Elevator Wire Rope
Steel wire ropes are one of the best choices for elevator
applications owing to its two main features: redundancy and detestability as
shown below:
Redundancy is very important for safety-relevant applications. If one of
individual elements is broken, other elements will take on its function and
remain in operation taking advantages of interaction between wires.
Detestability means the capacity to determine the end of
service life and the degree of bending fatigue of running wires. As fatigue
increase, more external wire breaks so that it is possible to estimate by
visible inspection before the condition becoming dangerous.
Normally, elevator wire ropes feature parallel strand construction for reducing
incidence of abrasion compared with ropes with cross laid construction.
Meanwhile, they have a high fatigue bending life and less wear to running
sheaves.
