How to Use This Calculator
- Enter the crane's Safe Working Load (SWL) in metric tons and the boom length in meters.
- Input the working radius and boom angle in degrees for the planned lift.
- Enter the load weight and rigging weight in metric tons.
- Review crane capacity at radius, total lifted weight, and utilization percentage.
- Keep crane utilization below 80% and ensure safety margin is positive before proceeding.
