When a crane is used to repeat the same load cycle a sufficient number of times, an analysis of the cycle times will produce a bell curve. On average most loads will be transferred in a certain time, with good and bad performances distributed equally on both sides of the curve (green).

Repeating the same test using an ICRAS system changes the distribution of load transfer times. The bell curve bulges towards better performance (i.e. faster transfer times) and the number of slow transfer times decreases. When performing the same task hundreds of times, computer-aided control performs better on average than a human operator (blue).

When the same task is automated, it is always repeated in exactly the same way. If the control method used is optimal – as the ICRAS system is – the result is a distribution in which all the load transfer motions are repeated practically identically and almost optimally. That produces a substantial difference compared to manual operation (red).
