NOTE: Enter values in shaded fields below in the indicated units of measure.

For 2-part reeving, the diagonal spacing values (Sp & Sb) entered below would simply be the spacing at each associated single sheave.

The results of this calculator are approximations only. The calculator is not intended for design.

Resulting plotted points landing within a wire rope class band indicate uncertain stability for that rope class. Points below the band will most likely be stable. Points above the band will most likely be unstable.
