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.
This calculates the metallic cross-sectional area in a rope and then uses this information to calculate elastic stretch in a rope that occurs under load. Click here to view our Metallic Area/Elastic Stretch Calculator.
This calculates how much rope of a given diameter can be spooled onto a reel of a given size. Click here to view our Drum Capacity Calculator.
This determines if the reeving system in a hoist block will be stable (no block twisting) or unstable (block twisting will occur). Click here to view our Block Stability Calculator.
This calculates the rated capacity for a sling used in a choker hitch. Click here to view our Choker Rated Capacity Calculator.
Enter any two known values:
This shows the metric size equivalent to imperial rope diameters. Click here to view our Metric Conversion for Standard Rope Diameters.
This calculates the capacity of a wire rope sling based on the type of rope used in the sling and the angles at which the sling is used. Click here to view our Sling Calculator.
