Abstract: A dredge cutterhead has a plurality of helical arms (32) interconnecting a hub (28) and a ring (30). Each of the arms (32) has a front leading edge (40) for attachment of cutting teeth (34). In one aspect, each of the arms (32) has a trough (44) portion, and the arm (32) is shaped such that dredged material is directed toward the ring (30) along the center of the trough portion (44). In another aspect, the ring (30) of the cutterhead defines an annular channel (66) for receiving loosened material.

Abstract: A wear assembly for excavating equipment includes a base fixed to the excavating equipment, a wear member fit over the base, and a lock to releasably hold the wear member to the base. The wear member includes side relief to reduce drag on the system. The wear member and the base each includes a hemispherical front end and a generally trapezoidal rear portion. The base includes a nose and a stop projecting from the nose to cooperate with the lock without an opening being needed to receive the lock into the nose. The lock is an elongate lock positioned generally in an axial direction and which holds the wear member to the base under compressive loads.

Abstract: A wear member for excavating equipment and which is particularly suited for a dredge cutterhead that includes a curved abutting surface that abuts a complementary curved bearing surface on the base. The curved bearing surfaces are able to maintain substantially full contact with each other under transverse loading. The base and adapter further having a plurality of complementary stops for resisting relative movement between them.
