10 Different Types of Excavator Buckets


The construction industry is constantly growing and changing to keep up with the needs and demands of the users and operators in it. Where having the correct equipment for the job is essential. So, choosing the appropriate excavator bucket for your machines are necessary to efficiently tackle the specifications of the job and the type of material you are handling. There are now a huge selection of different types of buckets, so you might not know where to start if you're new or just looking to try something else. We have complied a list of 10 Different types of Excavator Buckets and what we believe are their best uses.

If you want to learn more, please visit our website GRS.

1. Digging Bucket


Also known as a general purpose excavator bucket, the digging bucket is the attachment you will most likely recognise. Digging buckets are the most common bucket provided with mini diggers and excavators when buying or hiring. It's primary use is what the name suggests - bulk digging through soil and rubble in construction, landscaping or groundworks environments.

The digging bucket is most commonly seen with fitted with teeth to help penetrate tougher, more compact ground. The teeth break through the material allowing you to scrape it into the bucket to be moved or removed. They're also becoming popular to be fitted with a blade for creating a flat bottom to your trench or to be used around utilities. The general purpose digging bucket usually comes in a large variety of widths to best suit the job at hand. For example, Rhinox mini digging buckets are available for 0.75 to 25 ton excavators, in 6", 9", 12", 18" and 24" to best suit the application, whether that be digging a small ditch or clearing a larger area.

2. Rock Bucket


Although a durable bucket, the standard digging bucket may not always be the most suitable bucket for your digging job. The rock bucket is a heavy duty version of the standard digging bucket. Rock buckets are reinforced with much stronger and thicker wear plates to add 'bulk' to the bucket and are fitted with sharper teeth. These modifications reinforce the bucket for use in much harsher conditions and help penetrate solid materials. A popular use is continuous breaking up of rocks and extremely abrasive, compact materials, like in quarries. Rock buckets are currently not available at Rhinox.

3. Utility Bucket


The utility bucket is a modification of the standard digging bucket, featuring the addition of the Uni-tusk - a rounded edge, bolt-on blade. The Uni-tusk is a Rhinox invention and was initially created to help protect utility workers when digging near utilities as it deflects cables away from the bucket. The unique Uni-tusk blade system has been manufactured as a bolt-on edge option to replace teeth or standard bolt-on blade options. As well as, the improved safety for utility works, the rounded, cast steel blade locks the side plates and lip plate in place, to increase the structural integrity of your bucket. It is also heat treated to 550 HB to further maximise the wear strength for continuous digging in harsh conditions.

4. Grading Bucket


The grading bucket is known by a wide variety of names, including: dyking bucket, finishing bucket or ditching bucket. The grading bucket is a wide, shallow bucket used for levelling and profiling the ground. The low profile shell design was designed to increase the width of the bucket without increasing the weight, as not to overload your excavator.

As mentioned, these buckets are best used for profiling, particularly softer materials and aggregates. The wider shell enables you to cover a wider distance in one motion. These buckets create a smooth finish to the material you're profiling due to the flat edge of the bucket, as well as the flat bottom. But they can also be used for a variety of other tasks such as: cleaning ditches, loading material, back-filling and sloping. The grading bucket is commonly fitted with a bolt-on blade to strengthen the lip plate and provide additional resistance against wear to prolong the life of your bucket. Grading buckets are available in a wide variety of widths to suit your excavator size. For example, Rhinox mini grading buckets are available for 0.75 to 25 ton excavators, in 30" to 84" wide.

5. Tilt Grading Bucket


The tilt grading bucket is exactly what the name suggests, it is a grading bucket that has the ability to tilt. A tilting bucket is the solution to grading and profiling on an angle. They're manufactured with a hydraulic hook up to allow them to tilt from left to right, providing greater flexibility when working on more complex forms and shapes, such as levelling slopes, cleaning ditches and maintaining sloped landscapes. The Rhinox tilt grading bucket is manufactured with 1 ram to allow you to tilt 45 degrees in both directions and plugs straight into your standard auxiliary or hammer hydraulics making it quick and easy to attach them ready to use.

