Bucket Anatomy and Functions
Bucket Shell
The bucket shell forms the main body of the bucket. You will notice that this part gives the bucket its shape and strength. The shell holds all other parts together. When you use heavy duty buckets, the shell must handle strong forces from digging and lifting. Trenching buckets have a narrow shell to dig deep, clean trenches. The shell’s design affects how much material you can move and how well the bucket fits your excavator.
Teeth and Adapters
Teeth sit at the front edge of the bucket. They help you break into hard soil, clay, or rock. Adapters connect the teeth to the bucket, making it easy to replace worn teeth. Most teeth and adapters use high-quality alloy steel. This steel contains elements like carbon, silicon, manganese, chromium, and aluminum. To make them last longer, manufacturers add microelements such as molybdenum and nickel. The surface hardness usually ranges from HRC46 to HRC52. The process uses lost wax casting and heat treatment for extra strength and wear resistance.
Material Element | Purpose |
|---|---|
Carbon (C) | Increases hardness |
Chromium (Cr) | Improves wear resistance |
Nickel (Ni) | Adds toughness |
Tip: Always check the teeth and adapters for wear. Replacing them on time keeps your bucket working well.
Side Cutters and Cutting Edge
Side cutters attach to the sides of the bucket. They protect the shell and help you cut through tough ground. You can find straight, curved, or serrated side cutters. Each type helps you with different jobs, like trenching or shaping edges. The cutting edge runs along the bottom front of the bucket. It uses hardened steel with a hardness of 400-450 BHN and a thickness between 12-24 mm. This edge lets you dig into the ground easily and protects the bucket from damage. Together, side cutters and the cutting edge improve your work quality and make your bucket last longer.
Wear Plates
Wear plates cover the parts of the bucket that face the most friction. You will see these plates on the bottom and sides of heavy duty buckets. They protect the shell from wearing out too fast. If you use trenching buckets, wear plates help the bucket keep its shape even after many hours of digging. You should check wear plates often and replace them when they get thin.
Pins and Bushings
Pins connect the bucket to the excavator’s arm. Bushings fit around the pins and let them move smoothly. These parts help you attach or remove the bucket quickly. If pins or bushings wear out, the bucket may not move correctly. You should grease these parts often to keep your bucket working safely.
Note: Keeping pins and bushings in good shape helps you avoid costly repairs and keeps your excavator running smoothly.
