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:
“Immortality without eternity is a rope with only one end.”
—Multatuli [Eduard Douwer Dekker] (1820–1887)
“Practically everyone now bemoans Western man’s sense of alienation, lack of community, and inability to find ways of organizing society for human ends. We have reached the end of the road that is built on the set of traits held out for male identity—advance at any cost, pay any price, drive out all competitors, and kill them if necessary.”
—Jean Baker Miller (20th century)
