Hello everybody,
I have a question...

Are there any studies concerning proper selection of the rope for gondola lift?

I need to carry out the theoretical considerations about choosing a proper rope for monocable gondola lift. and honestly i don't know how to bite it. i know there are different factors (http://www.safetysling.com/wr1.htm) but hm...If I'd like to make a gondola lift which moves on flat surface(street/transport) with good wheather conditions area - which rope would be good for way 2,5 km long(1,5 mile)? with...hmm..100 gondolas?
I know I made a specific question but It's quite important for me and I'd like to have some basis for my writing.
and I'm not lazy i made my google job, found a lot about ropes, but no specific samples, information about

I'll be grateful for any linking/theoreticall help

Martin

The most common ropes used in the ski industry are 6X25 filler wire up to 42 mm rope diameters, then 6X36 Warrington Seale for larger diameter ropes. The current cores used are a high density polyethylene inner core with a low density polyethylene outer sheathing that is heated and softened just before closing the strands onto it. This causes the outer strands to sink into to the plastic which allows the melted plastic to extrude out between the valley's. This creates a low stretch rope. I am partial to Fatzer AG mainly because they will back their product as well as backing their splicers. Many manufacturers sing a great tune, but when it comes time to back their product when there is a problem, it will be everyones fault but theirs.
Hope this helps.

6x25? is it this one as on the picture below?

if Yes, now I got the point.
Thank You Splicer.

hmm...and what about the distance between towers? how is it examined? I know it depends on many conditions. do You guys have any link with basics information about that?

Thank You
