Abstract
Wear caps protect the wearable surfaces of an adapter for an earth working equipment. These wear caps are subjected to erosion and wear by contact with abrasive material, such as experienced in an excavating operation. The wear caps can be attached to upper and lower legs of the adapter and protect them from wear. Each wear cap is secured to a retention feature on an independent mounting structure. The independent mounting structures are aligned and staggered such that installation of a wear cap onto the rearward independent mounting structure is conducted first. The independent mounting structures on an upper leg may be situated one above the other.
Claims35
A wear assembly for earth working equipment comprising:
- an adapter including a forwardly projecting nose and a leg extending rearward of the nose that is adapted to overlie and be secured to a digging edge of a bucket, the leg having a first surface to face the digging edge and an opposite second surface, wherein the inner second surface has at least two independent retention structures;
- a wear member having a cavity that receives the nose;
- a lock to secure the wear member to the adapter;
- and
- a plurality of wear caps, wherein each said wear cap is mounted on a different one of the at least two independent retention structures.
An adapter for earth working equipment, the adapter comprising
- a forwardly projecting nose for mounting a wear member,
- a leg extending rearward of the nose that is adapted to overlie and be secured to a digging edge of a bucket, the leg having a first surface to face the digging edge and an opposite second surface, and
- at least two independent retention structures for mounting wear caps, wherein each of the independent retention structures is for mounting a different wear cap.
A wear assembly for earth working equipment comprising:
- an adapter including a forwardly projecting nose and an inner surface rearward of the nose, wherein the inner surface has at least two independent retention structures;
- a wear member having a cavity that receives the nose;
- a lock to secure the wear member to the adapter;
- and
- a front wear cap and a rear wear cap mounted on the at least two independent retention structures, and wherein the front wear cap is closer to the digging edge than the rear wear cap.
