Winding/hoisting ropes extended life creep effect
Winding/hoisting ropes extended life creep effect
(OP)
Hi, can anyone point me in the direction of any information on the extended use of winding/hoisting ropes.
In particular the creep experienced as the rope gets older due to the load (permanent deformation)
Any books or standards or research articles where some information on this topic might be found.
I've done a bit on elongation under load but am yet to see something on creep due to extended use over time.
Regards

You would probably do well to talk with some of the engineering people at your wire rope suppliers, or people looking for your business. Don’t settle for the b.s. you get from the sales guys, get with their real engineering people. You can get elastic stretching from loading, wire by wire; and you will certainly get mechanical/relaxation stretching as the wires in the cable settle/adjust into a tighter bundle. Off hand, I’m not real sure about much creep if the wire rope is not stressed to a very high level continuously, or working at a very high temp. And, you probably shouldn’t be working the wire rope at those stress or temp. levels. Those wire rope engineers should have some info. or knowledge on this. You will extend the life and load cap’y. more effectively by running your wire rope over larger dia. sheaves, thus reducing bending stresses.
