Mini excavators vary significantly in performance, application scenarios and functional positioning depending on their tonnage. The following is a detailed comparison and function analysis of common tonnage segments (below 1 ton, 1-3 tons, 3-5 tons):
1. Features of below 1 ton (0.8-1 ton):
Smallest volume: width can be as narrow as 70cm, height less than 2 meters, light weight (about 800kg-1 ton).
Limited power: diesel engine power is about 10-15kW, digging force ≤10kN, bucket capacity 0.03-0.05m³.
Core role:
Extremely narrow space operations: such as indoor demolition, basement construction, elevator shaft excavation.
Fine operation: gardening landscaping (tree pit excavation), soil arrangement in greenhouses.
Low-intensity tasks: light material handling (sand, broken bricks), small trench backfilling.
2. 1-3 tons (mainstream: 1.5 tons, 2 tons, 3 tons) Features:
Good balance: width 1-1.3 meters, power 15-25kW, bucket capacity 0.05-0.1m³.
Multi-functional adaptation: standard quick-change interface, compatible with hydraulic hammer, auger and other accessories.
Core functions:
Urban infrastructure: municipal pipeline laying, sidewalk renovation, septic tank excavation.
Agriculture/forestry: orchard fertilizer ditch excavation, vineyard pile foundation drilling, forestry wood handling.
Small earthworks: self-built house foundation, swimming pool excavation, rural road maintenance.
3. 3-5 tons (3.5 tons, 4 tons, 5 tons) Features:
Power improvement: power 25-40kW, digging force 15-25kN, bucket capacity 0.15-0.2m³.
Enhanced stability: widened crawler chassis, suitable for slope operations.
Core functions:
Medium-sized earthwork projects: rural water conservancy ditch excavation, small river dredging.
Construction sites: basement earthwork excavation, pile foundation treatment, building material loading and unloading.
Industrial scenarios: equipment foundation construction in factories, material classification in waste yards.
Tonnage and engineering requirements can maximize the value of equipment!
