A jaw crusher (100), a crushing plant (299), and a method for using a crusher, wherein a toggle plate (7) is coupled between a pitman and a rear end of the jaw crusher with bearings at the ends of the toggle plate. There is a bearing holder (12) for the bearing at least at one end of the toggle plate. The bearing (13) is transferred continuously in the bearing holder (12) to a desired location between an upper and a lower limit, inclusive of the upper and lower limit, with a transfer member (22) comprised by the bearing holder, and thus the operating angle of the toggle plate in relation to a frame of the crusher and the stroke of the crusher are changed. |
