"STEWART" All Purpose Dump Bucket

The bucket is 6' in diameter x 4' deep (4 yards), 6 ton capacity. It has a concrete spout and 8" x 8' elephant trunk which can be easily removed. The bucket is always horizontal when lifted by the main hook alone or with the auxiliary hook slack. The bucket is tilted towards the crane operator when the auxiliary hook is lifted (or the main hook lowered). The crane operator has complete control over the speed and amount of tilt up to 180 degrees (upside down) maximum, when the auxiliary hook is lowered the bucket is returned to it's original horizontal position. It may be used to handle any material such as; sand, aggregate, concrete, trash, boulders, or slurrys. 

The advantages over conventional concrete buckets are: Safety, no workers required to pour. Very good pouring control. Low loading height. Large capacity. Simplicty.
