  • Publication number: 20060283056
    Abstract: A backhoe or excavator is adapted for use in lifting and transporting objects such as logs, beams, and the like, by a gripping attachment that functions in conjunction with the backhoe bucket. The gripping attachment consists of one or more, preferably two, plates that have a scalloped contact edge in the form of a series of convex curved protrusions while the protrusions themselves are arranged in a concave curve. The attachment is mounted or capable of being mounted to the surface of the boom at a location a short distance above the pivot axis of the bucket on the side of the boom that is also faced by the bucket opening. When the bucket is thus rotated back toward the attachment, an object to be lifted or transported can be securely held between the bucket and the scalloped edge with no damage to the surface of the object.

  • Publication number: 20060045714
    Abstract: A laterally tiltable bucket for earth-moving equipment and the like is constructed with a flat plate of unitary construction attached to, and extending the full width of, the bucket, as a support for one or a pair of hydraulic cylinders whose axes are arranged parallel to the flat plate. When two cylinders are used, the pistons of the cylinders meet at a common linkage in the center. Various additional features, including construction of load-bearing portions of the bucket and the bracket to which the bucket is mounted, are joined at right-angles to simplify construction and increase the strength of the assembly.
