Sling loads
What it’s for — when you lift a load on slings, each leg carries more than a simple “weight ÷ legs” — the angle multiplies the tension. The Sling load calculator works out the real tension per leg and checks it against the sling’s rated capacity.
When you’d use it — rigging a multi-leg lift, to confirm your slings are strong enough at the angle you’ll actually use.
The Sling load calculator
Open Sling loads from the sidebar. You describe the load, the attachment geometry and the slings; Craneye returns the leg tensions and a pass/fail against the safe working load.
How to run a calculation
-
Enter the load build-up — net weight, a weight contingency, rigging weight and a dynamic factor.
-
Choose the attachment geometry (2-, 3- or 4-point) and the coordinates of each pick point plus the load’s centre of gravity.
-
Pick the sling type, hitch, and the rated capacity (WLL) per leg.
-
Read the result — the tension in each leg and whether it stays within the safe working load. It blocks a clearly over-loaded configuration.
