Jaw Crusher Toggle Plate

Jaw Crusher Toggle Plates are designed to shear protecting crusher components if noncrushable object is introduced to crusher.

Toggle plate function

The bottom of the pitman is supported by a reflex-curved piece of metal called the toggle plate. It serves the purpose of allowing the bottom of the pitman to move up and down with the motion of the eccentric shaft as well as serve as a safety mechanism for the entire jaw. If a piece of non-crushable material such as a steel loader tooth enter the jaw and be larger than the closed side setting it can't be crushed nor pass through the jaw. In this case, the toggle plate will crush and prevent further damage.
