Guide to purchasing second-hand excavators: Which brands are more trustworthy?

In the fields of construction, mining, and infrastructure development, second-hand excavators are highly favored due to their high cost-effectiveness. However, faced with numerous brands and models on the market, choosing a second-hand excavator with reliable performance and reasonable maintenance costs has become a challenge for many buyers. This article will provide a detailed analysis of the advantages and disadvantages of several mainstream brands to help you make an informed purchasing decision.

 1. Japanese brands: representatives of durability and value retention

 1. Komatsu

As a global construction machinery giant, Komatsu excavators are renowned for their excellent durability and stable performance. In the second-hand market, models such as Komatsu PC200 and PC300 are particularly sought after due to their high precision hydraulic system and long engine life. Even machines that have been used for 5-8 years can still maintain over 80% of their work efficiency as long as they are properly maintained. However, it should be noted that the price of original Komatsu parts is relatively high, making maintenance costs relatively expensive.

 2. Hitachi Construction Machinery

The Hitachi ZX series performs exceptionally well in the second-hand market, especially models such as the ZX200 and ZX330. Its energy-saving technology is leading, and its fuel economy is excellent, making it suitable for long-term high-intensity operations. The cab design of Hitachi excavators is user-friendly and offers high operational comfort, which is highly favored by drivers. When purchasing, it is important to check the condition of the hydraulic pump and swing motor, as these are common wear parts in Hitachi models.

 3. Kobelco

Kobelco excavators are renowned for their innovative hybrid technology, with second-hand models such as SK210H and SK350LC demonstrating outstanding fuel efficiency. Maintenance of Kobelco equipment is relatively straightforward, with a well-designed electrical system resulting in a low failure rate. However, it is important to note that its rubber tracks wear out quickly under harsh working conditions, so the condition of the tracks should be carefully inspected before purchase.

 II. Korean brands: the choice of cost-effective

 1. Hyundai

Modern R-series excavators (such as the R220 and R335) are widely available in the second-hand market and priced relatively affordably. These modern devices feature a universal design, with many components shared with Doosan, thereby reducing maintenance costs in the long run. However, their hydraulic system has a slightly slower response time, making them unsuitable for work scenarios that demand extreme precision.

 2. Doosan

The Doosan DX series (DX225, DX300) is favored by small and medium-sized engineering companies due to its robust structure and good adaptability. The price of Used Doosan excavators is usually 15-20% lower than that of Japanese brands of the same level, but the performance gap is not significant. Special attention should be paid to the condition of their engines, as some older models have issues with early wear and tear of the turbocharger.

 III. European and American brands: professionalism and high performance

 1. Caterpillar

Caterpillar stands as a benchmark in the construction machinery industry, with its second-hand models such as CAT 320 and CAT 336 being highly esteemed in large-scale engineering projects. The heavy-duty capacity and adaptability to harsh working conditions of Caterpillar equipment are unparalleled, yet its price is notably higher than that of other brands. When purchasing second-hand Caterpillar equipment, it is recommended to choose equipment with complete original factory maintenance records, as its complex electronic control system requires professional maintenance.

 2. Volvo

The Volvo EC series (EC210, EC360) stands out in the second-hand market due to its excellent environmental performance and low-noise design. Volvo's hydraulic system is precise and operates smoothly, making it particularly suitable for urban construction. However, its electronic system is relatively complex, and maintenance requires specialized equipment. It is recommended to conduct a comprehensive diagnosis before purchasing.

 3. Liebherr

Liebherr of Germany represents the top-tier craftsmanship in construction machinery. Used models such as R914 and R936 excel in mining and large-scale earthmoving projects. Liebherr machines are extremely durable, with many machines maintaining good condition even after exceeding 15,000 hours of use. However, it should be noted that the supply cycle for its spare parts is relatively long, and emergency repairs may require waiting.

 IV. Domestic Brands: Rapidly Rising Competitors

 1. SANY Heavy Industry

Sany SY series excavators (such as SY215, SY365) are becoming increasingly common in the second-hand market. They offer a significant price advantage, typically priced at only 50-60% of imported brands of the same level. In recent years, Sany's quality has improved significantly, but there is still room for improvement in the stability of its electronic systems. When purchasing, priority should be given to near-new machines that are less than 3 years old.

 2. XCMG

The XCMG XE series, especially models such as the XE200 and XE370, has gradually built a reputation in the second-hand market. The structural strength of XCMG equipment is commendable, making it suitable for heavy-duty applications such as mining. However, its hydraulic system efficiency is slightly lower, and fuel consumption is relatively higher.

 3. LiuGong

The Liugong CLG series (such as CLG922E, CLG950E) is renowned for its simplicity and reliability, with easy maintenance, making it suitable for medium-intensity tasks such as infrastructure maintenance. The prices of second-hand Liugong machines are highly attractive, but it is important to note that early models may have issues with aging seals.

 V. Key considerations for purchasing a used excavator

1. Hours of use: The ideal range is between 5,000-8,000 hours, and careful evaluation is required for usage exceeding 12,000 hours

2. Maintenance records: Complete original manufacturer's maintenance records significantly enhance the reliability of the equipment

3. Operating condition history: Wear and tear of mining equipment is usually more severe than that of ordinary earthwork equipment

4. Engine status: check the color of exhaust smoke, abnormal noise, and stability of power output

5. Hydraulic system: Test whether each action is smooth and check for any leakage

6. Structural component condition: Inspect the boom, arm, and bucket for any cracks or excessive wear

7. Tires/tracks: The replacement cost is high and needs to be included in the total cost of ownership

8. Electronic system: Ensure that all instruments and sensors function properly

 VI. Summary of brand recommendations

- Most stable value brand: Komatsu, Caterpillar

- Best value for money: Hyundai, Doosan

- Most suitable for heavy-duty conditions: Liebherr, Caterpillar

- Most suitable for urban construction: Volvo, Kobelco

- Choices when budget is limited: SANY, XCMG

Regardless of which brand you choose, it is recommended to conduct a comprehensive evaluation of the used excavator through a professional testing agency, while also considering the local after-sales service network and parts supply situation. A suitable used excavator can not only save initial investment, but also create sustained value for you.
