  • Excavator bucket top assembly
    Patent number: 8069593
    Abstract: An excavator bucket top assembly can be completed as an assembly before being attached to other components to form an excavator bucket. The top assembly includes a flat bottom plate and a top plate with two bends, each having relatively simple geometry for ease of manufacturing. Two hinge plates penetrate through the top plate and are joined to both the bottom plate and the top plate. The top assembly includes strategically positioned, continuous weld joints to avoid weld starts and stops that create stress risers. The top assembly produces a torque tube which is stiff and resistant to fatigue.
