Rigging Calculator: What to Verify Before the Lift

Published: September 2025 | By SlingCalc Engineering Team

A rigging calculator brings geometry, weights, and hardware limits into one model. Follow these checkpoints to confirm your lift plan is safe and documented.

Key Questions to Answer

Are load weights and centers accurate? Update them with the latest drawings.
Do sling sizes, shackles, and spreader bars meet the expected forces?
Will the hook travel keep leg angles within the safe window?

Using the Calculator Efficiently

Build the load outline and place pick points where slings connect.
Assign sling types and rated capacities from your inventory list.
Move the hook or lifting beam until angles and leg tensions stay in the green.
Check the validation panel for warnings about overload or low safety factor.

Team Communication

Export a PDF summary with the 3D view, forces, and any notes for the crew.
Pin the plan to your project board so the field team can review it before the lift.
Log any changes directly in SlingCalc so revisions are tracked.

Confidence with SlingCalc

SlingCalc highlights overload conditions instantly and documents the solve path. Use it to prove your rigging plan, answer auditor questions, and keep every stakeholder aligned on the lift sequence.

Reminder: Always perform a job walk and toolbox talk even when the calculator shows all-green results.
