Abstract
A dragline bucket includes a base member defining a first end, a second end, and a third end. The dragline bucket also includes a first side wall, a second side wall, and an end wall extending from the base member proximate to the third end of the base member such that the end wall is connected to each of the first side wall and the second side wall. The end wall includes a first portion connected to the base member such that a first angle is defined between the base member and the first portion. The end wall also includes a second portion extending from the first portion. The second portion is substantially perpendicular to the base member. The end wall further includes a third portion extending from the second portion such that a second angle is defined between the second portion and the first portion.

A dragline bucket comprising:
- a base member defining a first end, a second end, and a third end;
- a first side wall extending from the base member proximate to the first end of the base member, the first side wall defining a first edge that is distal to the base member;
- a second side wall extending from the base member proximate to the second end of the base member, wherein the first side wall is laterally spaced apart from the second side wall, the second side wall defining a second edge that is distal to the base member;
- and
- an end wall extending from the base member proximate to the third end of the base member such that the end wall is connected to each of the first side wall and the second side wall, wherein the base member, the first side wall, the second side wall, and the end wall define a material receiving portion of the dragline bucket, the end wall including:
- a first portion connected to the base member, wherein the first portion is disposed such that a first angle is defined between the base member and the first portion, wherein the first angle ranges from 130 degrees to 170 degrees;
- a second portion extending from the first portion, wherein the second portion is substantially perpendicular to the base member;
- and
- a third portion extending from the second portion such that the second portion is disposed between the first portion and the third portion, wherein the third portion is disposed such that a second angle is defined between the second portion and the third portion, wherein the second angle ranges from 170 degrees to 180 degrees.
A machine comprising:
- a boom;
- a rigging assembly adapted to be coupled to the boom;
- and
- a dragline bucket adapted to be coupled to the rigging assembly, the dragline bucket including:
- a base member defining a first end, a second end, and a third end;
- a first side wall extending from the base member proximate to the first end of the base member, the first side wall defining a first edge that is distal to the base member;
- a second side wall extending from the base member proximate to the second end of the base member, wherein the first side wall is laterally spaced apart from the second side wall, the second side wall defining a second edge that is distal to the base member;
- and
- an end wall extending from the base member proximate to the third end of the base member such that the end wall is connected to each of the first side wall and the second side wall, wherein the base member, the first side wall, the second side wall, and the end wall define a material receiving portion of the dragline bucket, the end wall including:
- a first portion connected to the base member, wherein the first portion is disposed such that a first angle is defined between the first portion and the base member, wherein the first angle ranges from 130 degrees to 170 degrees;
- a second portion extending from the first portion, wherein the second portion is substantially perpendicular to the base member;
- and
- a third portion extending from the second portion such that the second portion is disposed between the first portion and the third portion, wherein the third portion is disposed such that a second angle is defined between the second portion and the third portion, wherein the second angle ranges from 170 degrees to 180 degrees.
