Jaw Crushers

For primary stage medium to high capacity hard rock crushing or demolition applications

RockSledger jaw crushers feature massive, stress relieved, single plate walls with deep and substantial external side stiffeners and a high quality forged steel eccentric shaft.

The shaft is fully machined and has a ground finish on all bearing contact surfaces to increase resistance to shock loadings resulting in longer machine life.

RockSizer primary stage jaw crushers feature the upthrust toggle action which is also common to the StoneSizer range. Developed by Parker, this gives a slight downward movement to the swing jaw that promotes a forced feed and therefore increased output while at the same time minimising any rubbing action resulting in a well shaped product and reduced and even wear on the crushing jaws.

The purpose-built RockRanger is suitable for both quarry and demolition applications and incorporates a vibrating feeder with replaceable grizzly section and the option of a Vibrating Grizzly Screen.

The RockRanger has a wide discharge conveyor with good clearance under the crusher. Installation is rapid and easy to set up. The feed hopper is an externally reinforced heavy-duty steel plate hopper to stand up to the toughest of jobs.

The wheeled RockRanger is a high-capacity, extremely mobile crushing unit suitable for demolition, quarry or gravel feed application.

Mounted on a robust, semi-trailer chassis, a Parker RockSizer or RockSledger primary jaw is combined with a matched, high strength feeder/grizzly and integral product conveyor to give owners portable primary crushing at its best.

A fully mobile primary crushing plant complete with a Parker Rocksizer or RockSledger single toggle Jaw crusher, built around a strong straight beam chassis with standard supports for feed section, crusher, power unit and conveyor frame. The chassis is complete with access/maintenance platforms to the crusher and power unit and a main operator platform overlooks all stages of operation.
