  • Patent number: 5832638
    Abstract: A low draft, high yield, dragline bucket system that has about half the weight of current art. It has a low wide configuration with special highly efficient ground engaging, loading and dumping qualities. The strength, cube accomplishment, simplicity, and unit weight combine to compound efficiencies up to 150% of former buckets. This also compounds the ability of the dragline's scope while reducing its specifications and increasing its capacity. A special precise tilt back and hold and rigging system further increases the bucket capacity and further increases its operating range.