6. V Bucket


The V ditching bucket is a triangular shaped bucket, designed to form clean sided, sloped drainage trenches. These V shaped dyking buckets are also commonly used for digging V shaped trenches used for laying pipes and cables across large plots of land. These buckets are usually manufactured for larger excavators due to the complex design required to create the trapezium shape. Currently, Rhinox do not manufacture v buckets but some of the popular manufacturers of this bucket on the market include Bucket Warehouse and Digbits.

7. Frost Bucket / Hardpan Bucket


A frost bucket or hardpan bucket looks and performs similarly to a rock bucket but has a bonus feature...a ripper tooth style attachment fitted to the reverse of the bucket. Depending on the manufacturers design, they might fit multiple of these ripper teeth features, with the purpose of these to further increase the digging ability. They provide additional penetration to help break up extremely compacted grounds, where your standard digging or rock bucket can't quite cut it - helping to loosen rocks and other aggregates as the bucket curls round. Rhinox do not manufacture frost buckets.

8. Micro Trenching Bucket


The micro trenching bucket, also known as a deep dig or fibre optic bucket, is a deeper, narrower bucket than any other. The micro trenching bucket was initially designed for digging narrow trenches for the installation of fibre optic cables but is now used for a variety of applications, such as laying standard cables, pipes and irrigation. The main benefit of the micro trenching bucket is the time spent digging, backfilling and remediating surfaces. The amount of time taken to dig out the initial trench is drastically reduced alongside a reduction in the amount of time spent backfilling the area you have dug out. You can also save large amounts of money on materials usually required to reinstate the surface to it's initial condition, such as retarmacking a public footpath. Rhinox micro trenching buckets are available for 0.75 to 4 ton mini diggers, in 3", 4", 5" and 6" widths at depths of 400mm and 700mm (15" and 27").

9. Riddle Bucket


The riddle bucket is also referred to as the skeleton bucket due to its design or a shaker bucket due to the action required to use it. Riddle buckets are manufactured with a slotted back and used for separating different sizes of material, for example removing bricks and roots from soil. They are primarily used on building sites to remove larger aggregates from the ground to be reused or recycled. Most often, it's more cost effective to separate the aggregates on-site and arrange for their collection or repurposing, rather than disposing of them as mixed aggregates. Rhinox riddle buckets are manufactured using a similar design to our standard digging buckets which allows us to produce a variety of sizes, from 24" to 60" wide, to suit 0.75 to 25 ton excavators.

10. Rake Riddle Bucket


The rake riddle bucket is a combination of your standard land clearance rake and a riddle bucket. Also known as the rake bucket, the rake riddle bucket is a shallow bucket with a slotted back and narrow tines along the front edge. As the name suggest, the rake riddle bucket allows you to rake through materials in the ground like tree roots or brambles and then riddle the material of bricks and larger rocks in one movement. The rake riddle bucket is designed to save you money as you not only save space required to store two separate excavator attachments, you also save money on purchasing and maintaining two separate attachments. Rhinox rake riddles buckets are currently available for 0.75 to 8 ton excavators.

In conclusion, excavator buckets come in various shapes and sizes, each tailored to meet specific construction, excavation and landscaping challenges. From standard digging buckets to specialised attachments for rock excavation, grading and trenching, these versatile tools are essential for maximising efficiency and productivity on sites, as well as saving you money on repairing or replacing damaged buckets. Understanding the unique features and applications of different types of excavator buckets ensures smooth and successful project execution.

Types of Excavator Buckets

The right excavator bucket is key to making sure your excavator can accurately and efficiently complete a task. You have a wide variety to consider, and you might not know where to start. This guide will walk you through the different types of excavator buckets and help you understand which one is best for your job.

Here are the excavator bucket types you have to choose from and the jobs they most commonly do:

Jump To Sections:

1. GENERAL PURPOSE BUCKETS

General purpose excavator buckets are versatile, making them a great choice if your worksite is not focused on one specific task. Because you can use them for such a wide variety of tasks, they are the bucket of choice when a client does not specify the type of bucket they want on their excavator.

