The frames of many construction machines comprise a complex compilation of fabricated sections or massive cast members that are not necessarily intended to handle a specific type of loading applied to the frame assembly. The present invention provides a frame construction that includes a pair of laterally spaced plate members. Each plate member has a first end portion constructed of a substantially solid plate. A second end portion of the plate members define at least one opening that provides an integral portion of a beam assembly. The first end portion is positioned in the frame construction to accommodate a first type of loading, while the second end portion is located in an area to accommodate a second type of loading.
