20130333254 | EXCAVATOR WEAR ASSEMBLY - A lock assembly to lock two members together, typically an excavator wear member, such as a tooth, on to an adaptor. The lock assembly has a locking pin with a flange portion and a retaining assembly that receives the locking pin. The retaining assembly includes a locking member, in the form of a locking ring, which deforms radially when a tapered portion of the locking pin is inserted into the retaining assembly. In the locked position, the locking ring engages with the flange portion of the locking pin to prevent withdrawal of the locking pin from the retaining assembly. | 12-19-2013 |
20130152431 | RIGGING ASSEMBLY FOR A DRAGLINE EXCAVATOR - A rigging assembly for a dragline excavator where the rigging assembly has a first upper hoist link and a second upper hoist link. The rigging assembly also has an equalization member extending between the first upper hoist link and the second upper hoist link. The equalization member is formed from a flexible material. | 06-20-2013 |
20130008062 | WEAR ASSEMBLY FOR AN EXCAVATOR BUCKET - A wear assembly for an excavator bucket comprises a cast lip, a lower wing shroud and a retaining member. The cast lip includes two upstanding wing plates. Each wing plate has a wing face on a side of the wing plate and a plate retaining formation formed on the wing face. The plate retaining formation has a plate retaining face. The wing shroud is mounted to the wing plate. The wing shroud includes a shroud retaining formation having a shroud retaining face. The retaining member includes a first bearing formation having a first face opposing and engaging the shroud retaining face, and a second bearing formation having a second face opposing and engaging the plate retaining face. The retaining member has a longitudinal axis extending between the first bearing formation and the second bearing formation. The longitudinal axis is located in a plane substantially parallel to the wing face. | 01-10-2013 |
20120304506 | MOUNTING OF WEAR MEMBERS - An excavator tooth assembly comprises a first wear member and a second wear member. The second wear member is releasably mountable on the first wear member. The first wear member has a lock face. The second wear member also has a lock face. The lock face of the first wear member opposes the lock face of the second wear to define a lock passage therebetween when the second wear member is mounted on the first wear member. The excavator tooth assembly includes a lock pin which is adapted to be received in the lock passage to releasably secure the second wear member to the first wear member. | 12-06-2012 |
20120260540 | EXCAVATOR WEAR ASSEMBLY - A wear assembly having an adaptor with a spigot portion is disclosed. The spigot portion has a transverse dimension. The wear assembly also has a wear member releasably mountable on the adaptor. The wear member has a body with a socket cavity and the socket cavity is adapted to receive the spigot portion of the adaptor. The wear member also has a pair of mounting ears extending from the body. Each of the mounting ears has a transverse dimension. The transverse dimension of each mounting ear is in the range 0.25 to 0.4 of the transverse dimension of the spigot portion. | 10-18-2012 |
20120260539 | LOCK ASSEMBLY FOR AN EXCAVATOR WEAR MEMBER - A lock assembly for an excavator wear assembly, the lock assembly a locking pin having at least one dowel extending outwardly therefrom. The lock assembly also includes a retaining member having a seat and a cavity and a biasing member located within the cavity of the retaining member. The biasing member is adapted to exert a biasing force on the dowel to releasably retain the dowel within the seat of the retaining member. | 10-18-2012 |
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 |
