  • Patent number: 6971423
    Abstract: A log handling and cutting system which cuts logs into lengths, and allows for maximum use of fiber. The system includes equipment for singulating the logs, optimally removing the bark from the logs, scanning the true log image, cutting the logs to length, and sorting the cut logs arranged in a sequence of coupled operations. The logs are singulated using a dual quadrant singulation system to provide maximum singulation reliability, thereby allowing a single operator to attend to this process. Once singulated, the logs are fed automatically into a debarker where the diameter and volume are scanned and debarker-operating parameters are set for optimum bark removal. The log is then scanned, tree length, using a unique scanning system, which determines the true image of the log. This enables the determination by computer of the optimum bucking solution of the log as well as a proper sorting of the optimum random lengths.

  • Publication number: 20040195408
    Abstract: The present invention provides support frame for a tire assembly for irrigation systems that prevents the formation of ruts caused by repeated travel along a path by tires of a mobile vehicle or structure. The support frame includes a force transfer member connected between the support frame and the irrigation tower structure for transferring forces generated by the tire assembly to the tower structure. The support frame includes plural adjustable mounting features to accommodate a retro fit to a variety of existing units. The support frame further includes an adjustable compensation spring to adjust to forces applied to the support frame caused by uneven terrain. The support frame is adapted for use with corner sweeping units.
