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.
| Installation Position | Behind the lower part of the moving jaw, position 8 in the layout, between the upper and lower toggle seats. |
| Main Function | Transfers driving force to the moving jaw and, in some designs, serves as a sacrificial part under overload. |
| Replacement Frequency | Low replacement frequency; tramp metal, blockages, looseness or worn toggle seats can greatly shorten service life. |
| Item | Details |
|---|---|
| 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 |
