Rope Drive
There are technical regulations for the rope drives of cranes, elevators, rope ways and mining installations not exceeding a given tensile force and not falling short of a given diameter ratio D/d of sheave and rope diameters. A general dimensioning method of rope drives (and used besides the technical regulations) calculate the five limits
- Working cycles up to rope discarding or breakage (mean or 10% limit)
- Donandt force (yielding tensile force for a given bending diameter ratio D/d)
- Rope safety factor, minimum breaking force (ability to resist extreme forces)
- Discarding number of wire breaks (detection to need rope replacement)
- Optimal rope diameter (economic reasons)

Famous quotes containing the words rope and/or drive:
“Rather would I have the love songs of romantic ages, rather Don Juan and Madame Venus, rather an elopement by ladder and rope on a moonlight night, followed by the father’s curse, mother’s moans, and the moral comments of neighbors, than correctness and propriety measured by yardsticks.”
—Emma Goldman (1869–1940)
“Certainly, words can be as abusive as any blow. . . . When a three-year-old yells, “You’re so stupid! What a dummy!” it doesn’t carry the same weight as when a mother yells those words to a child. . . . Even if you don’t physically abuse young children, you can still drive them nuts with your words.”
—Mary Kay Blakely (20th century)
