10 Different Types of Excavator Buckets

The construction industry is constantly evolving to meet the needs of users and operators within it. Thus, having the right equipment for each job is essential. Choosing the appropriate excavator bucket for your machine is necessary to efficiently address specific job specifications and the type of material being handled. With a vast selection of excavator buckets available, you may not know where to start if you're new or looking to explore other options. We have compiled a list of 10 Different Types of Excavator Buckets and their best uses.

1. Digging Bucket

Commonly referred to as a general-purpose excavator bucket, the digging bucket is the most recognizable attachment. Digging buckets are typically provided with mini diggers and excavators when purchased or rented. Their primary function is to execute bulk digging through soil and rubble in construction, landscaping, or groundworks environments.

The digging bucket often comes fitted with teeth to penetrate tougher, compact ground. These teeth break through material, allowing for scraping into the bucket for movement or removal. Additionally, they can be equipped with a blade for creating flat bottoms in trenches or for use around utilities. Digging buckets are available in various widths to suit the job. For instance, Rhinox mini digging buckets fit excavators from 0.75 to 25 tons, with options of 6", 9", 12", 18", and 24" widths, accommodating applications from small ditches to larger clearances.

2. Rock Bucket

While durable, standard digging buckets may not always be suitable for certain jobs. The rock bucket is a heavy-duty variant reinforced with thicker wear plates and sharper teeth, making it more effective for harsh conditions. It excels at breaking up rocks and abrasive materials commonly found in quarries. Currently, Rhinox does not offer rock buckets.

3. Utility Bucket

The utility bucket is an enhancement of the standard digging bucket, featuring a Uni-tusk — a rounded edge, bolt-on blade. Designed to protect utility workers digging near utilities, the Uni-tusk deflects cables away from the bucket. This unique feature locks the side plates and lip plate, increasing the bucket's structural integrity. Additionally, it is heat-treated for improved wear resistance in challenging conditions.

4. Grading Bucket

Known by various names, including dyking bucket and finishing bucket, the grading bucket is wide and shallow, ideal for leveling and profiling ground. Its low-profile shell is structured to maximize width without additional weight, preventing overload on the excavator.

Grading buckets are most effective with softer materials and aggregates, providing a smooth finish due to their flat edges and bottom. These buckets can also be used for tasks such as ditch cleaning, back-filling, and sloping. They frequently come equipped with a bolt-on blade for enhanced durability. Available in multiple widths, Rhinox mini grading buckets fit excavators from 0.75 to 25 tons, measuring between 30" to 84" wide.

5. Tilt Grading Bucket

The tilt grading bucket offers tilting capabilities, enhancing grading and profiling on angles. Equipped with a hydraulic hook-up, it tilts left or right, allowing for flexibility with complex forms, such as sloping landscapes or cleaning ditches. The Rhinox tilt grading bucket has a ram that allows for a 45-degree tilt in both directions and connects seamlessly to standard auxiliary hydraulics for quick setup.

6. V Bucket

The V ditching bucket features a triangular shape, designed for creating clean-sided, sloped drainage trenches. Commonly used for laying pipes and cables across large areas, these buckets are primarily manufactured for larger excavators due to the complexity of their trapezium shape. While Rhinox does not produce V buckets, notable manufacturers include Bucket Warehouse and Digbits.

7. Frost Bucket / Hardpan Bucket

Similar to the rock bucket, the frost or hardpan bucket includes a ripper tooth attachment on the back. Designed for additional digging capability, these teeth enhance penetration and help break up compacted ground, such as rocks and aggregates, where standard buckets may struggle. Unlike standard offerings, Rhinox does not manufacture frost buckets.

8. Micro Trenching Bucket

The micro trenching bucket, also known as a deep dig or fiber optic bucket, is narrower and deeper than other types. Initially designed for fiber optic cable installation, it also serves various applications like laying cables and pipes. Its primary benefit is the significant reduction in time required for digging and backfilling the trench, which also translates to cost savings on materials needed for reinstatement. Rhinox offers micro trenching buckets for mini diggers from 0.75 to 4 tons, with widths of 3", 4", 5", and 6", and depths of 400mm and 700mm (15" and 27").

9. Riddle Bucket

The riddle bucket, or skeleton bucket, features a slotted design, making it ideal for separating varying material sizes—such as removing bricks and roots from soil. Commonly used on building sites, these buckets enhance efficiency by sorting aggregates on-site, facilitating reuse or recycling rather than disposal as mixed aggregates. Rhinox produces riddle buckets in a wide range of sizes (24" to 60" wide) for excavators from 0.75 to 25 tons.

10. Rake Riddle Bucket

The rake riddle bucket seamlessly combines the functions of a land clearance rake and a riddle bucket. With a shallow design and slotted back along with narrow tines, this bucket allows for raking through materials like roots or brambles before sifting larger debris simultaneously. This dual functionality saves space and reduces costs associated with maintaining separate attachments. Rhinox rake riddle buckets are available for excavators ranging from 0.75 to 8 tons.

In conclusion, excavator buckets come in various shapes and sizes, each tailored to address specific construction, excavation, and landscaping challenges. From standard digging buckets to specialized attachments for rock excavation and trenching, these versatile tools are essential for maximizing efficiency and productivity on sites, while also minimizing costs related to repair or replacement. Understanding the unique features and applications of different excavator buckets ensures smooth and successful project execution.
