  • Gauge restraint load calibration system
    Patent number: 7451632
    Abstract: A direct measuring loaded gage axle assembly that measures track strength by directly measuring constant load on split axles as vertical loads are imposed by a hydraulic ram, and horizontal loads being supplied by horizontal rams through split axles and steel wheels to the railroad tracks enabling improved calibration to measure changes in track gauge indicating track strength condition and further including electronic data recording and comparison.

  • Track belt placer for placing construction materials and method for placing construction materials
    Patent number: 6422785
    Abstract: An infeed conveyor is provided with high pivot capability. High pivot capability is the capability to raise the elevation of at least one end of an infeed conveyor belt to an elevation higher than regular horizontal operation if the belt placer is operating lower than the surrounding grade. High pivot capability prevents the infeed conveyor from bottoming out on the grade of the haul road or adjacent pavement; and in some instances, high pivot capability allows use of the belt placer under conditions that belt placers without high pivot capability could not operate. Also disclosed is the ability for belt placers to be used to pave in both forward and reverse directions, whereas former belt placers could only pave in the forward direction. This is accomplished by the ability to rotate the discharge conveyor under one side of the belt placer, and changing the direction in which the belt placer travels.
