The applicable scenarios of excavators of different tonnages

Excavators are generally classified into four types based on tonnage: micro, small, medium and large. The tonnage classification directly determines their working efficiency and applicable environment. The specific scenarios are as follows:
Mini excavator (1-5 tons) ‌
Suitable for narrow or restricted Spaces, such as municipal greening, interior decoration, courtyard renovation and fine operations in farmland and orchards ‌.
Highly flexible, capable of efficiently completing small-scale earthwork and pipeline laying tasks in densely populated urban areas ‌.
Small excavator (5-15 tons) ‌
It is mainly used in municipal engineering, landscaping, rural homestead construction and small-scale earthwork excavation ‌.
The bucket capacity is relatively small (0.2-0.3 cubic meters), taking into account both mobility and efficiency, such as in pipeline maintenance and farmland water conservancy projects ‌.
Medium-sized excavator (15-35 tons) ‌
It has strong versatility and is suitable for road construction, house foundation excavation, mine stripping and large-scale earthwork projects ‌.
The standard bucket capacity is approximately 0.8-1.5 cubic meters, suitable for medium-intensity operations, such as building foundation excavation and dam construction ‌.
Large excavators (over 35 tons) ‌
Designed specifically for high-intensity scenarios such as open-pit mining, port construction, large-scale infrastructure projects and heavy earthwork handling ‌.
The bucket capacity can reach 1.6-4.5 cubic meters, with extremely high efficiency, but it requires open ground support ‌.
Selection suggestions
Model matching ‌ : The tonnage code is usually related to the model number (for example, "200" represents the 20-ton class), but it must be combined with brand rules (for example, "320" for caterpillar is 20 tons, and "SY215" for Sany is 21.5 tons) ‌.
Scene optimization ‌ : microcomputers are preferred in narrow Spaces, medium-sized machines are selected for earthwork, and large machines are used in mining operations ‌.
When making an actual selection, the working environment, efficiency requirements and costs should be comprehensively considered to avoid efficiency loss ‌ caused by the mismatch between tonnage and the scene.
