Abstract:
1. A dragline excavator bucket having two spaced-apart pivot arms pivotally connected to a rear wall of the bucket and connectable to a pair of splayed hoist chains, each of the pivot arms being pivotal about a pivot axis that extends transverse to the bucket and generally parallel to the rear wall and is located below the rim of the rear wall, wherein each pivot arm has an arcuate shape and is dimensioned to extend around the rim of the rear wall of the bucket with clearance between the pivot arm and the rim of the bucket wall when the bucket is in a carry position whereby the pivot arms permit relative movement of the bucket and the pivot arms through an angle greater than 90°, so that the bucket may be moved from a substantially vertical disposition to a carry angle greater than 0° to the horizontal.
