1. A dragline bucket, comprising:
- a main body moveable between a digging orientation and a dumping orientation;
a pivotable spreader beam coupled to the main body at a pivot point, wherein the main body is configured to move from the digging orientation to the dumping orientation by rotating downward about the pivot point relative to the pivotable spreader beam in order to empty the contents of the bucket; and
an energy capture mechanism comprising;
an actuator coupled to the main body and the pivotable spreader beam; and
an energy storage device coupled to the actuator, wherein the main body is configured to compress the actuator when the main body moves from the digging orientation to the dumping orientation, causing the actuator to transfer energy to the energy storage device.
