摘要： A connection for firmly securing an adapter for detachably carrying a replaceable digging tooth at its front end to a lip of an excavating container of excavating equipment. The adapter has an upper leg and a lower leg located proximate respective upper and lower surfaces of the lip. The connection has substantially aligned openings in the legs and the lip, and engagement sections of the adapter legs traverse the opening in the lip proximate and forward of an aft end thereof. A pressure applying unit, such as a hydraulic actuator, is arranged inside the opening and generates a generally horizontally acting force which draws the adapter and the lip towards each other. A stress member, which can be a C-clamp, is operatively coupled to the hydraulic actuator and resiliently deforms relative to its relaxed shape when it is subjected to the horizontally acting force. A spacer, such as a wedge, is inserted between the hydraulic actuator and the openings while the horizontally acting force resiliently deforms the stress member. The wedge is shaped so that upon a reduction or cessation of the horizontally acting force the stress member, e.g. the C-clamp, remains in the resiliently deformed state in which it draws the adapter and the lip towards each other and keeps them immovably secured to each other until the wedge can be withdrawn following a repressurization of the hydraulic actuator.

摘要： An excavating bucket assembly for excavation apparatus that does not use pins to connect teeth to adaptors on the excavation bucket. Each adaptor includes a receiving portion defined therein that is at least partially defined by an abutment wall. Each tooth includes an interference portion. The connection system includes a biasing portion adjacent the abutment wall and a locking portion adjacent the biasing portion. The locking portion includes a locking section and an interference section that engages the interference portion of its respective tooth. The locking section and the interference section are capable of movement relative to one another to thereby couple the tooth to the adaptor. The locking section included at least one biasing plunger that engaged a corresponding biasing pin within the biasing portion when the connection system is in use.

摘要： The present fastener securely couples a first body to a second body, where the fastener includes an elongate arcuate body curved along a longitudinal axis and having a cross-sectional area taken planar normal to the longitudinal axis, the elongate arcuate body includes a first portion separated along the longitudinal axis from a second portion with the cross-sectional area of the elongate body increasing from the first portion to the second portion. The fastener further includes a retaining portion configured to selectively secure the elongate arcuate body in the inserted configuration. In use, the present fastener is configured to be inserted into a passage delineated between a first body and a second body which are overlapping at least in part, to selectively lock the first body and the second body in the coupled configuration.

摘要： A method and apparatus for installing and removing shrouds from the lips of an earth moving bucket. The lips have forwardly converging upper and lower surfaces which are engaged by correspondingly rearwardly diverging legs of the shrouds that overly and are in contact with the lip surfaces. A hole is provided in the lip and an oblong hole in one of the legs that is aligned with the hole and has axially extending, spaced-apart flat walls which define engagement ledges that face and overlap the bore. A connector for securing the shroud to the lip is placed in the bore and the hole and has shaped exterior surfaces for positioning between the walls so that the connector is axially movable along the walls and past the engagement ledges while relative rotations between the connector and the hole in the leg are prevented.
