摘要： A wear member (12) for attachment to excavating equipment comprises a front end (44), a rear end (46) and a socket (16) that opens in the rear end (46) for receiving a base (14) fixed to the excavating equipment. The socket (16) includes a main portion (56) having an upper side (58) and a lower side (56) each having a central facet (64, 68) and two opposite side facets (66, 70) each transversely inclined to the corresponding central facet, the upper central facet (64) having a width that expands in a rearward direction. The lower central facet (68) has a width that narrows in a rearward direction. The side facets (70) of the lower side (60) axially extend substantially parallel to the longitudinal axis to bear against the base and resist certain loads, and are transversely angled to resist vertical and side loads.

摘要： A wear member (12) for attachment to excavating equipment comprising a front end (44) defining a narrow front edge for penetrating into the ground, a rear end (46), a socket (16) defined by top, bottom and side walls that opens in the rear end (46) to receive a nose (14) fixed to the excavating equipment to define an excavating tooth. The wear member (12) has a through-hole (81) in communication with the socket (16). A lock (17) is received in the through-hole (81) for pivotal movement between a hold position where the lock (17) secures the wear member (16) to the nose (14) and a release position where the wear member (15) can be installed on the nose (14), wherein the pivotal axis extends generally in an axial direction. Typically the lock (17) is maintained in the opening (81) irrespective of the insertion of the nose into the cavity, and can include a latch formation (115) to secure the lock (17) in the hold and release positions.

摘要： A wear member (12) for attachment to excavating equipment comprising a front end (44), a rear end (46), a top side, a bottom side, and a socket (16) that opens in the rear end to receive a base (14) fixed to the excavating equipment. The socket (16) has a front end portion (48), a rear end portion (56) and a longitudinal axis, the front end portion (48) including a first surface (52) extending substantially across the width of the front end portion (48) along one of the top or bottom sides to bear against the base and resist vertical loads. A pair of second surfaces (54) face in a direction generally opposite to the first surface (52), the second surfaces (54) being transversely inclined to reduce the spacing of outer corners in the socket (16) along the other of the top and bottom sides and to bear against the base and resist vertical and side loads, wherein the first and second surfaces (52, 54) each axially extend substantially parallel to the longitudinal axis.

摘要： A wear member (12) for attachment to excavating equipment comprises a front end (44), a rear end (46), and a socket (16) that opens in the rear end to receive a base (14) fixed to the excavating equipment. The socket (16) is defined by top, bottom and side walls, and characterized by the rear end having an offset portion defining a shoulder (72) along each side wall to bear against the base (14) and resist vertical loads. The shoulders (72) face generally downward with the top wall (58) extending between each of the shoulders (72) and farther rearward than the bottom wall (60). Furthermore the shoulders (72) axially extend substantially parallel to the longitudinal axis of the socket (16) to bear against the base and resist vertical loads. The socket (16) can include stabilizing surfaces (70) that axially extend substantially parallel to the longitudinal axis and face in a direction generally opposite to the shoulders (72) to bear against the base, and be transversely inclined to bear against the base and resist both vertical and side loading.
