Abstract

A linkage arrangement for guiding and manipulating a work implement, such as a bucket, includes a V-shaped guide link and a curved implement link. A plurality of pin joints connect the implement link to the bucket, the guide link, and to a fluid cylinder. The fluid cylinder, the guide link, and the implement link cooperate to rotate the bucket between open and closed positions, for digging and carrying materials. The linkage arrangement provides high forces for digging and bucket rotation and desirable lower rotational velocity for clamping object in the fully closed position.
