Abstract
A gyratory crusher frame part and a gyratory crusher include a topshell and spider assembly configured to minimize stress concentrations. An annular flange is formed at the junction between a lower region of each spider arm and an upper region of the topshell. Optimization of loading force transfer and a reduction in stress concentration is achieved by positioning the spider arms radially inward relative to an outer circumferential perimeter of the flange.
