<p>FRAME FOR SUPPORTING AN INDUSTRIAL LOADER BOOM ASSEMBLY A loader boom support frame includes opposite upright sides including double-walled portions that have their undersides interconnected by front and rear crossbars, the crossbars being adapted for connecting the loader frame to a pair of longitudinally extending track support frames. Secured to the rear of the boom support frame so as to form an integral part thereof is a transverse transmission housing, the connection of the housing with the boom support frame including a pair of premachined compression links welded in abutting relationship to both the transmission housing and the rear crossbar. The rear ends of a pair of loader boom lift actuators are adapted to be connected to the opposite sides of the frame at receptacles located just forwardly of the rear crossbar in general fore-and-aft alignment with the compression links. The receptacles are mounted by structural members so located that forces imposed on the receptacles by the loader boom lift actuators during operation will be transmitted directly to the rear crossbar and then to the transmission housing by way of the compression links.</p> |
