Lifting and rigging calculators
Calculate sling length, sling load, shackle size or center of gravity
In lifting and rigging work, precision matters. Small miscalculations in sling angles, tension loads, or connection hardware can lead to major risks on-site. That’s why we’ve developed a set of straightforward calculators to support day-to-day lift planning.
These tools are built for professionals — from rigging engineers to crane operators — who need clear numbers when planning complex or high-stakes lifts. Whether you're dealing with offset loads, low-angle rigging, or tight lifting points, the calculators here help you get quick answers based on real-world conditions and standard lifting formulas;
They’re meant to assist with decisions like:
- How much tension will be on each sling?
- What angle keeps the load balanced and within capacity?
- What size shackle is safe for this lift?
If you’re looking to reduce guesswork and improve how your lifts are prepared, these tools are here to help — fast, and free to use.
If you need help reviewing a lift plan or selecting the right gear, our team is available to assist with technical guidance, equipment recommendations, and compliance checks.
