Abstract

598988 A mounting bar 1 for a wear part for a rotor of a rock crusher, where the rotor includes a top plate, with an upper surface and a lower surface, and includes an aperture for the mounting bar 1, the aperture passing between the upper surface and the lower surface., and a base plate. The mounting bar 1 includes a shaft 2 configured to receive a wear part, a head 3, and a foot 4 configured to engage with the base plate of the rotor. The mounting bar 1 is characterised in that the head 3 is configured with a lateral protrusion 8 extending from a side of the head 3 to engage with a tapered or stepped portion of the aperture passing between the upper surface of the top plate to its lower surface. The protrusion 8 is dimensioned such that it is larger than the cross-sectional area of the shaft 2 of the mounting bar 1.
