Re: Elevators: Cascaded vs Continuous

We've used Spectra cable for several elevators and been very happy with it.

Our 2008 and 2011 elevators both used a thin variant of it with 800lb rated load, generally used as high-strength kite string. No issues with 2011 robot, ever. It's super lightweight, too.

Our 2012 stinger initially used the 800lb cable, but we eventually broke it by landing on the stinger. We replaced it with three 800lb cables braided at that tournament, then found some higher-force thicker Spectra harpoon fishing cable, which lasted the rest of the season.
