An excavator is a multi-functional piece of construction machinery that can be paired with a compatible excavator bucket for each project task such as digging, grading, and clearing. In the infographic below, we’ll explore the 7 different types of excavator buckets to help you choose the right one for the job.
7 Common Excavator Bucket Types
Below, we break down the 7 primary excavator buckets, discussing each type’s design, applications, and unique benefits. This section is ideal for anyone looking to understand the different types of excavator buckets and how they can be matched to specific job requirements.
1. Digging Bucket (Standard Bucket)
Der digging bucket, often referred to as the standard bucket, is the most commonly used attachment for excavators. This bucket is designed for general-purpose excavation tasks, making it the go-to choice for a wide range of jobs.
- Broad and curved design
- Ideal for digging through standard soil types
- Available in various sizes to match different excavator models
2. Rock Bucket
When you’re dealing with hard, rocky terrain, a rock bucket is the perfect solution. This bucket is specifically designed to handle heavy-duty materials like rocks, debris, and compacted soil.
- Reinforced structure with thicker steel
- Strong teeth for breaking through tough materials
- Often features a heavier design for extra durability
3. Grading Bucket
Der grading bucket is designed for tasks that require precision, such as leveling and smoothing out soil or materials. It is particularly useful in construction projects that demand a smooth, uniform surface.
- Flat design with a shallow profile
- Straight edge for creating a smooth, even surface
- Often features additional reinforcement for durability
4. Ditch Cleaning Bucket
A ditch cleaning bucket is designed for cleaning and maintaining ditches, culverts, and drainage systems. Its specialized shape allows it to work efficiently in tight, confined spaces.
- Narrow and long with a deep, curved design
- Built for precision digging in restricted spaces
- Often features additional teeth for cutting through stubborn materials
5. Trenching Bucket
When you need to dig narrow, deep trenches for utilities, pipes, or foundations, the trenching bucket is your best option. This bucket is designed specifically for trenching and can handle the tough job of digging precise channels.
- Narrow, deep design for digging trenches with precise width and depth
- Sharp teeth to cut through soil and compact materials
- Available in various sizes to match trenching needs
6. Skeleton Bucket
Der skeleton bucket is perfect for sifting through materials to separate unwanted debris or rocks from the soil. Its open-frame design allows small materials to pass through, leaving larger materials behind.
- Open-frame design with wide gaps between bars
- Lightweight construction for easy sifting
- Great for separating rocks or large debris from soil
7. Clean-up Bucket
After heavy excavation work, the clean-up bucket helps clear up any remaining loose materials, leaving the site ready for the next phase of construction or landscaping. It is designed to scoop up debris quickly and efficiently.
- Shallow and wide design for fast and efficient debris collection
- Lightweight, often featuring smooth sides to reduce material sticking
- Can handle various types of debris, including dirt, gravel, and small rocks
Excavator Bucket Size Chart
Choosing the right excavator bucket goes beyond simply picking a bucket type; it’s also about matching the size of the bucket to the excavator and the task at hand. An excavator bucket size chart is an essential tool that guides operators in selecting a bucket that fits their machine’s capacity and the project’s demands.
| Bucket Type | Mini Excavator (1–8 tons) | Medium Excavator (10–20 tons) | Large Excavator (20–50 tons) |
|---|---|---|---|
| Standard Digging Bucket | 24–36 inches (0.2–0.4 m³) | 36–48 inches (0.5–0.8 m³) | 48–72 inches (1.0–2.5 m³) |
| Rock Bucket | 18–24 inches (0.1–0.3 m³) | 24–36 inches (0.4–0.7 m³) | 36–48 inches (0.8–1.5 m³) |
| Grading Bucket | 36–48 inches (0.2–0.5 m³) | 60–72 inches (0.7–1.2 m³) | 84–96 inches (1.5–3.0 m³) |
| Ditch Cleaning Bucket | 36–48 inches (0.2–0.5 m³) | 60–72 inches (0.6–1.0 m³) | 84–96 inches (1.5–2.5 m³) |
| Trenching Bucket | 6–12 inches (0.05–0.15 m³) | 12–24 inches (0.2–0.4 m³) | 18–36 inches (0.5–0.8 m³) |
| Skeleton Bucket | 24–36 inches (0.2–0.4 m³) | 36–48 inches (0.5–0.8 m³) | 48–72 inches (1.0–2.0 m³) |
| Clean-up Bucket | 36–48 inches (0.2–0.5 m³) | 60–72 inches (0.7–1.2 m³) | 84–96 inches (1.5–3.0 m³) |
How to Use This Excavator Bucket Size Chart
- Mini Excavators (1–8 tons): Best suited for small-scale projects such as landscaping, utility work, and trenching.
- Medium Excavators (10–20 tons): Ideal for general construction, roadwork, and material handling.
- Large Excavators (20–50 tons): Used in mining, quarrying, large-scale earthmoving, and demolition work.
