The excavator bucket is a structural assembly consisting of tooth‑base plates, bottom plates, side plates, wall plates, lug plates, back plates, ear plates, ear sleeves, bucket teeth, tooth adapters, wear plates and corner protectors. Welding is the critical manufacturing procedure; welding quality directly determines structural strength and service life of the bucket. Below is an introduction to dimension standards for backhoe buckets.

Bucket models are defined by bucket capacity. Different capacities bring distinct overall dimensions. Bucket width, height and depth are key specifications for bucket selection.

Buckets can be classified by material and function. Material‑oriented buckets are widely adopted for various working conditions, including river dredging, hard‑soil & soft‑rock operation, hard‑rock excavation. They feature good corrosion resistance and bending‑resistance performance.

According to application scenarios, buckets fall into standard buckets, heavy‑duty buckets and rock buckets. Rock buckets are in great demand for trench digging, municipal cleaning, agriculture and forestry work.

As the core working attachment of excavators, buckets are frequently used on construction sites with high performance requirements.

Ⅰ. Dimension Standards for Excavator Buckets

Bucket model is calibrated based on bucket capacity, which determines overall dimensions. Bucket width, height and depth serve as major judging indicators.

Classified by material and function, material‑type buckets can adapt to river cleaning, hard‑soil, soft‑rock and hard‑rock conditions with reliable corrosion resistance and bending strength.

There are standard, heavy‑duty and rock buckets for different projects, widely used in trenching, municipal maintenance, agriculture‑forestry construction.

Being a key working attachment for excavators, buckets are in large demand during construction with strict performance requirements.
