Toggle Plates

Transfers driving force to the moving jaw and, in some designs, serves as a sacrificial part under overload.

Toggle Plates

Toggle Plates (Toggle Plate)— Jaw Crushers Wear part, position 08.

Installation and Function

Installation PositionBehind the lower part of the moving jaw, position 8 in the layout, between the upper and lower toggle seats.
Main FunctionTransfers driving force to the moving jaw and, in some designs, serves as a sacrificial part under overload.
Replacement FrequencyLow replacement frequency; tramp metal, blockages, looseness or worn toggle seats can greatly shorten service life.

Materials and Mechanical Properties

ItemDetails
Material OptionsCast steel or quenched and tempered alloy steel; material, cross-section and protective failure load must follow the OEM design
Typical Properties and Acceptance CriteriaThe toggle plate transmits force and may also provide mechanical overload protection. Preserve the OEM-specified buckling, fracture or release behaviour. Acceptance checks focus on material traceability, cross-sectional dimensions, surface and internal defects, and contact faces at both ends. Increasing strength simply to extend toggle plate life may transfer an overload to the frame, eccentric shaft or bearings.
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.
