In the ever-changing construction machinery market, choosing a reliable second-hand excavator is like an investor seeking blue-chip stocks in the stock market. Once you make the right choice, the returns will be remarkable. Today, we are going to introduce the Caterpillar 320DL, which is undoubtedly a shining “blue-chip stock” in the second-hand excavator market.

1. On-Site Performance: A Capable Workhorse for Efficient Operations

When stepping onto a construction site, the Caterpillar 320DL looks like a well-trained elite engineer, immediately catching everyone’s attention. It is painted in the classic yellow, with a robust build, and beneath its tough exterior lies tremendous power. With a standard bucket capacity ranging from 0.8 to 1.0 cubic meters, when the bucket cuts into the soil layer, the bucket digging force of 138kN bursts out instantly. Combined with the arm digging force of 101kN, even the toughest geological conditions can be easily conquered. Even in harsh working conditions with boulders and dense clay, it can work steadily, loading earth accurately one bucket after another, and its working efficiency far exceeds that of its peers.

When it comes to relocating on the site, its flexibility is not compromised at all. With a traveling speed of 5.5 km/h at high gear and 3.2 km/h at low gear, it can move quickly around the site. The swing speed of 11.5 revolutions per minute enables it to turn and reverse smoothly without any wasted idling time. When encountering steep slopes on the construction site, its climbing ability of 70% shows its full advantage. The chassis and tracks grip the ground firmly, allowing it to climb safely and steadily, thus keeping the construction progress firmly under control throughout the process.

2. Quality Assurance: A Durable Model Built to Last

In the field of construction machinery, the durability of equipment directly affects the return on investment, and the Caterpillar 320DL excels in this regard, delivering an excellent performance with its outstanding quality. The sealing performance of the whole machine is remarkable. Upon closer inspection, the engine compartment and hydraulic pipelines are as clean as new, with no signs of oil leakage at all. The core components are fully protected, and the wear is minimal.

This is attributed to Caterpillar’s exquisite craftsmanship and strict quality inspection system. The equipped C6.4 ACERT engine has a power output of 140kW. The six cylinders work in harmony, and the reasonable design of the cylinder bore and stroke endows it with stable and powerful power output, enabling it to withstand high temperatures, heavy dust, and wet and muddy conditions. Coupled with an excellent hydraulic pump that precisely controls the hydraulic flow, the movements of the boom are smooth, reducing the impact and wear between components and minimizing the failure rate. With proper maintenance, it can serve for more than 10 years without difficulty, ensuring the long-term and stable operation of construction projects.

3. Acknowledging the Shortcoming: Addressing the High Fuel Consumption for Long-Term Benefits

No machine is perfect, and the Caterpillar 320DL is no exception. Its relatively high fuel consumption is an acknowledged shortcoming. During high-intensity operations, the average fuel consumption is around 16 - 24 liters per hour, which looks a bit high compared to some competing models of the same tonnage. However, savvy construction professionals know how to weigh the pros and cons. What it brings in return is tangible high efficiency and excellent performance.

When engaged in mining operations, facing rocks as hard as iron, or in large earthwork projects that require massive earthmoving, the Caterpillar 320DL, with its powerful power and stable performance, can always complete the work ahead of the project deadline. This reduces equipment rental time and labor costs, making the extra fuel consumption negligible.

4. Competitor Comparison: Standing Out with Obvious Advantages

In the highly competitive second-hand excavator market for 20-ton models, there are many rivals. Komatsu PC200 and Hitachi ZX200, for example, each have their own strengths. The Komatsu PC200 is fuel-efficient, consuming about 20% less fuel than the Caterpillar 320DL during operations and has relatively flexible handling. However, when it comes to hard soil layers, its insufficient digging force reveals its weakness, significantly reducing its working efficiency. Additionally, it requires frequent maintenance and has high costs for replacing parts.

The Hitachi ZX200 focuses on intelligence, with an in-vehicle monitoring system that can provide real-time feedback on the equipment’s status and offers a good human-machine interaction experience. However, its structural strength is not satisfactory. Under harsh working conditions, structural deformations and cracks occur frequently, greatly shortening its service life. In comparison, the Caterpillar 320DL stands out with its high performance, low failure rate, and long service life, making it a hot favorite in the second-hand market.

On the Tiedou Second-Hand Excavator platform, the Caterpillar 320DL is waiting for its discerning buyer with its outstanding advantages. If you have ambitious construction plans and hope that your equipment can be a reliable backup for success, don’t hesitate to inquire and inspect the machine immediately. Seize this “blue-chip stock” and let it keep working hard in your construction projects, helping you achieve remarkable progress and unlock unlimited possibilities!
