  • Patent number: 11821166
    Abstract: An internal support structure for fuel cells within a work machine having a rear end frame with an exterior frame wall in which the fuel cells are stored is disclosed. The internal support structure may include a radiator support housing, a first pedestal and a second pedestal mounted to and extending upward from the bottom wall. The radiator support housing may be disposed proximate a radiator opening of the exterior frame wall, and the pedestals may be disposed forward of the radiator support housing. A first rail may be mounted to the radiator support housing and the first pedestal, and a second rail may be mounted to the radiator support housing and the second pedestal. The internal support structure and the exterior frame wall may define fuel cell cavities for the fuel cell, and a component cavity from components of the electrical power system of the work machine.

  • Publication number: 20140306426
    Abstract: A front frame is disclosed for an articulated machine. The front frame may have a central tilt structure with parallel plates, a web member disposed between and connecting the parallel plates, and a hinge component connected to the web member. The front frame may also have mounting lugs connected to the web member opposite the base, the mounting lugs being configured to receive a pivot pin of a tilt cylinder. The front frame may further have two substantially identical lift structures located at sides of the central tilt structure, the lift structures being configured to receive spaced apart lift arms. The front frame may additionally have an axle mounting pad connected at a base of each of the lift structures and configured to engage a front axle of the articulated machine, and a bearing bore located adjacent the axle mounting pad and configured to receive a pivot pin of a steering cylinder.

  • Publication number: 20060254805
    Abstract: A low profile transmission cable for high frequency applications includes one or more inner conductors each having a substantially oblong curvilinear cross-section. A dielectric material generally surrounds the one or more inner conductors. A metallic outer shield generally surrounds the dielectric material. An outer jacket envelops the metallic outer shield.

  • Patent number: 5900588
    Abstract: A ribbon cable with improved skew control has a plurality of substantially parallel longitudinal conductors lying in a single plane, with insulation encasing the plurality of conductors. The insulation defines first and second outer surfaces which are substantially parallel to the plane of the plurality of conductors. A first sheet of extensible metallic foil is positioned adjacent the first outer surface of the insulation, and a second sheet of extensible metallic foil is positioned adjacent the second outer surface of the insulation. A third sheet of metallic foil is wrapped around substantially all cross-sectional sides of the plurality of conductors, insulation, and first and second sheets of metallic foil to provide a continuous electromagnetic shield around the conductors. A flexible jacket may be provided on the cable to protect the assembly.
