A swing jaw of a jaw crusher includes a cast swing jaw frame and a retention seat for a toggle seat having a first retention seat part. The retention seat includes a detachable retention plate that is configured to couple to the first retention seat part so as to clamp a toggle seat therebetween in a wedged clamping arrangement. The first retention seat part is usually integrally cast with the cast swing jaw frame. The retention seat upon assembly has opposed sidewalls that diverge towards a rear wall of the retention seat to wedge the toggle seat in position in the assembled retention seat. Generally, the first retention seat part has a first sidewall and a rear wall of the retention seat, the detachable retention plate having a second sidewall of the retention seat.

A jaw crusher service tool for supporting an item during service of a jaw crusher, which has a fixed jaw and a movable jaw mounted in a crusher frame that define a crushing chamber for material to be crushed, is provided. The service tool includes a support frame for supporting the item and a jaw crusher mounting attached to the support frame for mounting the service tool on the jaw crusher. The support frame is movable about first and/or second articulation axes between a transport position and an item supporting position on the jaw crusher.

Systems, methods and apparatus are provided for crushing rock. In some embodiments a toggle feature of a jaw crusher is in tension during operation. In some embodiments a lower portion of the moveable jaw moves simultaneously moves closer to the stationary jaw and forward along said first direction. In some embodiments, a direction along which material moves between the moveable and stationary jaws is closer to horizontal than vertical.
