  • Publication number: 20100189501
    Abstract: A soil compactor/driver that includes a housing and a substantially sealed chamber defined within the housing. A weight assembly that is carried by the housing and includes an eccentrically mounted weight. The weight is supported for rotation within the chamber by a pair of sealed, spherical bearings that do not require maintenance. First and second end plates are adapted to receive at least a portion of an associated sealed bearing and the housing defines first and second openings associated with the first and second end plates. The end plates, bearings and weight are arranged to be preassembled outside of the housing to form the weight assembly which is then installable as a unit into the housing which substantially reduces manufacturing and maintenance costs.

  • Patent number: 5927665
    Abstract: The mounting system for mounting the implement to a boom assembly forming part of a construction vehicle, such as an excavator, pedestal boom, and backhoe. A pair of spaced apart side plates include aligned apertures for receiving adapter plugs sized to be received within the apertures and for resisting relative rotation therebetween. Each adapter includes a transverse bore which is sized to receive a first pin member, such that each transverse bore is of an associated pair of adapter plugs defines the pin diameter that will be accepted, as well as partially defining the distance between a first pin member and a second pin member. Each adapter plug defines a flange portion having a surface abuttably engages a side surface of its associated side plate. The flange portions of an associated pair of adapter plugs define thrust surfaces for a boom member coupled to a pin carried by the adapter plugs. The thrust surface may be machinable to adjust the lateral spacing between an associated pair of adapter plugs.
