Toggle Plate is a simple & low-cost but very important part of jaw crusher.
It is usually made of cast iron or high manganese steel, and it is used to hold the lower part of the jaw in position, it also serves as a safety mechanism for the entire jaw.
If something that the jaw crusher cannot crush gets into the crushing chamber accidentally and it cannot pass through the jaw, the toggle plate will crush and prevent the whole machine from further damage.
