Maintenance Recommendations
Monitor jaw plate wear pattern for uneven wear indication. Replace toggle plates immediately if deformation detected. Check pliman adjustment monthly.

Pennsylvania Crusher
Jaw Crushers (Double Toggle)
Pennsylvania double-toggle jaw crushers are engineered for primary crushing of coal, salt and minerals. The double-toggle mechanism provides a more uniform crushing action and better nip angle compared to single-toggle designs. The heavy-duty frame and pitman design ensures reliable operation in demanding applications. Anranst provides jaw plates in ASTM A128 Grade B-2, toggle plates in ASTM A148/148M, and thrust plates in ASTM A27/27M.
