  • Patent number: 4087101
    Abstract: A frame assembly for a tractor shovel or the like includes a front frame and a rear frame having generally U-shaped cross-sections. The frames are pivotally joined by a vertical shaft. A rectangular parallelopiped hydraulic fluid tank is internally mounted in the front frame, and its side and front edges are secured by welding or the like to the front frame plates. Similarly, a rectangular parallelopiped fuel tank is internally mounted in the rear frame, and its side and rear edges are welded or the like to the rear frame plates. The arrangement offers increased frame strength and rigidity with no increase in weight, and the tanks are better protected by reason of their internal mountings.
