A rigging assembly for a dragline bucket has first and second hoist chains coupled to the bucket and first and second pickup links above the hoist chains. The chains extend along first and second axes, respectively, and define a fleet angle between them. In the improvement, the pickup links define a link angle between them which is substantially equal to the fleet angle. The pickup links are coupled with respect to respective hoist sockets by pins, the hoist chains are coupled with respect to the pickup links by other pins and all of the pins have substantially equal cross-sectional areas. Most preferably, the pins are identical to one another for parts "commonality. |
