Abstract
A ground-engaging wear part for earth working equipment that includes a cap received in an opening to overlie a lock and/or sensor. The cap may engage a lock to facilitate movement of the lock or a lock component without needing to remove the cap, protect an underlying sensor and/or limit the ingress of fines.
Claims32
A lock for securing a ground-engaging wear part to earth working equipment, the lock comprising:
- a body having an inner portion for selectively contacting a base of the earth working equipment to secure a wear member to the base, and an outer portion;
- and
- a cap attached to the outer portion of the body such that movement of the cap results in a corresponding movement of the body.
A lock for securing a ground-engaging wear part to earth working equipment, the lock comprising:
- a body having an inner portion for selectively contacting a base of the earth working equipment to secure a wear member to the base, an outer portion with a recess;
- a sensor contained in the recess in the body;
- a cap received in the recess in the body outward of the sensor to protect the sensor;
- and
- at least one fastener to secure the cap to the body.
A ground-engaging wear part for earth working equipment comprising a wear member and a lock,
- the wear member including a hole for receiving the lock, and
- the lock including (i) a body having an inner portion for selectively contacting a base to secure the wear member to the base, and an outer portion, and (ii) a cap attached to the outer portion of the body such that movement of the cap results in a corresponding movement of the body.
A cap for attachment to a lock for securing a wear member to earth working equipment, the cap comprising:
- a body adapted to be received in a lock opening of a wear member, the body including a tool-receiving formation to be engaged by a tool for moving the cap;
- and
- a shank extending from the body, the shank having a smaller width than the body for mating receipt within a recess in the lock and possessing sufficient strength to move the lock when a tool moves the cap.
