How to Select Bucket Capacity Based on Requirements

The following is a professional guide for selecting bucket capacity, combining operational demands with machine specifications for comprehensive analysis:

I. Tonnage and Bucket Capacity Matching Standards

Mini Excavators (<10 tons)

Recommended Bucket Capacity: 0.1-0.6m³

Suitable Applications: Municipal trenching (0.2-0.5m³ narrow buckets), landscaping

Medium Excavators (10-30 tons)

Standard Bucket Capacity: 0.8-1.5m³

Reduce to 0.6-1.0m³ for rock applications with reinforced material

Large Excavators (>30 tons)

Mining Operations: 1.9-6.0m³ (e.g., XCMG XE380DK at 2.3m³)

Extra-large projects: SY870H-S bucket capacity up to 5-6m³‌

II. Key Selection Factor Comparison‌

Influencing Factor    Recommended Adaptation    Typical Example

Soil Type    Hard rock: Reduce bucket capacity by 20% + reinforced structure    Caterpillar 305.5 rock bucket (0.6m³)‌

Space Constraints    Narrow bucket (width ≤40cm) Sany SY16C (0.23m³ narrow bucket)‌

Hydraulic System    Large bucket capacity requires ≥25MPa pressure    Caterpillar 320DGC hydraulic system‌

III. Economic Calculation Reference‌

For every 0.1m³ increase in bucket capacity:

Efficiency improves by approx. 8%

Fuel consumption increases by 12%

Recommendation:

Understand actual operating conditions

IV. Special Application Solutions‌

Frozen Ground Operations‌

Select 30° forward tilt angle design + Bucket capacity ≤ 80% of standard value

Construction Waste Handling

4-in-1 bucket (soil-rock separation function)

Require inquiry

Obtain customized solution

Important Notes:

Actual loading capacity is 15%-20% less than rated volume

Avoid exceeding tonnage-matched capacity range (e.g., 20-ton machine with 1.5m³ bucket causes sluggish operation)
