Wear assembly for excavating equipment
First Claim
1. A wear member for excavating equipment comprisinga working section and a mounting section generally aligned along a longitudinal axis, the mounting section including a socket for receiving a base fixed to the excavating equipment to mount the wear member on the excavating equipment, and the working section being that part of the wear member forward of the socket,a leading side adapted to be a forward surface during advance of the wear member through the ground during a digging operation, anda trailing side adapted to be a rearward surface during advance of the wear member through the ground,the leading and trailing sides extending axially across the working and mounting sections, and the leading side having a greater width than the trailing side in transverse cross sections perpendicular to the longitudinal axis along at least part of the working section and the mounting section.

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.
