Excavators are important equipment in construction and mining operations, and their different tonnage will significantly affect their technical parameters and performance. According to different tonnage, excavators can be divided into three categories: small excavators, medium excavators and large excavators. Each category has its own unique characteristics in terms of technical parameters and application scenarios.
Excavator parameter comparison
| Category | Small excavator | Medium excavator | Large excavator |
| Tonnage | 1-10 tons | 10-30 tons | 30 tons or more |
| Engine power | 15-60 kW (20-80 hp) | 70-150 kW (95-200 hp) | 150-400 kilowatts (200-500 horsepower) |
| Maximum digging depth | 2-4 meters | 4-7 meters | 7 meters or more |
| Maximum digging radius | 3-6 meters | 6-9 meters | 9-15 meters |
| Capacidad del cucharón | 0.05-0.4 cubic meters | 0.4-1.5 cubic meters | 1.5-6 cubic meters |
Small excavators under 10 tons are popular for their compact design and high maneuverability. They are very suitable for operations in small or complex environments, such as urban construction, gardening, pipeline maintenance, etc. It is easy to operate and can complete tasks efficiently in a limited space.
The stability and digging force of 10-30 tons medium-sized excavators of are improved compared to small excavators, and they are suitable for larger-scale construction projects. It has good balance and can provide efficient operating performance in different terrains and conditions. Commonly used in road construction and maintenance, real estate development and large infrastructure construction and earthworks.
Large excavators over 30 tons have strong digging force and a large operating range, and can handle larger volumes of earth, rock and ore. Its stability and carrying capacity far exceed that of small and medium-sized excavators, and it is generally used in large-scale engineering and mining.
