C-12 CRUSHER
TOGGLE PLATE REMOVAL / REPLACEMENT
To protect the crusher from the excessive loads generated by un-crushable objects, the Jawstock is fitted with overload
protection device - "Toggle Plate". When the permissible loads are exceeded, the Toggle Plate will collapse from elastic
buckling and the crusher will automatically shut down, providing a degree of protection to valuable machine components.
When this happens, then clear any blockages from the machine and fit the replacement toggle in the following way.
