A gyratory crusher bottomshell and inspection hatch assembly is attachable exclusively to the bottomshell via a wear plate positioned at an internal region of the bottomshell. A wall thickness of the bottomshell at a border region immediately surrounding the hatch opening is generally equal to or less than a wall thickness over a remainder region of the wall at the same axial height position of the hatch opening.

A gyratory crusher topshell having an annular shell wall that is strengthened to minimize stress concentrations and increase the topshell operational lifetime. The topshell includes spider arms that are structurally reinforced at their radially inner regions and also has an annular wall that is reinforced at regions immediately below the spider arms to further increase strength and facilitate casting.
