Abstract
A member for assembly with other members in an assembled condition to form an excavation bucket, the member forming at least part of one of the walls of the bucket when in its assembled condition, the member comprising a body having a forward edge; a rearward edge; opposite inner and outer surfaces that extend between the edges; a first portion of the member being thicker between its inner and outer surfaces than a second portion of the member, the first portion being disposed forward of the second portion.

A lip for assembly in an excavation bucket in an assembled condition, the lip comprising:
- a base portion having a front edge that forms part of a digging edge of the bucket in use and a rear edge for joining to at least one other member of the bucket when the lip is in its assembled condition;
- and
- wing members extending from opposed sides of the base portion, each wing member having:
- a forward edge;
- a rearward edge;
- opposite inner and outer surfaces that extend between the edges;
- a first portion of the member being thicker between its inner and outer surfaces than a second portion of the member, the first portion being disposed forward of the second portion.
An excavation bucket assembly comprising a first member and a second member, each member having a joint edge that are joined to each other when the members are brought into an assembled condition to at least partly form a wall of the excavation bucket, each of the first and second members having a first portion that is thicker between its inner and outer surfaces than a second portion of the member, the first portion being disposed forward of the second portion.

A member of an excavation bucket for assembly with at least one other bucket member in an assembled condition to form the bucket, the member comprising:
- a body having;
- opposite inner and outer surfaces that respectively define at least portions of inner and outer surfaces of the bucket when the member is in its assembled condition;
- a joint edge that in use joins to a corresponding joint edge of another bucket member
- to form a joint in the excavator bucket;
- and
- a weakened region that is arranged to preferentially deform under load so as to relieve loading in the excavator bucket joint.

A wear member of a wear assembly for assembly with an excavation bucket in an assembled condition, the wear member having an inner face that engages the excavation bucket when the wear member is in its assembled condition and an opposite outer face, the wear member comprising:
- a wrapping portion configured to wrap around an edge of the excavation bucket when in the assembled condition;
- and
- a leg extending away from the wrapping portion;
- wherein
- the inner face of the wear member bulges along a substantial portion of the leg for receipt in a recess of the excavation bucket when the wear member is in its assembled condition.

An excavation bucket assembly comprising:
- a first bucket member having a forward edge and a rear edge;
- a second bucket member having a forward edge and a rear edge, the first and second bucket members also each having a joint edge which join to each other when the bucket members are brought into an assembled condition;
- and
- a wear member for protecting at least part of the forward edge of at least one of the bucket members, the wear member comprising a wrapping portion configured to cover the part of the forward edge of the bucket member(s) when the wear member is brought into an assembled condition with the bucket members and a leg extending away from the wrapping portion, the leg configured to be received in a recess formed in at least one of the bucket members when the wear member is in its assembled condition with the bucket members.

A member of an excavation bucket for assembly with at least one other bucket member in an assembled condition to form the bucket, the member comprising:
- a body having opposite inner and outer surfaces that respectively define at least portions of inner and outer surfaces of the bucket when the member is in its assembled condition;
- and
- a shear support formation integrally formed with the body for protecting a wear member that is assembled with the member of the excavation bucket against shear forces in use.
64-65. (canceled)
An excavation bucket assembly comprising:
- a bucket member for assembly with at least one other bucket member in an assembled condition to form the bucket, the member comprising a body having a forward edge and a rearward edge and opposite inner and outer surfaces that respectively define at least portions of inner and outer surfaces of the bucket when the member is in its assembled condition;
- and
- a wear member for assembly with the bucket member to protect at least part of the forward edge of the bucket member;
- wherein
- the bucket member also comprising a shear support formation integrally formed with the bucket member's body for protecting the wear member in its assembled condition with the bucket member against shear forces in use.
