Abstract: A jaw crusher includes a crushing chamber between a fixed jaw and a swing jaw. The jaw crusher also includes an eccentric drive which supports the first end of the swing jaw. The second end of the swing jaw is supported on a rocker plate. The counter-bearing of the rocker plate is arranged as a cross-member and is supported on a hydraulic overload protection mechanism. The cross-member is retained in lateral rocker arms held coaxially to the eccentric shaft of the eccentric drive. The lever axis of the rocker plate projects in a direction of the eccentric shaft and with this projection encloses an acute angle with a radial line of the eccentric shaft. The radial line passes through the counter-bearing of the rocker plate.
