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.

First claim

The invention claimed is:

1. A method of supplying wear members for excavating equipment to a customer, the method comprising:
providing a one-piece wearable component including an exterior surface, a cavity to receive a base on the excavating equipment, and a through-hole in communication with the cavity, the through-hole including a stop;
inserting a lock into the through-hole such that the lock is (a) secured to the wearable component and in contact with the stop in a predefined release position that permits the wear member to be installed on the base, (b) retained in the release position regardless of whether the base is received in the cavity or the orientation of the wearable component, and (c) adjustable to contact the base to hold the wear member to the base during operation of the excavating equipment; and
shipping the wear member to the customer with the lock secured to the wearable component in the release position.

2. A method in accordance with claim 1 wherein the making the lock includes coupling together a body and a resilient member prior to inserting the lock into the through-hole, and inserting the body and resilient member together as a unit into the through-hole from outside the cavity.

3. A method in accordance with claim 1 wherein making the wearable component includes forming the cavity to include a top wall and a bottom wall spaced apart to receive the base therebetween, and a front wall extending between the top and bottom walls.

4. A method in accordance with claim 3 wherein making the wearable component includes forming the cavity to include spaced apart sidewalls.

5. A method of supplying wear members for excavating equipment to a customer, the method comprising:
providing a one-piece wearable component including an exterior surface, a cavity to receive a base on the excavating equipment, and a through-hole in communication with the cavity;
inserting a body and a resilient member assembled together as a unit into the through-hole from outside the cavity such that the body and resilient member are (a) secured to the wearable component regardless of whether the base is received in the cavity or the orientation of the wearable component, and (b) secured to the wear member such that the body can clear the base to permit installation of the wearable component on the base, and (c) adjustable to contact the base and hold the wear member to the base during operation of the excavating equipment; and
shipping the wear member to the customer with the body and resilient member secured to the wearable component.

6. A method in accordance with claim 5 wherein making the wearable component includes forming the cavity to include a top wall and a bottom wall spaced apart to receive the base therebetween, and a front wall extending between the top and bottom walls.

7. A method in accordance with claim 5 wherein making the wearable component includes forming the cavity to include spaced apart sidewalls.

8. A method of supplying wear members for excavating equipment to a customer, the method comprising:
providing a one-piece wearable component including (a) an exterior surface, (b) a cavity having a top wall and a bottom wall spaced apart to receive the base therebetween, and a front wall extending between the top and bottom walls to receive a base on the excavating equipment, and (c) a through-hole in communication with the cavity;
inserting a thread-free lock into the through-hole to be (a) secured to the wearable component regardless of whether the base is received in the cavity or the orientation of the wearable component, and (b) secured to the wear member such that the lock can clear the base to permit installation of the wearable component on the base, and (c) adjustable to contact the base and hold the wear member to the base during operation of the excavating equipment; and
shipping the wear member to the customer with the body and resilient member secured to the wearable component.

9. A method in accordance with claim 8 wherein making the wearable component includes forming the cavity to include spaced apart sidewalls.

10. A method in accordance with claim 8 wherein the making the lock includes coupling together a body and a resilient member prior to inserting the lock into the through-hole.
