Abstract: A locking arrangement for releasably securing a first member to a second member is provided in which a surface of the first member has anchors projecting therefrom with a lip portion of each anchor transversely extending from an extremity of each anchor. A surface of the second member has a cutout portion defining an opening adapted to lockingly engage an anchor. At least a portion of the cutout has a tongue at the opening thereof shaped to be positioned underneath the lip portion of an anchor to effect locking engagement thereof. During use, a surface of each of the first and second members is arranged by positioning the cutout portion on the anchor following which one member is rotated relative to the other member to thereby effect engagement of the tongue underneath the lip portion. A keeper is then inserted in at least a part of the cutout not occupied by an anchor to releasably secure the first member to the second member, wherein movement between the members is inhibited.

Abstract: A locking arrangement and method of locking a plurality of plate members (1) (FIG. 5) to a base surface, the base surface being provided with a plurality of locking anchors (5) provided in spaced apart relationship thereon. The locking arrangement is particularly suitable to eliminate the requirement for welding wear plates to equipment such as earthmoving equipment, washery and crushing equipment.
