Abstract
A bucket for a dragline has a pivoted mounting by having two spaced pivotal arms, typically of arcuate or cranked form, pivotally connected to the outside of a rear wall of the bucket about pivot axes extending transverse to the bucket and below the upper rim of the bucket whereby pivotal connections at the upper end of each pivot arm may be disposed over the rim and within the bucket zone. Thus the pivot arms may be moved in use through greater than 90° from a position in which the bucket is vertically suspended. The pivot arms act to spread splayed hoist chains without a spreader bar.
