Digger buckets are one of the most important accessories to choose after selecting your excavator. If you are considering different bucket styles or even bucket functions, then hopefully you have already decided on the perfect excavator for the job.
Whether you have selected a small micro digger or a 20-ton excavator, we all won’t get far, without marrying them up with the right style bucket. So, where do you start? What’s available and what is going to be best for the work you have planned?
In this article, we will take you through the most common types of digger bucket you’ll find on the market. As well as, their roles in helping make your job as efficient as possible.
A digger bucket is a removable attachment from a diggers arm. These buckets are designed to puncture/scrape and collect earth, which then can be moved to an alternative location. Digger buckets are controlled by the machine’s operator in its cabin.
Different digger buckets are used to assist the operator depending on the type of work that is being undertaken. The bucket is attached to the arm of the digger via a hitch. The hitch is the important component that connects a bucket to the arm of an excavator.
Depending on the type of hitch your excavator has, will depend on how much manual labour is involved when the time comes to change your diggers bucket.
Choosing the correct bucket for your project will make a huge difference in the excavator’s efficiency. However, you need to consider the application and material you are working with. Ideally, finding the largest bucket that is suitable for the material, conditions and application.
However, it is not always a case of just selecting the biggest bucket possible. You also need to consider the density of the ground. The harder and more compact the ground, the smaller your puncture will need to be to penetrate the surface. Therefore, using a bucket with a smaller surface area, will enable you to penetrate more compact earth.
Although, for some tasks, consider is a specialised bucket. Specialised buckets can be ideal if you are using a digger for a particular job. For example, an 18-inch trenching bucket to create footing holes.
Digger buckets are available in different shapes and sizes. However, each individual design can be used to be tailored to the job at hand. The most common buckets that are used with an excavator are as follows:
Digging buckets are multipurpose attachments that come as standard with all diggers on hire. Some are equipped with blunt short teeth that can be used to penetrate the surface when lowered into the ground. These multi-purpose attachments are ideal if you are working with:
Trenching buckets are designed specifically for trench excavation. They work extremely well for navigating small space areas for things such as piping, ducting and drain digging. The buckets design is narrow and fitted with a sharp flat blade to penetrate through dense, compact ground materials. As a result, operators can be very precise with their work. Trenching buckets are also available on all excavators in a range of different sizes to suit.
Trenching BucketGrading buckets are a popular choice for most work with an excavator. This is because their design offers a smooth and wide cutting edge that work best with all soft materials and soils. Grading buckets are popular for loading and unloading materials, grading, levelling and backfilling holes. These digger buckets are favoured by landscapers, road constructors, construction sites during the export and import of materials and utility work.
Grading BucketHeavy-duty digger buckets are designed for exactly what you would expect. Constructed from high strength, abrasive-resistant steel, these buckets are used in the toughest of conditions. Because of this they are commonly found in quarries, allowing operators to extract the densest of materials. Some examples of the type of rock you would expect to use a heavy-duty bucket on would be:
Besides digging, trenching, grading and heavy-duty digger buckets, innovative excavator attachments are available on the market to assist operators. These types of buckets have been designed for specific tasks:
V Bucket – For digging V-shaped trenches
Rock bucket- Screeding soil to remove debris
Riddle bucket- A digging bucket that allows small soil particles to pass through.
Hard pan bucket- Similar to a rock bucket but has ripper teeth on each side of the bucket, designed to loosen soil during use.
Use these sizes as a guide to help you understand the dimensions of buckets that suit different excavator sizes:
Micro digger bucket sizes (mm) 230/300/450/600/Grade
Mini Digger 1.5 T (mm) 150/230/300/450/600/1000/Grade
3T Digger (mm) 225/300/450/600/1200/Grade
5T Digger (mm) 300/450/600/750mm/Grade
8T Digger (mm) 300/450/600/900/Grade
14T Digger (mm) 450/600/900/1200mm/Grade
20T Digger (mm) 600/900/1500/Grade 2200
Buckets are operated from the cabin of the digger/excavator. By using the right-hand side joystick, users can pull left towards themselves to cradle the bucket, and right to extend. When curling the bucket into the ground, the machine will gather the earth below until it reaches full capacity. After extraction, you can extend the bucket arm to unload it. This is done by pushing and holding the right joystick right until the bucket completely empties. (See diagram)
