Terex® Cedarapids JS Series Jaws

Terex® Cedarapids jaw crushers have always been known for durable construction, high productivity and a greater value for investment. And now, the new JS Series jaw crushers are built even more rugged and are easier to use. We have taken our jaw crushers to a new level of reliability and convenience.

The new quick-change jaw die system and quick-adjust hydraulic shim system provide more uptime. Combine these features with our well-known durability and you have a crusher that keeps you up and running.

Reliability, quality, capacity, and ease of use-the new Terex® Cedarapids JS Series jaw crushers are designed to help you be more profitable. That's what it's all about.
