ABSTRACT:
The payload capacity of an excavating dipper or bucket for a power shovel or dragline is increased by providing an upper bucket portion having support brackets and the strength to support the rated load of the dipper and a disposable lower portion having opposed sidewalls and a bottomwall of a material thickness less than the upper sidewalls and topwall. The lower sidewalls are secured to the upper sidewalls by interference fitted retaining pins disposed in machined bores formed in the upper sidewalls and the lower sidewalls, respectively. The upper sidewalls may be modified to provide spaced-apart plate members which define a slot for receiving the lower sidewall portions, respectively.
