This paper proposes the Rope Performance (total work done divided by the weight of wire rope) as present standard value to winding performance. It expresses the theoretical. formula and the simple formula to show the Rope Performance, and proves to be able to use the simple formula for calculation of the Rope Performance by the examples.
The values of the Rope Performance are as follows:
Rope Performance 240t·km/ kg for drum winding
550t·km/kg for koepe winding.
And the methods of determining and examining about the Rope Performance, and other values of winding performance are explained by the nomogram.
Besides. the author has obtained several results of examining about some actual vertical shafts.
