What models are there for excavators?
With the rapid development of the infrastructure industry, excavators, as important equipment in construction machinery, have become increasingly diversified in their models and functions. This article will sort out the mainstream excavator models currently on the market and demonstrate their characteristics and application scenarios through structured data.
1. Excavator model classification
Excavators can be divided into the following categories according to tonnage, power type and purpose:
| Classification criteria | Model category | Representative model |
|---|---|---|
| by tonnage | small excavator | 1-6 tons (such as: Komatsu PC30, Carter 306) |
| medium excavator | 6-30 tons (such as: Sany SY135, XCMG XE200) | |
| Large excavator | More than 30 tons (such as: Hitachi ZX870, Volvo EC480) | |
| Press power | diesel power | Most traditional models |
| Electric/Hybrid | SANY SY16E, Carter 320GC electric version | |
| By use | Standard excavator | General type (such as: Kobelco SK200) |
| Special for mines | Extended arm type (such as: Liebherr R9800) | |
| Micro special | Tailless rotation type (such as: Kubota U10) |
2. Comparison of parameters of popular models
The following is a comparison of the technical parameters of the top ten domestic excavator models in 2023:
| Ranking | Model | Tonnage | Engine power | Bucket capacity | Selling price range |
|---|---|---|---|---|---|
| 1 | SANY SY75 | 7.5 tons | 42kW | 0.28m³ | 280,000-320,000 |
| 2 | XCMG XE60 | 6 tons | 36kW | 0.23m³ | 250,000-280,000 |
| 3 | Carter 306 | 6.2 tons | 43kW | 0.25m³ | 350,000-400,000 |
| 4 | Komatsu PC130 | 13 tons | 69kW | 0.52m³ | 650,000-750,000 |
| 5 | Liugong 906D | 6 tons | 38.5kW | 0.22m³ | 220,000-260,000 |
3. Guide to purchasing essentials
1.Working condition matching: Tailless models below 6 tons are preferred for municipal projects, and equipment above 30 tons is required for mining operations.
2.Fuel consumption performance: Taking Sany SY75 as an example, its intelligent fuel-saving system can reduce fuel consumption by 15%.
3.Maintenance cost: Domestic brand parts are supplied faster. For example, the maintenance cycle of XCMG XE60 is 500 hours.
4.technology trends: Newly launched electric excavators in 2023 generally have remote monitoring functions.
4. Latest Industry Trends
According to data from the Construction Machinery Association, excavator sales increased by 12% year-on-year in the third quarter of 2023, of which 6-ton small machines accounted for 45%. Intelligence has become a new trend, and many manufacturers have launched unmanned aircraft models equipped with Beidou navigation system.
It is particularly worth noting that driven by the "double carbon" goal, the market penetration rate of electric excavators has increased to 8%, and is expected to exceed 20% in 2025. The latest SY19E electric micro-excavator released by Sany Heavy Industry can achieve 8 hours of continuous operation using the power swap mode.
From the above analysis, it can be seen that the selection of excavator models requires comprehensive consideration of the operating environment, budget and technical requirements. It is recommended that users inspect the performance of the equipment on site before purchasing and pay attention to the after-sales service policy provided by the manufacturer.
