Guide to Excavator Attachments

Excavators are impressive, but not only because of their enormous size. They are instrumental, especially in the construction industry. Worksites have improved in efficiency and speed when completing projects, thanks to these powerful machines. Think about how long it would take to finish an excavating job if done manually.

But excavators are just the platform. The actual advantages lie in the specialised attachments that you can use for a wide variety of jobs. These attachments help dig, crush, flatten, and perform just about every task you want.

Each tool allows users to meet various challenges on their job sites, such as mines, quarries, and roads. These attachment tools are essential in performing each mechanised task in different applications. They are assembled with the excavator and its adaptation components. With the machine and the attachments together, they can form one whole unit that is incredibly productive.

This blog post gives you the details about excavator attachments that are commonly used in different worksites. You will find their description, as well as how they are utilised to make jobs easier.

 

1. Buckets

Heavy-duty buckets are used in large excavators.

Among the most used attachments for excavators are buckets. There are various types with their uses, including:

  • Sieve Buckets: They are suitable for removing hard materials, such as rocks. However, lighter substances like soil will stay put. This bucket is sort of a screening device that will help in sorting out different materials. A sieve bucket with a cutting edge can help with digging better. The bottom end strength is vital because it determines how much load the machine can carry.
  • Tilt Buckets: Almost all worksites have a tilt bucket. It is perhaps the most iconic of all excavator attachments. When looking for a tilt bucket, it should have two things – the correct shape and a sharp edge. With the proper form, you can maximise its efficiency in digging. Meanwhile, the sharp edge helps the bucket go deeper into the soil material. The hydraulic design for the bucket is perhaps the best feature you can find. It is more technologically advanced and allows the operator to gain better control when digging and trenching.
  • Crusher Buckets: During demolition, you need to get rid of unwanted material. You can use a crusher bucket for this task. It is also used in various jobs, such as excavation, recycling, mining, piping, and quarrying.

Buckets should have sturdy construction. Poor quality attachments can damage the excavator, while good quality ones can help you control the costs of your project.

 

2. Compaction Plates

Construction is messy, and sometimes, you need to flatten and smooth the surface after disturbing it. This is when you need a compaction plate. It is designed to neaten or tidy up the ground. You may know these plates as small tools that you can use by hand, but the bigger ones are used as excavator attachments.

When it comes to versatility, compaction plates will not let you down. Aside from flattening the area, they can also be used when working in a narrow trench. Let us say that you need to get into a large backfill, for example. But you are already using a compaction tool that is inclined vertically. You can turn to a compaction plate attached to an excavator to help you finish the job.

Try to look for a compaction plate that has multiple settings and can swivel its head 360 degrees. This way, you can ensure it will provide you with the maximum versatility for the job you require.

 

3. Compaction Wheels

Compaction wheels and plates are not the same. These wheels are utilised in worksites to reduce the size of soil or waste material. As the name suggests, it compacts or compresses the object. Some workers do the task on their own to save money. However, it only leads to slower performance, which is why using the machine is the better choice over manual work.

Using compaction wheels can help reduce costs because of their efficiency. They also work well whether you have a sloped or flat surface.

If you are on the market for this attachment, look for one that allows you to deal with different types of soil. Some compaction wheels are only valuable for granular soil or mud-like variety. Also, the wheels should be made from high-strength steel with quality roller bearings.

 

4. Grabs

The grab or the grappler is used to pick up and move heavy objects in the worksite.

Grabs are usually utilised for grabbing and moving massive rocks around the site. Most attachments require a great deal of precision to perform the task given to them. For example, it should provide excellent balance to avoid any struggle with the tool’s grip; otherwise, it can cause serious accidents.

Another requirement is that they should be robust and can resist wear. The device has fingers that can corrode or get worn out, increasing the risk of losing grip. Maintenance of this attachment is essential because the fingers should be replaced if faulty. Also, the pivot pins should remain rigid and sturdy to ensure a stronger hold.

 

5. Pulverisers

The pulveriser attachment can fit excavators ranging from 14T to 80T. It is versatile but primarily used to recycle waste after a demolition project. It can effectively crush concrete and separate rebars and scrap. One of the most significant advantages of using a pulveriser is that you can directly recycle waste material on the site. You, therefore, save a lot of time.

The attachment comes with cruciform teeth, which handles the tough job of crushing concrete. The versatility of this tool stops you from using other extensions or devices on-site, which also helps save money. For instance, instead of using a crusher bucket, you can simply use the pulveriser for crushing objects. At the same time, you can recycle the items that you require.

 

6. Rippers

The ripper attachment is a helpful addition to your excavator. It is pretty simple and often easy to use for any experienced operator. The ripper’s goal is quite simple: it will rip the ground up for you.

Rippers have a distinct appearance. You can recognise them easily because they look like a dinosaur’s sharp, curved tooth. They are also used when breaking into hard surfaces, such as frozen ground or paved areas. Worksites prefer rippers over other machine attachments because they operate quickly and almost without any noise. Another use of the ripper is to dig trees, taking them out from their roots.

 

7. Rock Saws

Rock saw attachment is used in demolition, construction, quarry, and mining.

Excavating tough material is a common occurrence in many worksites. You may be digging through thick rock. Perhaps you need to cut through roads or concrete. Rock saws can come in quite handy for these jobs.

This attachment is large and high-powered but still offers the operator good control. Only experienced operators should use this attachment because it requires accuracy. Typically, worksites utilise this tool to cut out a specific part of a building or rock. The point is to do it as precisely as possible to avoid harming the rest of the structure.

The attachment comes in different varieties and sizes of rock saw blades. Pick the best blade that your budget allows to get a more precise cut.

 

8. Trenchers

After gaining entry to the ground, worksites can use an excavator trencher. It often has a simple task, which is to dig trenches. You can indeed perform this job using other attachments, such as a bucket. However, the difference is that trenchers are much faster and better. One trencher can outperform two to four excavators when digging a trench in rocky ground.

If you are in a time crunch, trenchers will help you reduce the time needed to complete the digging process. Most construction jobs have strict deadlines. Get the job done faster with this attachment and save on costs as well.

Another benefit of using a trencher is that it can help you accomplish multiple steps with just one pass. For example, if you are cutting the trench, you can also produce the correct backfill. Using the trencher, you can deposit the backfill. Once installed, one of the crew may follow behind operating a dozer, which will move the material to the trench to serve as backfill.

 

Choosing the Right Excavator Attachment

The proper attachment can make the carrier easy to manoeuvre and operate. The choice, however, will depend on the type of excavator you have. For instance, if you have a crawling excavator, you should first check the front linkage and know the equipment’s dimensions. You should also consider the machine’s lifting power based on the dimension and movement geometry.

It is different from a compact excavator. The parts, which include the swing boom (also known as offset), side shift boom, and articulated knuckle boom, increase the total weight of the machine. They also change the front linkage geometry. Therefore, lighter attachments are a better choice. If you need help, you can talk to our knowledgeable staff for recommendations.
