Support frame structure for loader lift arms
A lift arm assembly has a pair of lift arms that are pivotally mounted onto the frame of a loader that has a forwardly pivoting cab. The forward ends of the lift arms each have a front frame assembly that is secured to the respective lift arm. The front frame assemblies includes separate box section frames with depending leg portions that have pivots at lower ends thereof for supporting attachments for the loader. The upper ends of the box section frames have sockets that receive the lift arms. The depending portions are offset inwardly from the lift arms, and tilt cylinders for controlling the pivoting of attachments are mounted on the depending portions to align with connections for loader attachments while providing clearance above the depending portions for forward pivoting of the cab. The depending portions are secured together with a torsion resisting cross member adjacent the lower ends to provide rigidity to the lift arm assembly.
