A connector secures the slide hammer to the tamper sleeve, while allowing vertical, slideable motion between the slide hammer and tamper sleeve. The connector also limits the vertical movement of the slide hammer in relation to the tamper sleeve. Rotation between the slide hammer and tamper sleeve is restricted by a tamper bushing/connector configuration within the tamper sleeve. The tamper is adapted for use with different tamper heads, interchangeably connected to the tool. An adjustable handle secured around the tamper sleeve allows the position of the handle to be varied along the tamper sleeve. The tamper tip can be replaced with a new, unworn tip, when necessary.

The tool head assembly has a rubber or similarly resilient material pad bonded to the underside of a backing plate. Connection elements, such as bolts, are permanently secured between the pad and the backing plate. The bolts extend through and are upstanding from the backing plate. The bolts are configured to then extend through openings in the tamper mounting plate, where nuts are used to secure the tool head assembly to the mounting plate. The tool head assembly is thus removeable from the mounting plate and its handle or supporting element and allows for the simple and ready replacement of a used and worn tool head assembly with a new tool head assembly.

    Abstract: Vibratory percussion rammers and methods of making vibratory percussion rammers are provided. In one example, a vibratory percussion rammer includes a gear box, a percussion delivery unit extending downwardly from the gear box, and one or more slide bearings disposed in the percussion delivery unit between adjacent surfaces of reciprocating metal components. The slide bearings include a sheet of non-metal material that is curved into the shape of a tube having a C-shape in cross section. Slide bearings according to this design can be disposed in the percussion delivery unit to eliminate some or all of the metal-on-metal contact between reciprocating components, including between the ram and shaft assembly, spring box and the guide cylinder, the spring separator and the spring box, and the shaft of a ram and shaft assembly and an upper end of the spring box.

  • Patent number: 7491014
    Abstract: The invention relates to a soil compacting system which comprises a travelling and steerable soil compacting device and a control device. The control device is provided with an area definition device which allows a user to establish an area to be compacted and the area boundaries. A position detecting device detects the actual position of the soil compacting device. A traveler changes the direction of travel of the soil compacting device by presetting a standard value for a travelling movement of the soil compacting device in such manner that the soil compacting device does not travel past the respective area boundary but continues its travel within the area. A path planning device may be provided for fixing a presetting for a travel way which makes sure that the soil compacting device, when keeping to the preset travel way, travels at least once completely across the area to be compacted.

  • Patent number: 7484912
    Abstract: A method and an apparatus for consolidating concrete test samples include a tubular tamping rod with a reference disc slidably mounted thereon. When performing a quality control test, a worker pours a concrete specimen into a test container. The tamping rod is positioned adjacent to the container with its lower end at a maximum acceptable submersion depth relative to the specimen. The reference disc is then positioned to engage the upper edge of the container when the lower end of the rod is at the maximum acceptable submersion depth. When the worker reciprocates the tamping rod within the specimen, engagement of the reference disc with the upper edge of the container indicates that the lower end of the rod has reached the maximum acceptable submersion depth.

  • Patent number: 7387466
    Abstract: A tamper for imparting patterns through a die to a pliable surface, most commonly a newly poured concrete structure such as a walkway, is disclosed. In the tamper of this invention its base, including the integrated handle-receiving neck, is formed substantial entirely of an elastomeric material with a defined hardness, thus reducing or eliminating the severe physical shocks which are caused when a tamper strikes a die or a concrete surface at an off-line angle. The elastomer material must have a Durometer hardness in range of 50-95, preferably 70-95 and more preferably 85-95 as measured on the Shore A hardness scale. Numerous elastomers are suitable for use; polyurethane polymers are preferred. A single type of elastomer may be used for the entire base or two or more elastomers may be conjoined and assembled to form the base.
