Abstract
The present scooper of slipper bucket is attachable to an upper jaw of a grapple connected to the boom structure of a hydraulic excavator. The scooper bucket includes a bucket like rigid enclosure forming a tine receiving opening for receiving a tined jaw of the grapple. The tines of the grapple slide into or are inserted through the opening. Distal tip ends of the tines slide into the holding sockets formed inside the bucket enclosure. A pair of removable hooks affixed to the proximal inner ends of the tines are secured to a shaft mounted to the bucket like enclosure over the tine receiving opening. The scooper bucket is readily connected to the upper jaw and operates to scoop up and remove gravel, dirt or sand.
