Abstract: In many types of construction machines, the frame assembly comprises a rear frame that supports the engine and drive train components and a front frame that supports the work implement. In this type of machine, the two frames are normally pinned together and the front frame is articulated with respect to the rear frame by a pair of steering cylinders to provide steering for the machine. In the area in which the two frames are pinned together it is necessary to provide structural support, especially in the hitch area of the front frame. The present invention provides a front frame assembly (12) that has an upper and lower hitch plate (118, 120) that are positioned between and secured to the rear portion of a pair of side plates (62, 64) defined by the front frame assembly (12).

Abstract: In many types of construction machines, the frame assembly comprises a rear frame that supports the engine and the majority of the drive train components and a front frame that supports the work implement and related structure. In this type of machine, the two frames are normally pinned together and the front frame is articulated with respect to the rear frame by a pair of steering cylinders to provide steering for the machine. In order to provide the required structural support for the components of the work implement and to accommodate the steering forces, the front frame is necessarily quite large. The present invention provides a front frame (12) structure that includes a pair of main side plates (62, 64) and a substantially planar support plate (74) that is mounted to a first end portion of the side plates (62, 64). The support plate (74) mounts an axle assembly directly thereto and defines a pair of mounting bores (84) that are positioned, on a rearmost portion of the support plate (74).

Abstract: There is disclosed a mounting bracket for securing tubular members and the like. The bracket comprises a pair of members shaped to define a substantially annular portion for encircling a tubular member, and is connected together by means of a dovetail joint at one side of the tubular portion. Tabs extending outward from the other side of the tubular portion provide means for securing the two members to supporting structures and to apply clamping pressure.
