ABSTRACT:
A hydraulically operated clamshell bucket including left and right bucket halves pivotally supported by a bucket carrier. The bucket halves are opened and closed by the operation of a hydraulic cylinder in cooperation with a compensation link. The clamshell bucket provides an improved structural arrangement for transmitting the force from the hydraulic cylinder to the cutting edges of the bucket halves in that for a given size and rated bucket, the weight of the bucket may be reduced along with the complexity and manufacturing cost of the bucket.
