Case New Holland (CNH, Amsterdam, the Netherlands) has lessened the level of steering noise in the cabs of its 821 Case brand and LW190 brand wheel loaders by utilizing Char-Lynn Series 20 steering control unit from Eaton Hydraulics (Eden Prairie, MN). The cab noise issue was great enough to hold the assembly line while the matter was investigated. Researchers at Eaton tested several units to isolate the problem and constructed working prototypes with a lower decibel output.
Finding a sound solution depended on measuring the level of noise and the feel of the existing steering unit, comparing those measurements to acceptable noise ratings, and incorporating results into a product redesign. Eaton was able to produce quieter steering units within nine working days, assuring the assembly line stoppage was minimal.View this technology here.
