From the perspective of the driver’s seat, TyrFil® polyurethane fill also provides better rough terrain traction and tire deflection (i.e. optimal tire contact area), which can reduce worker attrition and job absence due to a physiological effect called Whole Body Vibration or WBV. The impact of WBV may cause measurable muscular-skeletal and neurological injury to equipment operators. Aside from potential bodily harm to workers, WBV also costs companies utilizing heavy equipment thousands, if not millions of dollars, in lost work time due to driver absence during recovery, along with potential workers’ compensation and liability suits.
