A multi-piece hammer for use in a reducing machine. The multi-piece hammer includes a base to be mounted to the reducing machine, a replaceable tip to be mounted to the base and to impact the material to be reduced, and a retainer to secure the replaceable tip to the base. The replaceable tip has a cavity with a single rail or groove that corresponds to a single groove or rail on the base.

Hammer for material reducing machines

A wear assembly for excavating equipment which includes a wear member and a base each with upper and lower stabilizing surfaces that are offset and at overlapping depths to reduce the overall depth of the assembly while maintaining high strength and a stable coupling. The nose and socket each includes a generally triangular-shaped front stabilizing end to provide a highly stable front connection between the nose and wear member for both vertical and side loading. The lock is movable between hold and release positions to accommodate replacing of the wear member when needed, and secured to the wear member for shipping and storage purposes.

A wear assembly for excavating equipment that includes a base, a wear part and an improved locking arrangement that provides improved stability, strength, durability, safety and ease of use. The locking arrangement includes a hammerless lock that is pivotally moved between hold and release positions, wherein the fulcrum is set forward of the bearing surface engaging the wear part. The lock can be manipulated by a threaded member or pry tool. The lock further includes bearing surfaces that enhance stability and reduce wear.
