Abstract: A hydraulic excavator tool adapted to be secured to the distal working end of an excavator boom including a main tool assembly with a tool framework, a spaced apart pair of connection flanges fast with the tool framework, and, a structural tubular casing integral with the tool framework extending across and through the tool framework and through the flanges, plus a rotary hydraulic actuator within the tubular casing extending between the connection flanges and providing a rotational drive motion to a drive axle extending between the connection flanges adapted to provide a controlled rotary drive motion of the axle adjacent the connection flanges, and a working tool framework fast to the axle adjacent each of the connection flanges for relative controlled rotation of the working tool framework about the drive axle between the tool framework and a working position.

Abstract: An assembly for an excavator includes a bucket having coupling flanges spaced apart from each other. The coupling flanges extend upwardly from a top wall of the bucket and laterally between side plates of the bucket. Each coupling flange has an aperture. The assembly also includes a linkage assembly coupled to the bucket and configured to tilt the bucket relative to an arm of the excavator. The linkage assembly includes: a top mount configured to be fixedly releasably coupled to the arm of the excavator; a shaft fixedly coupled to the top mount and received in each of the apertures such that the bucket is pivotally coupled to the shaft; a drive lug coupled to and depending from the shaft between the coupling flanges; and a linear actuator coupled to the bucket and the drive lug to pivot the bucket about the shaft.

Abstract: For use with a front-end loader etc, the coupler-assembly provides a rigid connection between the pivoting arm-end and the bucket. Included is a slider-block, guided in slide-guides and slider-slots in side-plates of the frame of the arm-end. Sliding the block using a hydraulic slider ram, wedges the bucket lugs tightly into the frame. The slider-ram is integrated into and moves with the block. A lock-spring urges a lock-bolt into position to lock the bucket-lug to the arm-end frame. A lock-ram releases the lock-bolt, to permit disengagement.
