Back faces of all jaws are machine ground to provide firm support. Two piece reversible jaws are provided on our larger crushers to allow maximum jaw life. The jaw-faces are fully reversible. Replaceable jaw-face backing plates are provided to protect the machined jaw-face locations and the jawholder guard, provides protection for the jawholder bearing housing.
The toggle rolls across the flat pressure face of the toggle seat. No rubbing or scuffing takes place and friction is kept to a minimum. This type of toggle system has the following advantages over the socket end type toggle and seat:
1.No lubrication whatsoever is required
2.The system can handle far greater crushing pressures.
3.The life factor of toggle and seats is many times greater.
Can be removed from the frame as an assembly. The jaw-holder is a robust box construction with a fully machined face to support the moving jaw.
