intensity Operation (full throttle): 23 liters per hour
Product Performance and Issues
- Engine: Since purchase, the engine has not shown any issues and operates smoothly.
- Hydraulic System: No problems have been encountered with the hydraulic system either.
- Other Issues: The only issue encountered was with the toolbox lock, which became faulty after some use. The key no longer fit into the lock, and while the cost to replace the lock assembly was over 1,000 RMB, Sun chose to forgo the replacement for the time being. Sun also mentioned that the seat is uncomfortable for long hours of operation, and the paintwork on the large and small arms of the machine is somewhat rough and inconsistent.
Sun is highly satisfied with the service provided by Yichu Mingtong, the Caterpillar dealer in Ningxia. The dealer provides timely and efficient maintenance, ensuring the machine remains in top condition.
Parts and Maintenance Costs
While Sun is happy with the overall performance of the 320D, he noted that the parts for Caterpillar machines are relatively expensive. For instance, a barrel of engine oil costs significantly more than that for the Hitachi ZX230-1, and filter parts are also pricier. Despite this, Sun believes the higher price is justified by the quality and reliability of the parts.
Summary
The Caterpillar 320D excavator has long been a top choice in the Caterpillar lineup, and for good reason. Known for its durability, high efficiency, and precise operation, the 320D is widely regarded as a reliable machine. Sun’s feedback aligns with the general perception of this excavator: it excels in earth-moving tasks, with low failure rates and a solid engine. However, the high cost of parts remains a concern for many, especially for individual users focused on operating costs and maintenance expenses. Still, for companies like Sun’s, which have the budget to support it, the Caterpillar 320D is an excellent investment that provides long-term value and performance.
