An Excavator's Bucket Reaches for a Boulder
A bucket is a specialized container used to excavate and load bulk material. It is usually attached to the end of a boom and connected to an excavating machine. The material is scooped at the front and held inside the bucket until it is disposed of.

Since there are many different materials to be excavated, there are different buckets to match each material.

[edit] Types

(Names may vary depending on manufacturer)

[edit] General Purpose/ Standard Duty

Used in soil where shock loading and abrasion is not expected. They are equipped with teeth and corner bits to aid in penetration of the material and thereby extend the life of the bucket.

[edit] General Purpose/ Heavy-duty

Generally excavate the same type of material as the standard duty, but are stronger and more wear resistant. They are equipped with heavier teeth and corner bits.

[edit] Extreme Service

Used to excavate rock, when shock loading and abrasion is expected. They have a strong basic structure and are equipped with the strongest teeth and corner bits.

[edit] Clean-up/ Loose Material

Used in granular and soft material. They are extra wide to supply extra capacity, but are not equipped with teeth.

[edit] Clean-up/ Heavy-duty

Used in loose material. They are also used to spread or smooth coarse materials that have already been excavated. They are extra wide to supply extra capacity.

[edit] PowerTwist

Used for ditch cleaning and profiling slopes. They can tilt 45 degrees left or right.

[edit] Clamshell

Used to bale loose material. They open and close like a mouth on the material to pick it up. They can be equipped with teeth.

[edit] PowerClam

Operate on the same concept of the generic clamshell, but can also grip, turn, pull and curl. They provide more variation to an otherwise basic tool.

[edit] Vee Bottom

Used to excavate hard material like frost or shale. They are equipped with large, strong teeth of varying lengths. They are designed to penetrate the material with one tooth, and as the cut deepens, the additional teeth cut in like rippers.

[edit] Trapezoidal

Used for deep wide trenches where a narrow bottom bucket is required to conserve pipe bedding materials. They consist of a tapered design to yield a specific trench bottom width and wall slope.

[edit] Heavy-duty/ Extreme Service

Used for heavy duty excavating. They are equipped with reversible teeth and wear plates.
