Parts
A digger bucket, also known as an excavator bucket, is a complex piece of equipment with several key parts that work together to perform various digging and material handling tasks. The main parts of a digger bucket include:
| Sr.No. | Component Key | Grades Available |
|---|---|---|
| 1 | Beam | Hardox 400/450 |
| 2 | Attachment | Hardox 400 |
| 3 | Shell | Hardox 400/450 |
| 4 | Wear bar | Hardox 500 |
| 5 | Side sheet | Hardox 400/450/500 |
| 6 | Cheek plate | Hardox 500 |
| 7 | Side corner | Hardox 500 |
| 8 | Side cutter | Hardox 400/450 |
| 9 | Cutting edge | Hardox 400/450/500 |
Base Plate
The base plate forms the bottom part of the bucket and provides structural support. It connects to the excavator arm and holds the other components in place.
Side Plates
The side plates are vertical panels on either side of the base plate. They help contain the material being excavated and provide additional structural integrity to the bucket.
Cutting Edge
The cutting edge is a hardened steel edge welded to the front of the bucket. It comes into direct contact with the ground and materials, allowing the bucket to cut through soil, rocks, and other materials during excavation.
Teeth
The teeth are pointed, replaceable tips attached to the cutting edge. They assist in breaking up hard ground and materials, making digging more efficient.
Adapters
Adapters are the interface between the bucket teeth and the cutting edge. They allow for easy replacement of the teeth when they wear out without having to replace the entire cutting edge.
TLip Shrouds (Wear Plates)
Lip shrouds, also known as wear plates, are additional protective plates that cover the area around the bucket's cutting edge. They help prevent wear and damage to the bucket's structure during digging.
Corner Heel Shrouds
These shrouds are installed at the rear corners of the bucket and help protect the bucket from excessive wear and damage at these critical points.
Bucket Ears (Lug Ears)
The bucket ears are the mounting points on the sides of the bucket that connect to the excavator arm using pins. They allow the bucket to pivot and move during operation.
Bucket Linkage
The linkage mechanism enables the bucket to be controlled and moved by the excavator's hydraulic system. The bucket linkage consists of cylinders and hydraulic hoses that control the bucket's movement, such as opening, closing, and tilting.
Wear Strips
Wear strips are additional reinforcements usually welded to the inside surface of the bucket to increase its longevity and resistance to abrasion and wear.
These are the primary parts of a typical digger bucket. However, it's essential to note that there can be variations in bucket design and features depending on the specific application and the manufacturer. Different types of buckets, such as digging buckets, grading buckets, rock buckets, and ditching buckets, may have unique configurations to optimize their performance for specific tasks.
