| 发明名称 | Jaw crusher | ||
| 摘要 | A jaw crusher having a fixed jaw and a swing jaw disposed between opposing side walls of the jaw crusher. The swing jaw is movable relative to the fixed jaw for generating impelling forces to crush material present between the two jaws. The jaw crusher includes a cross beam which extends between the opposing side walls and a toggle plate is provided between a rear face of the swing jaw and the cross beam. Pressure cylinders are provided for applying a load to the cross beam, to provide a reaction to forces generated during movement of the swing jaw. The jaw crusher comprises a locking arrangement for selectively preventing substantial movement of the cross beam against the action of the pressure cylinders. | ||
