Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Toggle Plates
Transfers driving force to the moving jaw and, in some designs, serves as a sacrificial part under overload.
Toggle Plates (Toggle Plate)— Jaw Crushers Wear part, position 08.
Location and Function
| Material Options | Cast steel or quenched and tempered alloy steel; material, cross-section and protective failure load must follow the OEM design |
| Typical Properties and Acceptance Criteria | The 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 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.
