ALL calculation results and specification data on this site are provided for REFERENCE ONLY. Before any lift, you must verify capacities against the current manufacturer documentation for the exact equipment in use, and the lift must be planned and supervised by a qualified person as required by applicable regulations (e.g., OSHA 1926/1910, ASME B30 series, local equivalents).
This site is provided "as is" without warranty of any kind, express or implied, including accuracy, completeness, merchantability, or fitness for a particular purpose. Standards are revised periodically; data here may not reflect the latest edition.
The crane load calculator reports geometry (radius, angle, load moment) and compares your load against a rated capacity YOU enter from a manufacturer load chart. It does not and cannot estimate crane capacity. The shackle, sling, and wire rope calculators use published nominal data; actual hardware must be selected with appropriate derating for hitch type, angle, temperature, environment, and dynamic loading.
