Abstract:
An upper frame assembly for use in a skid steer loader machine having front and rear end portions, a pair of spaced lift arm assemblies connected at the rear end portion, and a centerline extending along a midsection thereof, comprising:a pair of spaced tower assemblies positioned on opposite sides of the machine centerline, each tower assembly defining a spatial region that is adapted for connection with a respective lift arm assembly therein;a pair of side members each having front and rear end portions corresponding respectively to the front and rear end portions of the skid steer loader machine, the rear end portion of the side members being respectively disposed within a portion of each of the spatial regions and connected to the tower assemblies, the front end portion of the side members extending longitudinally therefrom; anda crossmember assembly extending between the pair of tower assemblies for connection therewith, the crossmember assembly being positioned to define with the front end portions of the side members an open access area at the front end portion of the upper frame assembly unobstructed by structural elements of the upper frame assembly so that an open pathway is established from an area outside the upper frame assembly to the crossmember assembly between the side members and to define with the rear end portions of the side members and the pair of tower assemblies an open service area at the rear end portion of the upper frame assembly which is separated from the open access area by the crossmember assembly therebetween.
