ABSTRACT:
A spider for use with a gyratory crusher. The spider includes spider arms each formed from two spaced flanges joined by a connecting web to define an open channel having an open top end. The configuration of the spider arms increases manufacturability and provides the required strength and rigidity for the spider. The channel formed in each spider arm is covered by a spider arm shield to reduce abrasive wear to the spider arm.
