Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Pitman and front casting protection plates
Shields the pitman and front frame castings from direct material flow and flying rock wear, helping reduce repairs to the main castings.
Pitman and front casting protection plates (Pitman and Front Casting Protection Plate)— Jaw Crushers Wear part, position 07.
Location and Function
| 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 |
Information Required for RFQ
- Equipment manufacturer, machine model, serial number, model details and latest drawing revision;
- Part dimensions, unit weight, key tolerances, assembly and fastening method;
- Current material, chemical composition, heat treatment, hardness and mechanical property reports;
- Processed material, maximum particle size, hardness/abrasiveness, moisture and tramp material records;
- Speed, load, temperature, pressure, process medium chemistry and continuous operating time;
- Failure photographs, wear measurements, crack/fracture locations and current service life;
Materials and values are for preliminary engineering selection. Final chemical composition, heat treatment, hardness and dimensional tolerances must follow the OEM drawings and technical agreement.
