Abstract

A jaw crusher includes a stationary crusher jaw and a movable crusher jaw between which a crushing chamber and a crushing gap are formed. The movable crusher jaw can be driven by a crusher drive to generate a crushing motion. An overload protection mechanism includes a control unit, which, in the event of an overload, causes the crusher jaws to move relative to one another in such a way that the crushing gap is enlarged. An actuator unit is driven by the kinetic energy of a driven component of the jaw crusher, in particular the flywheels or the crusher drive driving the flywheels and the movable crusher jaw. At least one actuator is acted upon by the actuator unit using a transfer medium to effect the gap adjustment.
