History has shown that dependancy upon the crane operator to monitor loads and boom angle or load radius do not allow the margin necessary to perform the required crane functions with speed, accuracy and safety. Voluntarily and by legislation it has become necessary to develop automatic methods for monitoring, warning and limiting crane operation during critical lifts. A review was made of all regulatory requirements, desired operators aids, crane load ratings, crane operating configurations, load and boom angle sensing methods, display methods, memory methods and integration methods. From this review and subsequent design effort the Crane Load Moment system described in this paper was developed. (Se)
