ABSTRACT:
A bearer plate for use with rock bolts or friction rock stabilisers has a plate with an earth engaging surface and an aperture. A wall circumscribes the aperture and extends generally away from the plane of the plate. The wall includes a plurality of spaced apart rib formations that extend in a generally radial direction from the aperture. The direction of indentation of the ribs into the wall is opposite to the expected direction of deformation of the wall when subjected to a compressive load applied in the axial direction of the aperture.
