In this kind of work, you will not want to use the wrong tool. The reason is that every minute and effort you expend counts. If you don’t take note of the tools you are using, it can lead to many problems. For example, it can lead to a longer time in completing projects, workers frustration, and ultimately poor results. Here we introduce the excavator thumb bucket, a common landscape or construction attachment used in excavation.

Excavator Bucket Thumb

Excavators are always heavy-duty tools used in constructions, landscaping and other works. To work efficiently, the excavator needs some attachments. The most standard attachment used with it is the excavator bucket.

There are many types of Excavator buckets. Each one functions depending on its type. Therefore, they can be used in digging, trenching, scooping, or lifting materials. They are very useful but comes with a limitation. The limitation is it’s inability to handle materials well. This is where an excavator thumb comes in.

An Excavator thumb is another excavator add-on. Its design is like the human thumb. Therefore, it is ideal for grasping, clamping, securing, or even picking up materials. Its high gripping power also makes it ideal for such processes.

Due to its design, the excavator thumb complements the actions of the excavator bucket. Therefore, you can add it to the excavator bucket. This results into the excavator bucket thumb.

Types of Excavator Thumb Bucket
