The bold line on the chart represents the separation of structural strength and stability. Any capacities below the bold line are limited by the crane’s stability. Any capacities above the bold line are limited by the structural strength of the crane.

What is crane capacity index?

In this document is explained how a “Crane Capacity Index” (CCI) can be determined. The CCI basically is calculated as follows: “Radius * Lifting Height * Capacity”. The result CCI is in Te ∙ m. To clarify calculations a Liebherr LTM 1100-5.2 is used as an example.

How do you calculate load lifting capacity?

Take the total weight of the load and divide this by the number of legs supporting the load. For example, assume a 2,000 pound load is to be supported by 2 legs of a sling. The above will give a total minimum weight on each leg of the sling of 2,000 pounds divided by 2 legs or 1,000 pounds.

How is SWL of Crane calculated?

To calculate the SWL in kilograms of FSWR square the rope diameter (D) in millimetres (mm) and multiply by 8.

  1. Formula: SWL (kg) = D2(mm) x 8.
  2. Formula: D(mm) = √L(kg)
