Estimate your excavator’s bucket capacity easily with our Excavator Bucket Capacity Calculator. Enter bucket dimensions, fill factor, and material density to find bucket volume, adjusted capacity, and load weight in cubic meters and kilograms.
Introduction
Knowing the bucket capacity of an excavator is crucial for planning earthmoving and construction work efficiently. It helps you estimate the number of bucket loads required, calculate total excavation time, and evaluate hauling requirements.
This Excavator Bucket Capacity Calculator allows you to compute the theoretical capacity, adjusted capacity (considering fill factor), and total material weight per bucket based on the type of material.
Formulas for Excavator Bucket Capacity
1. Theoretical Bucket Capacity
The basic volume of the bucket (without considering the fill factor) is calculated using:
Bucket Capacity (m³)=Width (m)×Height (m)×Length (m)
2. Adjusted Capacity (Considering Fill Factor)
The fill factor accounts for how full the bucket actually gets, depending on the material type.
Typical fill factors range from 0.8 to 1.1 (80%–110%).
Adjusted Capacity (m³)=Bucket Capacity (m³)×100Fill Factor (%)
3. Material Weight per Bucket (Optional)
If you know the material density, you can calculate the approximate load weight per bucket:
Material Weight (kg)=Adjusted Capacity (m³)×Material Density (kg/m³)
Example Calculation
Let’s assume the following input values:
- Bucket Width: 1.2 m
- Bucket Height: 1.0 m
- Bucket Length: 1.1 m
- Fill Factor: 90%
- Material Density: 1800 kg/m³
Step 1: Calculate Theoretical Bucket Capacity
Bucket Capacity (m³)=1.2×1.0×1.1=1.32 m³
Step 2: Calculate Adjusted Capacity
Adjusted Capacity (m³)=1.32×10090=1.188 m³
Step 3: Calculate Material Weight per Bucket
Material Weight (kg)=1.188×1800=2138.4 kg
Final Results
- Theoretical Bucket Capacity: 1.32 m³
- Adjusted Capacity: 1.188 m³
- Material Weight per Bucket: 2138.4 kg
