Lightweight hybrid material reciprocating sieve

Abstract

A frame for reciprocating sieve assembly comprises a first side member (300, 308) that is elongate and extends longitudinally; a second side member (302, 310) that is elongate and extends longitudinally; a third side member (304, 312) that is elongate and extends transversely; a fourth side member (306, 314) that is elongate and extends transversely; a first hanger mount (206L, 210L) coupled to and extending between the first side member and the third side member; a second hanger mount (208L, 212L) coupled to and extending between the first side member and the fourth side member; a third hanger mount (206R, 210R) coupled to and extending between the second side member and the third side member; and a fourth hanger mount (208R, 212R) coupled to and extending between the second side member and the fourth side member; wherein the first side member, the second side member, the third side member, and the fourth side member are comprised essentially of an aluminum alloy; and wherein the first hanger mount, the second hanger mount, the third hanger mount, and the fourth hanger mount are comprised essentially of a ferrous alloy.
