Abstract
A crusher device such as a cone or gyratory crusher is disclosed. The crusher device includes a shaft defining a first direction parallel to its length. The shaft includes an upper shaft end, a crusher head, and an overload safety device that couples the crusher head to the upper shaft end. The overload safety device includes a biasing device configured to bias the crusher head away from the upper shaft end in the first direction. The overload safety device is configured to permit displacement of the crusher head along the first direction relative to the shaft in response to a force acting on the crusher head in the first direction.
