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 plates (Pitman and Front Casting Protection Plate)— Jaw Crushers Wear part, position 07.

Installation and Function

Installation PositionOn 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 FunctionShields the pitman and front frame castings from direct material flow and flying rock wear, helping reduce repairs to the main castings.
Replacement FrequencyModerate wear exposure; assess remaining thickness, hole condition and exposure of the underlying casting when deciding on replacement.

Materials and Mechanical Properties

ItemDetails
Material OptionsOEM-specified wear-resistant steel plate or castings
Typical Properties and Acceptance CriteriaProtection 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 MechanismSliding or three-body abrasion, localized impact and cracking around fastener holes

Material and Design Considerations

  • Identify material hardness, particle size, abrasiveness, moisture, temperature, pH, impact and tramp material;
  • High hardness does not replace core toughness, fatigue strength, corrosion resistance or high-temperature performance;
  • For composite, hardfaced, ceramic and elastomer designs, assess substrate bonding, edge protection, fastening and maintainability;
  • For parts that mate with shafts, gears, seals, roll surfaces or housings, control fits, tolerances, surface finish and assembly clearances together;
  • Assess material upgrades using cumulative throughput, dimensional wear, failure modes, product quality and downtime costs.

Required Ordering / RFQ Information

  • Equipment manufacturer, machine model, serial number, part number 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.
