Abstract
A gyratory crusher frame part includes a topshell mountable on a bottom shell, the topshell having an annular wall extending around a longitudinal axis. A spider having a plurality of arms extending radially outward from a cap is positioned at the longitudinal axis. Each arm has a first portion extending in a radially outward direction from the cap and a second portion extending in an axial direction from an outer region of the first portion. An annular flange is positioned between the second portion of each arm and the annular wall. The annular wall is defined between an outward and inward facing surface of the annular wall. A section of the wall neighboring the flange includes a concave section at the outward facing surface. A first half of the concave section closest to the flange is a substantially uniform curve extending continuously in the circumferential direction around the longitudinal axis.
