Lifting and Rigging Calculator 

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.
