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.

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.
