Abstract
A crane safe load indicator combines signals representing the total loaded boom turning moment and the turning moment of the boom alone to derive a third signal representing the turning moment of the load alone. The third signal is compared with a signal representing the crane's maximum safe load moment to indicate available lifting capacity.
