             The Hansen UniMineR was designed with the ability to correctly lubricate either right side up or upside down, making it a flappable gearbox.  The author focuses on expressing the point to end users that they only have to stock one unit for multiple mounting configurations creating documented added value cost savings.  A +/- 3 degree tilt also makes the unit an alignment free design, allowing the installer more flexibility with no modification requirements to the split housing line.  The cast iron housing has reinforced ribbing for additional support and is also available in strong, ductile iron housing.  The units are assembled with grease purged seals, resulting in less maintenance up keep for the customer.  Output options include standard low speed output shaft, keyed hollow bore and finally shrink disc.  An inspection cover on both the top and bottom of the housing allows the end user to easily and conveniently inspect gearing, lubrication color and the input pinion quickly and efficiently. The inspection cover also allows one to view all the other internal workings of the gearbox without it having to be moved or disassembled.
