Abstract
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.
Claims28
A wear member for attachment to excavating equipment comprising a front end to contact materials being excavated and protect the excavating equipment, a rear end, a socket that opens in the rear end to receive a base fixed to the excavating equipment, a through-hole in communication with the socket, and a lock integrally connected in the through-hole and movable without a hammer between a hold position where the lock can secure the wear member to the base and a release position where the wear member can be released from the base, the lock and the through-hole being cooperatively structured to retain the lock in the through-hole in each of said hold and release positions irrespective of the receipt of the base in the socket or the orientation of the wear member.
A wear member for attachment to excavating equipment comprising a front end defining a narrow front edge for penetrating into the ground, a rear end, a socket defined by top, bottom and side walls that opens in the rear end to receive a nose fixed to the excavating equipment to define an excavating tooth, a through-hole in communication with the socket, and a lock received in the through-hole for pivotal movement between a hold position where the lock secures the wear member to the nose and a release position where the wear member can be released from the nose, wherein the pivotal axis extends in a direction generally parallel to the receipt of the base into the socket.
A wear member for attachment to excavating equipment comprising a front end to contact materials being excavated and protect the excavating equipment, a rear end to mount to a base fixed to the excavating equipment, and a lock movable between a hold position where the lock secures the wear member to the base and a release position where the wear member can be released from the base, wherein the lock remains secured to the wear member in the release position irrespective of whether the wear member is mounted to the base or the orientation of the wear member.
A wear member for excavating equipment comprising:
- a wearable body having a wear surface to contact materials being excavated and protect the excavating equipment, and a cavity to receive a base fixed to the excavating equipment;
- and
- a lock integrally secured to the wearable body for movement between a hold position wherein the lock engages the base to hold the wearable body to the base and a release position wherein the lock permits installation and removal of the wearable body on and from the base, the lock being secured to the wearable body in both the hold and release positions irrespective of whether the base is in the cavity or the orientation of the wear member.
A wear assembly for attachment to excavating equipment comprising:
- a base fixed to the excavating equipment;
- a wear member including a front end to contact materials being excavated and protect the excavating equipment, and a rear end to mount to the base fixed to the excavating equipment;
- and
- a lock integrally connected to the wear member and movable without a hammer between a hold position where the lock contacts the base and the wear member to secure the wear member to the base and a release position where the wear member can be released from the base, wherein the lock remains secured to the wear member in the release position.
A wear assembly for excavating equipment comprising a base fixed to the excavating equipment and a wear member having (i) a wearable body having a wear surface to contact materials being excavated and protect the excavating equipment, and a cavity to receive a base fixed to the excavating equipment, and (ii) a lock integrally secured to the wearable body for movement between a hold position wherein the lock engages the base to hold the wearable body to the base and a release position wherein the lock permits installation and removal of the wearable body on and from the base, the lock being secured to the wearable body in both the hold and release positions irrespective of whether the base is in the cavity or the orientation of the wearable body.
A wear assembly for excavating equipment comprising:
- a base fixed to the excavating equipment, the base having a nose free of moving components;
- a wear member including a front end to contact materials being excavated and protect the excavating equipment, and a rear end having a socket for receiving the nose to support the wear member on the base;
- and
- a lock movably secured to the wear member for movement between a hold position where the lock engages the base and the wear member to secure the wear member to the base, and a release position where the wear member can be released from the base, the lock remaining secured to the wear member irrespective of receipt of the nose into the cavity or the orientation of the wear member.
