Abstract: A wear protector system for shielding the leading edge of an earthmoving implement such as a loading bucket includes an arrangement of shrouds which cover the leading edge between the laterally spaced digger teeth. Each shroud has a nose portion that wraps around the leading edge and a rearwardly extending tail portion having an abutment surface that engages an undercut abutment surface of an anchor block that is welded to the bucket.

Abstract: A lip shroud system which requires no additional hardware to hold a lip shroud on the front lip of an excavation bucket. The front shroud is held by mating lugs to the adapter and to an adjacent tooth pinned to the adapter. The lip bottom is protected by a wear plate held on the front lip by the front shroud. The front shroud is out of engagement with the lip. Thus, even if the lip shroud should loosen, it does not cause wear on the lip. The front shroud wedges between adjacent parts of the adapter, sideways movement of the adapter is virtually eliminated. This greatly reduces the lip wear in the adapter area. The front lip of the assembly is protected by the front shroud which is locked in place by the teeth associated with the adapter for coupling the tooth to the bucket wherein no additional weight is added to the system because no additional hardware is required for connecting the shroud to the bucket, thereby minimizing costs.

When assembled the load transferring surfaces are in mating contact with the laterally disposed flange of the protector mounting lug. First and second pairs of aligned openings are located in the lip protector and, when assembled, are in general alignment with the openings located in each boss of the pair of bosses. Flex pins are disposed in the openings to secure the lip protector to the protector mounting lug.
