Attachments and Wear Parts
Attachments help you get more work done with your excavator. You use different attachments for digging, lifting, or breaking. These parts face heavy loads and tough ground every day. Good maintenance keeps your attachments strong and safe.
Buckets, Teeth, and Cutting Edges
Buckets, teeth, and cutting edges do most of the hard work. You need to check these attachments often for cracks, chips, or worn spots. If you see missing teeth or thin edges, replace them right away. Worn parts make your excavator attachments less effective and can slow down your job.
The material in bucket teeth and cutting edges changes how long they last. Carbon steel works well for many jobs, but it may not hold up in rocky ground. Boron steel lasts longer and handles tough digging. Chromium and nickel alloys resist rust, so they work well in wet or harsh places. Carbide-embedded edges give the best wear resistance when you dig in rock. Each material has its own strengths and weaknesses. Some materials get stronger as you use them, a process called work hardening. This helps them last longer under tough conditions.
Material Type | Wear Mechanism | Work Hardening Influence |
|---|---|---|
Martensitic Steels | Abrasion, Impact-Abrasion | Significant effect on wear resistance |
Commercial 500HB Steels | Surface and Subsurface Shear Bands | Clear differences in wear rates observed |
