Abstract:
A dragline bucket includes a bottom wall, a pair of sidewalls and a rear wall that collectively define a cavity. The sidewalls each have a large downward taper of at least about 7 degrees in at least its forward area. In an alternative embodiment, the sidewalls each have an upward taper in its rearward area which alleviates the need for a spreader bar. The dragline bucket collects earthen material with minimal disruption of the material.