A general purpose excavator bucket is characterized by short, blunt teeth that are available in a number of sizes.

2. GRADING BUCKETS

Grading excavator buckets offer smooth edges, flat cutting edges and wide builds. Some of their more unique characteristics include lift eyes, reversible bolt-on cutting edges and weld-on side cutters. These buckets also have a lot of versatility, specifically for loading a variety of materials.

Grading buckets can also be called ditching or clean-up buckets. You can use them in many contexts, including ditch maintenance, slope shaping, landscaping, utility work and road construction. Grading buckets traditionally have a straight edge, no teeth and a flat surface. The flat surface makes it easy to smooth out various surfaces.

3. HEAVY-DUTY BUCKETS

Heavy-duty buckets are sometimes called severe-duty buckets and are made to be incredibly durable. Abrasion-resistant, high-strength steel is commonly used to make these buckets. You will often find contractors using them in rock quarries or other areas where materials need to be dug or loaded out of a strong area.

They are also meant to be able to load heavy material with as few passes as possible. Some include a straight edge or spade nose so they can accept different types of teeth and excavate the right materials. Heavy-duty buckets often haul hard-packed clay, stone, ripped basalt, gravel, blasted rock, sharp rock, high-silica sand, gravel, shale and shot granite.

4. TRENCHING BUCKETS

A trenching excavator bucket is meant for working in small spaces, such as narrow cable trenches, drains and pipes. Trenching buckets are often used for digging trenches. They are unique in that they can deepen a trench quickly.

When working on digging a trench through an area that has a lot of obstacles, trenching buckets make it easy to be precise and avoid pipes and other obstructions. You can choose different size buckets based on the size of the trench you are trying to build. Trenching buckets are also a great tool for back-filling ground that is not too hard.

5. ANGLE TILT BUCKETS

Angle tilt excavator buckets are similar to grading buckets but can rotate 45 degrees in both directions. That makes them a great tool for creating precise slopes. They also make it possible for excavators to stay stationary while still having the flexibility to mold and shape the land.

Because you do not need to move the entire excavator very often, you will save time on projects that involve heavy-duty construction. Angle tilt buckets can be used for sloping, grading, finishing, trenching, ditch cleaning, leveling and many other applications.

CHOOSING BETWEEN EXCAVATOR BUCKET SIZES

When choosing the right excavator bucket, finding the right size is an essential part of the process. You must first determine the intended use of the bucket.

Say you are digging a trench. You will need to choose a bucket that is smaller or the same width as the trench you are going to build. If you are using the excavator bucket to move heavy materials, make sure you choose a bucket that is sturdy and large.

The size of the bucket you choose will also depend on the size of your excavator and the type of bucket you want to use. To increase efficiency, use an excavator and choose a type of bucket that will allow you to have the largest bucket you can to still accurately complete your project.

There are sizing rules you can follow to help you estimate in general what size bucket you need for your job and with your excavator:

  • 0.75-ton excavators and below: This size of excavator typically has a bucket that is between 6 and 24 inches wide. If you have a grading bucket with an excavator that is this weight, you can go up to a 30-inch bucket.
  • Between 1 and 1.9 tons: The bucket should be between 6 and 24 inches. Grading buckets on this excavator can be between 36 and 39 inches.
  • Between 2 and 3.5 tons: These buckets can have a width of between 9 and 30 inches with grading buckets being 48 inches.
  • 4 tons: Buckets on 4-ton excavators can be between 12 and 36 inches wide, while grading buckets can be 60 inches wide.
  • Between 5 and 8 tons: The buckets on these excavators are between 12 and 36 inches. Grading buckets are 60 inches wide for 5- or 6-ton machines and between 60 and 72 inches wide for 7- or 8-ton machines.
  • Between 10 and 15 tons: Buckets on these excavators are between 18 and 48 inches wide, while grading buckets are 72 inches wide.
  • Between 19 and 25 tons: These buckets are between 18 and 60 inches wide. Grading buckets on these excavators are 84 inches wide.
