Abstract
The apparatus is a gyratory crusher in which all the wear parts can be removed and replaced from the top of the crusher, thus eliminating the need to remove large, heavy parts from below the crusher. This is accomplished by constructing the crusher so that the eccentric and the piston assembly can be lifted up and out sequentially. The piston assembly then includes all the wear parts within the lowest assembly, the hydraulic support, so that those parts can be replaced without access to the underside of the crusher. If necessary, the hydraulic support within which the piston assembly is held can also be removed from above the crusher.
