An electronic, fully automatic overload indicating system was developed and successfully applied to mobile construction type cranes. A mini-computer monitors the signals from boom load and boom angle transducers. It computes the resultant percentage of rated lifting capacity based on the crane's rating chart. A plug-in program card furnishes the safe operating limits from the rating chart.
