Pitman and front casting protection plates (Pitman and Front Casting Protection Plate)— Jaw Crushers Wear part, position 07.
| Installation Position | On the feed-facing side of the pitman and lower front frame. Position 23 in the numbered diagram is the pitman protection plate; position 5 in the Sandvik section shows the front frame protection area. |
| Main Function | Shields the pitman and front frame castings from direct material flow and flying rock wear, helping reduce repairs to the main castings. |
| Replacement Frequency | Moderate wear exposure; assess remaining thickness, hole condition and exposure of the underlying casting when deciding on replacement. |
| Item | Details |
|---|---|
| Material Options | OEM-specified wear-resistant steel plate or castings |
| Typical Properties and Acceptance Criteria | Protection plates must be replaceable, fit securely and protect the underlying casting. Verify thickness, recessed holes, bolt locking, edge clearances and remaining wear allowance. Harder materials must still resist cracking at hole edges and brittle fracture from lump impact. |
| Principal Failure Mechanism | Sliding or three-body abrasion, localized impact and cracking around fastener holes |
