| 20110314709 | Lock For An Excavator Wear Assembly - A lock for an excavator wear assembly. The lock has a first member a key way located on an internal face of the first member. The lock also has a second member having a key located on an internal face of the second member such that the key is receivable within the keyway of the first member. Furthermore, the lock has a fastening member receivable within the first member and the second member to thereby releasably secure the first member to the second member. | 12-29-2011 |
| 20110167682 | HEAVY DUTY EXCAVATOR BUCKET - A heavy duty excavator bucket is constructed with an exoskeletal structure comprising coupled cast components including a lip member, opposed wing members, junction members locatable between floor and side walls and side and rear walls and a cap rail structure extending between opposed wing members about the upper periphery of the bucket to form an integral structure. Steel plate floor, side wall and rear wall members extend between adjacent exoskeletal regions. The bucket may include a cast arch member extending between opposed wing members and a cast reinforcing member extending between opposed junction members adjacent said rear wall. | 07-14-2011 |
| 20110058894 | A LOCK ASSEMBLY FOR AN EXCAVATOR WEAR MEMBER - A lock assembly for releasably securing an excavator tooth on a nose of an excavator. The lock assembly has a rigid lock member having a base portion and a retaining portion extending from the base portion. The base portion is adapted to be located in a retaining cavity of the nose and the retaining portion adapted to at least partially extend into a retaining aperture of the wear member. The lock assembly also has a resiliently deformable lock member, in use, adapted to be located within the retaining cavity of the nose to abut an upper face of the rigid lock member to thereby captively retain the base portion of the rigid lock member in the retaining cavity and the retaining portion at least partially within the retaining aperture such that side walls of the retaining portion of the rigid lock member bear against complimentary side walls of the retaining aperture of the wear member and opposed bearing faces of the base portion of the rigid lock member oppose and engage respective side walls of the retaining cavity of the nose of the excavator to thereby releasably secure the wear member on the nose of the excavator. | 03-10-2011 |
| 20100162595 | MOUNTING OF WEAR MEMBERS - A retaining pin assembly for an excavator tooth assembly. The retaining pin assembly has opposable locating members each having a shank portion able to be slidably insertable via a respective retaining pin aperture on opposite sides of a wear member into a transversely extending mounting aperture of a mounting nose of an excavator. Each locating member also has an enlarged inwardly convergent tapered wedge portion adjacent a normally outer end. The retaining pin assembly also has a tensionable retaining member extending between the locating members from one side of the retaining pin assembly. When tension is applied to the retaining member relative contraction of the locating members occurs to urge the wear member into engagement with the mounting nose by wedging engagement between each of the wedge portions and a rear wall of respective retaining pin apertures. | 07-01-2010 |
| 20100005689 | HEAVY DUTY EXCAVATOR BUCKET - A heavy duty excavator bucket is constructed with an exoskeletal structure comprising coupled cast components including a lip member, opposed wing members, junction members locatable between floor and side walls and side and rear walls and a cap rail structure extending between opposed wing members about the upper periphery of the bucket to form an integral structure. Steel plate floor, side wall and rear wall members extend between adjacent exoskeletal regions. The bucket may include a cast arch member extending between opposed wing members and a cast reinforcing member extending between opposed junction members adjacent said rear wall. | 01-14-2010 |
