![]() A reference is used to help clarify calculations. The calculation of the cci is as follows: radius * lifting height * capacity. The document explains how arane capacity index can be determined. ![]() Don’t forget to include adjustments for buckets, boom extensions, load blocks, hoisting rope and other attachments that will alter the lifting capacity of the crane or equipment used to lift the load. The load charts are specific to the make, model and configuration of a specific piece of equipment. What must you know when using a load chart? In addition to the above, there are a number of additional features that are designed to improve the overall performance of the system. The structural strength of the structure is what limits capacities above the bold line. The crane’s stability limits the capacities below the bold line. The bold line on the chart represents the separation of structural strength and stability. What is the bold line on a crane load chart? ![]() Load charts take into account the distance and angle at which the load is to be applied when calculating the lift capacity. This chart is used to make sure that the crane does not exceed its lifting capacity.
