Excavator Attachments

Learn about essential excavator parts

An excavator is a serious piece of machinery—with a massive frame, a cab and a hulking arm and bucket, it's an imposing and incredibly useful tool for the job site. However, finding the right excavator attachment for the job can sometimes be tricky, particularly since most used excavators and mini excavators do not come with every available implement. In shopping for excavator attachments, it's important that potential buyers know what kind of tool they need and the kind of service they require from the seller. After all, while some sellers just market attachments, others can perform on-site fabrication and engineering, offering customized excavator parts based on the job at hand.

Excavator Buckets

There are several different types of excavator buckets available:

  • HP Buckets. Known as high-performance buckets, this class is designed for optimal production because of its heat-treated alloy steels, which are capable of intense digging and lifting thousands of pounds of material. HP buckets are ideal for basement contractors.
  • GP Buckets. General-purpose buckets are often smaller and lighter than HP buckets. They are meant for digging in light shale and rock.
  • HD Buckets. Heavy-duty buckets are designed for digging in thick rock and shale formations.
  • Thumbs. An excavator thumb can pivot on its own base plate or on the bucket pin.

Grapples

Excavator grapples are pincer-shaped tools designed to help crush stone, garbage, timber, construction waste and more. These attachments are typically employed to help demolish structures and obstacles. Their size can be adjusted for the excavator and the project involved.

Booms and Sticks

There are many different types of booms and sticks available, each with its own special function in the field. Most excavator attachment dealers offer products including tilt-head sticks (for tunnel restoration), stick and tilt units (for ditch digging and maintenance), jib and clam buckets (for hoisting dirt and waste), pin-on jibs (for jobs requiring extra extension), parallel-link stick extensions (for moderate extra reach) and straight stick extensions (for added height).

Stump Harvesters

Just as the name implies, stump harvesters are meant to extract large tree stumps with minimal effort. These pincer-shaped contraptions attach to a full-sized or mini excavator in place of a bucket and can literally grab and pull a stump right out of the ground.
