  • Patent number: 9187927
    Abstract: A post pulling attachment system which easily attaches and detaches from a bucket to aid in safely and efficiently removing a post from the ground. The post pulling attachment system generally includes an outer securing plate and an inner securing plate which are positioned on either side of a bucket. Each of the securing plates includes a plurality of corresponding apertures through which a pair of removal members are extended both to secure the present invention to the bucket and to aid in removing a post. When installed, the removal members will extend outwardly from the bucket in spaced-apart relationship. By positioning a post between the removal members, rotating the bucket to jam the post therein and then lifting the bucket, a post may safely and efficiently be removed from the ground without use of a chain.

    Abstract: Apparatus and method for material distribution, including a draw-bar to which is fixedly connected a bucket body. Wheels are attached to the drawbar on opposite sides of the bucket body between an open side and a gate thereof. A lower edge of the open side of the bucket body, which can receive material, is in the form of a cutting blade or teeth. The gate, which is disposed opposite from the open side, can be opened and closed. At least part of a top side of the bucket body forms a platform for an operator. At least one engine is provided and is drivingly connected to the wheels. A handlebar is connected to the bucket body, forward of the platform, for pivoting the bucket body about the wheels so that the cutting blade or teeth can be brought into or out of contact with a surface.

  • Publication number: 20080060231
    Abstract: A hydraulically-operated ripper tool mounted as an attachment on a hydraulic aim of a carrier or excavator is used for demolition of large metal walled structures such as storage tanks in a very short time. The ripper tool has a sharp point for punching entry holes into the tank walls, so that no torch cutting of entry holes needs to be used, particularly where there might be volatile residues left in the tank. The ripper tool has a concave, sharp inner edge and is operated by the hydraulic aim in reciprocation so as to provide a shearing force to cut quickly through metal walls in “can-opener” fashion. The ripper tool facilitates making long vertical cuts into the tank wall from top to bottom, so that a series of vertical cuts can be made to weaken a side of the tank and allow the top of the tank structure to be brought down.

The shanks and ripper teeth are laterally spaced apart along the axis of rotation relative to the arm, and the ripper teeth are angularly spaced apart in a direction of substrate ripping motion. In some implementations, plates are mounted to span a region between two or more shanks, rearward of the teeth in a direction of ripping motion, and define, with the shanks, a bucket volume for receiving material ripped from the substrate. Methods for ripping excavation of a substrate employing the above excavation tools mounted on a dipper stick or a boom arm are also described.

    Abstract: An excavation attachment for a powered loader, e. g., skid steer loader, front end loader, etc., provides considerably greater leverage for removal of stumps, large imbedded concrete blocks and stones, etc., from the underlying surface. The attachment includes a transverse cylinder or drum with one or more tines extending generally radially therefrom. The attachment is secured to a conventional front end loader, skid steer loader, etc., and the tines inserted beneath the object to be moved. The drum is lowered, and the attachment is rotated using conventional load bucket tilt hydraulics. The drum serves as a fulcrum immediately adjacent the prying tines, thereby providing a considerable increase in available force and precluding lifting of the opposite end of the machine if the load is too great.

  • Patent number: 5819445
    Abstract: An accessory attachment/conversion assembly is disclosed for use on a small front-end loader type of construction implement. One form of accessory would be a backhoe bucket. The attachment assembly includes a frame for detachable mounting to the implement and includes a rotatable drum pivotally secured to the frame and rotatable in its mounting by means of chains, or other suitable forms of transmission means, which are secured at one of their ends to the drum and at their other ends to a hydraulic cylinder mounted on the frame. An elongated arm or boom is secured at one end to the drum and extends outwardly thereof. The outer terminal end of the boom can carry a bucket or other suitable accessory. The arrangement being such that the boom and bucket can be swung approximately full left to full right, almost 180.degree..

  • Patent number: 5794370
    Abstract: A new Tiered Trenching Backhoe Apparatus for creating a dual tiered trench which allows one service utility to be elevated above another service utility thereby preventing contact of the two service utilities resulting in increased safety. The inventive device includes a syncline plate with an interior angle of approximately 140 degrees, a first and second triangular coupler welded at one end to the syncline plate removably coupling to a pair of existing tooth shanks of a backhoe bucket, a first and second fluke welded to the syncline plate opposite of the triangular couplers, a first and second trihedral support members welded to the interior portion of syncline plate providing support, and a pair of replaceable teeth removably secured to the first and second flukes.

  • Patent number: 5490340
    Abstract: A root grubber tool for brush which is attached to the boom of an excavator, such as, a track excavator or backhoe. The tool includes a framework which has a pair of side members which support, at the lower end thereof, a cutting blade with its leading edge swept inward and downward to accommodate centering the cutting blade on the roots and providing a deeper cut at the center than at the edges. The framework includes mounting arms to secure the tool onto the boom for working the tool. The framework may include a cross support for assisting in gathering smaller brush. Also, the lower edges of the side members are bevelled to aid in the cutting operation. The tool may be maneuvered to depths of 18 to 24 inches to grub out the roots of the brush and secure it between the boom and the tool for displacement from the right-of-way.

  • Patent number: 5456028
    Abstract: In an excavating apparatus including a bucket removably coupled to a distal end of a hydraulically powered boom, a field-detachable and field-attachable ripper comprises a shank portion having a lower tip, a mounting portion disposed along an upper area of the shank portion and a detachable and re-attachable coupling element disposed along the mounting portion. The detachable and re-attachable coupling element secures the ripper to the bucket. There is optionally further included a detachable ripper tip coupled to the lower tip. The detachable ripper tip comprises a metal piece having a point disposed at a first end thereof and having a hollow disposed at a second end thereof. The hollow is adapted to accommodate the lower tip therein. The detachable ripper tip further includes an opening disposed on one side thereof and extending into the hollow. The opening is adapted to accommodate a fastener extending from the side and into the lower tip.

  • Patent number: 5394629
    Abstract: An upper end portion of an excavation ripper shank is captively and removably retained in a ripper box using a specially designed flex pin connector longitudinally driven into generally aligned openings in the ripper box and shank. The connector includes first and second rigid pin members held in a spaced apart, parallel, laterally facing relationship by a plurality of elastomeric members bonded to facing side surfaces of the pin members. When the connector is driven into the aligned box and shank openings the elastomeric members are compressed, causing the first and second pin members to drive the shank and box into forcible abutment with one another to substantially eliminate relative side-to-side play therebetween. Additionally, as the connector passes through the first and second openings its first and second pin members are caused to pivot relative to one another about an axis parallel to the compression direction of the elastomeric members.
