Double-toggle jaw crushers. In a double-toggle jaw crusher, the moving crusher jaw is driven by the eccentric shaft that moves the front and rear toggles up and down. Each shaft revolution causes the moving crusher jaw to close at the downstroke and open up during the upstroke. The toggle is kept in place by spring-loaded tension rod.
