Wear Plate
Replaceable steel plate designed to absorb abrasion and protect the main structure of an attachment.
Wear plates are sacrificial steel components bolted or welded to high-wear areas of excavator attachments. They extend the operational life of buckets, crushers, and other tools by absorbing abrasion that would otherwise damage the main structure.
Types of wear plates:
- Floor wear strips: Protect bucket floor during loading
- Side wear plates: Protect bucket sidewalls
- Heel plates: Protect the rear cutting edge area
- Cheek plates: Protect areas near teeth adapters
Material choices:
- Standard structural steel (S355) for light applications
- Hardox® 400 for general wear resistance
- Hardox® 450/500 for quarry and demolition
Wear plates should be inspected regularly and replaced before wear penetrates to the main structure. On Sieruta attachments, wear bars and wear plates are mostly options. A few models have them as standard, for example the HB500 wear bars under the GRB grading beam.
